ReplyDelete1. Disasters and impacts such as these can last anywhere from hours to years. There were oil spills that went as long as 4 and 5 years.
ReplyDelete2. As the video mentioned, people living near the coast can create habitats for birds flying over to support them.
3. Chemical dispersants are drills that break up particles in the spill.
These types of incidents can go on impacting the environment for decades. Keep the birds away from the oil or oiled areas. Chemical Dispersants are are chemicals that are dispersed and eat away things like oil spills. They make cleanup time much easier and more efficient.
ReplyDelete1. The impacts of events such as the BP oil spill can last up to decades.
ReplyDelete2. Solutions towards helping migratory birds include local residents setting up artificial habitats for the birds to nest in for a short time.
3. Chemical Dispersants are drills that break-up oil, removing it from the water.

ReplyDeleteDisasters like this can last for months up to years. Once it stops its not gonna go away right then and there. It takes a long time depending on how severe it is. In the oil spill case I think it can last for up to a year to a year and a half.
ReplyDeleteWe should try and make small habitats for the birds to migrate to so they won't have to go looking for food in the gulf where all the oil is. If we can do that i think that we will be able to decrease the number of birds getting hurt by the spill.
This video really showed how our choices impact everything we do
ReplyDeleteThese types of incidents affect the environment for Long periods of time and sometimes forever. It really depends on how bad the incident is. An oil spill that has as much oil as this one did, will do a lot more damage than an oil spill with less.
Truthfully I don't believe we should mess with the bird population. Nature works itself out and doesn't need our interference. I know that sounds cold, but we need to let nature deal with that.
When an oil spill of this magnitude happens it's very hard to get It all cleaned. Many animals, bird and marine life, live in the gulf and all of them were harmed and even us humans are harmed because fisherman can't fish so their jobs are in danger and the fish and food from the ocean that we eat are covered in chemicals. A big oil spill like this can last very long like even 3-5 years and will have an effect on us, the animals, and the earth for a long while until it has all been cleaned or distributed to other places. Chemical dispersants are chemicals that kind of eat up the oil in a way. A solution to help the migrating birds is to try to keep the birds away from the oil and have more places where people can volunteer to clean birds, and other animals effected by this horrible disaster.
ReplyDelete1. Every oil spill isn't the same length. They can last for a few days or a few years.
ReplyDelete2. We could make little habitats for the flying birds.
3. Chemical dispersants are things that remove the oil from the surface of the water.
That's extremely sad what's happening to those birds and there isn't much we can do about it exept just try to clean up the gulf as fast as they can and try to keep the birds away until it's cleaned up.
ReplyDelete3. (Edit) Chemical Dispersants are *surface-active agents called surfactants that aid in breaking oil into smaller droplets.
ReplyDeleteThese types of incidents can impact the environment for a very long period of time. These types of problems can cause aftereffects that can negatively impact the environment. One solution can be to provide additional habitats for the birds, but as the video says, it would not be able to completely solve the problem. Maybe we could put something at the bottom so that birds would not try to find food at thebotton of the gulf. This video talks about how birds are the most visibly harmed by the oil spill and how there are many problems happening or soon to happen that most people would not think about.
ReplyDeleteThe impacts that the oil spill creates effects the environment for six months, at a minimum. The gulf spill began in July and is expected to carry on in December. Along with the loss of life, companies and citizens of those states are losing both money and food.
ReplyDeleteAs for migratory birds, there are several solutions to provide solutions. These include tracking the migrating birds and cleaning the ones that have already passed on due to the spill. This effects the people's view on the spill because many of the dead migrators go unseen and taken into labs.
Chemical dispersants remove oil from The water by bringing out the more natural chemicals and reducing the harmful chemicals.
For about twenty years the oil spills will impact the gulf for possibly 4 decades. But since there is open water and other pros it may take less time.
ReplyDeleteTo insure the safety of the migratory birds they are building habitats and cleaning up most of the exposed.
Disperants are chemicals that are sprayed onto oil slicks to speed up the process of natural disposition.

ReplyDeleteThis site has info about the dispersants being used down at the oil spill. If the site doesn't work, then google: what are chemical dispersants and click on the second article.
These incidents impact the environment for a very long time. Usually forever because it is never the same again.
ReplyDeleteWe can provide bird sanctuaries to guide the birds away from the impacted area. Most, but not all, birds will go but it will lower the death toll of the birds. Especially the endangered ones.
Chemical Dispersants: A liquid or gas combined with a mixture to enhance dispersion or to maintain dispersed particles in suspension.
Chemical Dispersants are chemicals sprayed into the oil to speed up the cleaning process.
ReplyDeleteThe incident will have a long term affect. The biologist in the video said that it could take 20 years to clean up the different ecosystems. They have to remove all of the oil, replant habitats, and fix the marshes that are popular bird attractions. There also could be some short term affects. We have to wait for the oil has to stop leaking and, with the help of volunteers, the animals need to be cleaned off.
ReplyDeleteAn solution that we can use would have to be cleaning certain habitats that birds will need in order to survive. Like marshes, mud, and clean man made lakes. I remember this video that was teaching certain types of birds to follow an airplane for a safe migration because they were threatened. If this is possible, than we can lead the birds to a safer location.
These types of impacts can have long term impact on the environment, or can go away quickly. Oil could remain in the gulf of Mexicobfor a long time, and may affect the animals even after it's gone.
ReplyDeleteWe could help the birds migration patterns by keep trying to clean the beaches, because it would be hard to alter the actual migration patterns.
Chemical dispersants remove oil from water by breaking it into smaller droplets.
Oil spills can impact the environment anywhere from decades to a couple months. Ways to improve migratory bird populations is by keeping the birds away from the oil, providing additional habitat for them, and cleaning off the birds that are found with oil on them. Chemical Dispersants break up the oil into smaller droplets and remove the oil from the surface of the water and into the water column. Dispersants are also toxic and cannot be used in shallow or near shore waters which is where most of the birds are found. They may be useful, but I don't believe they are safe for the animals that live near the shore.
ReplyDeleteIt differs from the different types of incident this one however was a very major problem and it lasted about 3 months but even though the oil spill stopped leaking the oil in the ocean, the animals, and the vegetation can stay around for many months to come.
ReplyDeleteSome things that people can do to help the migratory birds population is by making small habitats for them to live in so they won't depend on the ocean as much as they would for food. The more habitats there are the more birds people are saving.
Chemical dispersants are Chemicals that help remove and break down oil.
These incidents such as an oil spill definitely impact the location of
ReplyDeletethe spill in great ways. People surely don't want it to impact the
environment for a long time, at the minimum 3 years at the most 7
years is the number I would say because people help clean their area
and help study about the environment and they are being affected. We
could tag some of the bird and once the population has been wiped out
so severely than they could boom the populations' numbers. I think
that chemical dispersants are really bad even though they work, but
basically they re making the water even more toxic of chemicals and
even oil. A chemical dispersant is obviously a chemical, but what that
chemical does is to keep the spill from clumping together and
spreading out even further than before. I know that it works but it is
just endangering the lives of the species that just happen to be
there.
These types of incidents can last from a few months to multiple decades. It depends on where is it, what is effected by it, and who's doing what to help fix it.
ReplyDeleteWe can get more people to help clean the animals and eliminate oil, we can reroute the birds migratory path, we can designate "bird areas" that are the first places clean while we clean the other areas, etc.
The length of time this type of incident would take differs depending on the severity of the issue. The oil spill will take a very long time since it is a very large and severe problem. Although it has been stopped, the damage has been done. The water has been contaminated, the plants and wildlife have been hurt and there is danger near them.
ReplyDeleteWe can build reserves for them and habitats within those. We can recreate swamps by creating conditions close to what they are. We would need to keep them from gong to the contaminated areas, so we can use nature. We can get photos of the birds predators and place them throughout to scare them away, or we can almost cover up the areas that are contaminated. We could also use dispersants.
Chemical dispersants are chemical agents that cause the natural and physical breakdown of oil. Eventually, when the oil is broken up into much smaller droplets, bacteria can feed off the dispersant and oil to completely remove the hazard. However, sometimes they are poisonous.
Chemical dispersants are chemicals that have components that help it break up the oil into smaller drops. They also help to remove oil that is on the surface. Unfortunately the dispersants are slightly toxic which could be bad for the water.
ReplyDeleteChemical dispersants are chemicals that are supposed to remove the oil from the surface of the water. They are supposed to enhance the natural chemical and the physical breakdown of the oil. Eventually the dispersants and oil droplets will make food for the bacteria in the ocean.
ReplyDeleteThe oil from the oil spill could remain in the area for well over 20
ReplyDeleteyears but with chemical dispersants the oil will remain for a
significantly shorter amount of time.
Although solving the migratory bird problems won't be easy, there are
some things the government is doing to help. They are replacing
habitats and barrier islands to create a safe area for birds and
mammals. They are also cleaning up oil and using dispersant to break
down the oil before it reaches the shore line.
Chemical dispersants are used to break down oil. Dispersants are
chemicals that have surface-active agents which break up oil into
smaller droplets. Once dispersant is placed on the oil the oil becomes
"crunchy" so it is easier to clean up.
The chemical dispersants used in the Gulf of Mexico are two forms of Corexit, but a political debate has spouted due to the amount of the dispersants sprayed. Non-BP employees are concerned that the dispersants used may be harmful to other animals, resulting in a failure to reign in the spill.
ReplyDeleteChemicals dispersants are chemicals that are put in the water and they break down the oil and clean up the ocean.
ReplyDeleteThese oil spills are so severe that it will be a long time before we will be able to clean it up. Incidents like these are a big problem. They are not just something we can ignore we have try and fix this problem now. It does not just effect the fish, it also effects the humans and the birds. If there are no fish for the birds to eat, then the birds have no food and they could starve to death.
ReplyDeleteWe can help the birds by helping clean off the oil on the feathers. We can also provide the birds safer, cleaner places for the birds to migrate to.
Chemical dispersants breaks up the oil so that we can help the fish become free from oil spills.
Oil spills can majorly effect the environment. Depending on how severe and how large the oil spill is, the oil can pollute the waters for a very long period of time. Years, or even decades. Oil spills effect not only the fish and underwater animals but they effect other land animals who depend on the oceans for water, food, r even living close to the spill can be threatening. Many migratory birds coming from a different location are also effected. Many people are trying to help the many birds by cleaning the ones that are in life threatening conditions. I believe this is very helpful but we can't clean every bird that is effected! We need to come up with a way to keep the birds away from the oil spill entirely. A way to do this is blocking off the infected areas, or leading the birds away from the whole spill. Chemical dispersants help break down the oil into tiny minute pieces. But scientists are concerned that these chemicals will harm the animals.
ReplyDeleteProblems like this can last for months, even years. If we don't do something now it'll only get worse. Billions of migratory birds will die if we don't rebuild habitats. A chemical dispersant is a chemical that breaks down the oil in the gulf. This chemical may get rid of the oil, but the animals are suffering more from the dispersant than the oil itself. This dispersant is a HIGHLY toxic substance and is killing lots of migratory birds. Millions of migratory birds.
ReplyDeleteSome oil spills can last years, but it depends. This ones gone on for a couple months now, but it could go on much longer, you never know.
ReplyDeleteWe can build separate habitats were the water is clean, but we can't make the birds go there. We just have to hope that they will go there instead of going to some of the more oil filled waters where they are likely to die or suffering from being injured or oiled.
Chemical dispersants are chemicals that are put into the water to help clear out some of the oil and make it clearer water for the birds to be safe in.
1. Oil spills can last from months to years. The time can also be longer or shorter depending on how much oil was spilled.
ReplyDelete2. We can provide solutions by setting up habitats fornthe birds for a resting spot for the birds.
3. Chemical dispersants are chemicals that break up oil and can decrease the time it takes to clean up an oil spill.
1. Disasters like these can last for decades. In the video, they referred to a disaster that occurred 20years previously and they mention that it was still impacting the environment.
ReplyDelete2. We need to create new habitats for birds migrating south. Otherwise, they're water isn't drinkable and the food not edible. They need safe places to stay to continue on with they're travels.
3. Chemical dispersants are objects that help breaking down oil naturally so that it sinks to the bottom of the ocean. The bacteria in the ocean eat it up and water becomes cleaner.
I now have a whole different perspective on the oil spill and how it affects migratory birds. I hate to see animals in such condition. What if you were one of those birds? How would you feel?
ReplyDeleteThese incidents can stay in the ecosystems for decades, as with the Exxon-Valdez spill. Hopefully this leak can be contained, but water and any other liquids in the water have ways of getting around, ie; evaporation and acid rain. One solution to the bird problem is to put a lot o f food right out on the beaches so that the birds have more energy and can keep going and completely avoid the oil spill. Chemical dispersants are solutions that make the oil start to break down, making it buoyant. After it has broken down sufficiently, natural processes take over and bacteria eat the oil. The problem with dispersants is that they can be toxic and cannot be deployed in marshes or shorelines.
ReplyDeleteWhat is happening to the birds in the gulf is a mass species disease in a way. The oil spill is poisoning them in a way that is fatal. This oil can hang around for an extremely long time. Decades maybe.
ReplyDeleteWhat chemical dispersants are is a chemical that should remove the oil from the gulf, letting the ecosystem recover (although being a slow recovery). However, these chemicals have ingredients in them that may harm the animal, more so than the oil. A risky move by scientists may have a worse effect on the environment. It is even thicker, by theory, than the oil itself. This is a gamble, but I'm not sure people should be dumping chemicals if it has a chance to be even more negative.
The effects a disaster of the magnitude of the BP oil spill can last for years. The Exxon Valdez spill happened 20 years ago, and you can still see the damage. We can help the bird migration by creating new and restoring old habitats and by cleaning the water to the best we can. Chemical dispersants are chemicals used to disperse particles. (in this case, the oil in the water) Unfortunately the dispersents that are being used now are possibly toxic.
ReplyDeleteThese spills usually last a long time, and at such a big mass, this can possibly go on for a decade. Haven't we learned our lesson before with the Exxon Oil Spill? The solution for these birds who are migrating into the gulf, is to build a new habitat for the birds, Thats not going to work on it's own, we are going to have to put food in their habitat for them. That won't pull all of them in though. Chemical dispersants help remove oil from the water. It isn't that easy though. The substance in chemical dispersant is toxic to fish and other sea creatures. It's one problem after another. The only solution is to clean it up and make sure it never happens again.
ReplyDeleteThese types of incidents can impact the environment for a long time or a short time. It depends on what we, the people, do about it. Huge disasters such as this oil spill or even global warming will impact the environment forever, and cannot ever be fully taken care of.
ReplyDeleteAs for solutions to the migratory bird problem, there are few. We could find a marsh for them to stay elsewhere, or instead do what should have already been done and clean up the oil spill.
Chemical dispersants are chemicals used for breaking down oil when it's spilled in water. However, it won't help the birds much, since it's toxic...
These incidents completely disrupt the ecosystem affected because they first affected the animals on the surface, then the oil sinks and hurts the bottomfeeders, which than causes a chain reaction that will eventually hurt everyone the chain. As in the valdez spill, the effects lasted for 20 years. In the ixtoc spill, oil could still be found thirty years lateer in the gulf of Campeche.
ReplyDeleteTo save the endangered species, we can trap them and take care of them to make sure that the population levels can remain high.
Chemical dispersants break up clumps of oil and spread them out so they don't fall to the sea floor. In the deepwater horizon spill, corexit 9500 is being used so it does not fall to the sea floor.
Effects of events like this can last for years. The oil can eventually break down and "disappear", but it could still be there, causing damage to the wildlife. It could still be decreasing the population of the endangered species making their home in the Gulf. To improve their population, we could breed them in captivity and release them while still young so they don't learn to depend on humans.
ReplyDeleteTo help clean up the spill, the idea of chemical dispersants has been tossed out. Chemical dispersants are chemicals that change the surface tension and such things so that the oil disperses easier. It sends oil into something known as the water column, which has to do with the shifting of water and it's currents. Staying in the water column helps the oil to break down.
oil spills are very hard to get rid of, and can last anywhere from a few days, to a few decades. If we can isolate the migrating birds in an area away from the spill, by moving them and herding them to an area fit for a variety of habitats along the non-oiled coast areas, then we may be able to save hundreds of thousands of the birds. A chemical dispersant is a certain mixture of different chemicals used to clean up and eat away at various spills and chemicals. the dispersant being used at the gulf of mexico is Corexit, it is a very highly toxic dispersant made with almost all deadly and dangerous ingredients.
ReplyDeleteSituations like these can impact the environment for a long time. To help the population of migratory birds people can help clean the oil off of them. The chemical dispersants are used to enhance a natural chemical in the water and physical break down of oil on the water's surface and below the water's surface. The chemical dispersants being used in the gulf have some toxicity to young fish, crustaceans, and mollusks.
ReplyDeleteOil spills are amongst the deadliest man made disasters, they can kill thousands of birds and fish and destroying habitats. We need to ever thing in our power to clean this mess. But in the mean time we have to make sure that we save what we can by giving the birds an alternate habit to live in while we clean up the oil. Also another way we can help is by developing new more environmentally friendly dispersant to get rid of even more of the oil.
ReplyDeleteEvents like this can take years, even decades to stop impacting the environment. The exxon valdez oil spill's impact can be still be seen today, from twenty years ago.
ReplyDeleteWe should rebuild habitats of the birds and continue to wash off the birds found covered with oil
A chemical dispersant is a toxic chemical that is used to break up the oil from the spill. BP has dumped an estimated hundred thousand gallons into the gulf.
How long do these types on incident last?
ReplyDeleteIn my oonion, I think indefinatly because even if the get all the oil out of the water, there is still destroyed land, hundreds of dead animals, and sly this oil could possibly mutate some of the creatures infected. If a fish has been swimming in oil polluted waters (agd lived) it's chemical make-up xould b e distorted snf if s bird were then to eat that fish, then that mutated fish sir now in it's system. The effects of this could be like that of DDT.
In what ways cano we provide solutions to improve migratory birds?
We could, for one, get the stupid oil out of the water, restore the nearby shores and islands, and check to make sure that none of the animals in the affected area were mutated and could cause harm to feature generations. In the meantime, if we can train the birds to fly a different path (like Fly Away Home) aery from the affected area, we can avoid more harmed birds that nerd to be cleaned. Also, if wr can get international help on this, that would help to raiser money to save this ecosysytem.
What are chemical dispersants?
Chemical dispersants break the oil into smaller droplets and into water columns and then it is dispersed which reduces the toxicity level. These droplets become food for for marine bacteria. This way, supposedly, it's no longer on the surface and animals and coasts are no longer affected. But does it really work? A big problem is that the dispersants are toxic. They cause the oil to remain suspended in the eater, rather than sink or float. Medical hazards are ado present with the dispersants (such ad pregnancy problem to the mother and fetus). And can it be these dispersants that can mutate the animals? And not just in the open water (it's not put in shallow waters), but it can be carried to the shallow waters by currents, fish swimming into shallow waters, and by US eating food caught from animals there or around that swam through it.
The oil spill itself can be cleansed in a few months to a few years, but the after effects can last possibly decades. This can possible kill many species that eat poisoned fish.
ReplyDeleteWe 'could' build a closed reservation or something of the sort, but that would just interrupt the natural cycle of things.
Chemical dispersants help break down the oil so the . But scientists are concerned that these chemicals will harm the animals to the point where we are killing more birds, fishes and other species than the oil spill itself.
Incidents such as these can affect the environment for months, years, and even decades. It all depends on what we do to fix what wee have broken, or quite possibly destroyed.
ReplyDeleteOne way that we can help migratory bird populations is through breeding programs. Another is to take measures to ensure that their habitats remain protected and free of an type of contaminant.
Chemical dispersants are currently being used in the Gulf to help eat away the oil. But, really, we're getting rid of one terrible substance by replacing it with another, which makes very little sense. Official statements have now been made by the company that produces these chemicals saying that they are...
To be continued.
*How long do these types of incidents impact the environment?
ReplyDeleteThey can impact the environment for years, even decades because even if a majority of the oil is removed it still has after affects. For example, the oil gets into fish's systems and kill them, but what about what was effected by that fish's death. Whether it was a larger fish, shark, bird, or other predator, they have less to eat, then they die away. So whats affected after them? Once an oil spill has happened it will affect animals and plants, and even abiotic factors, for a long time, usually until those affected adapt to it, if they survive.
*In what ways can we provide solutions to improve migratory bird populations?
We can create sanctuaries to help rebuild the different species populations with as minimum human contact as possible so they can hopefully go back into their habitat, and breed in nature as well when they are mature. We can also try to teach young birds to follow a small plane that shows a different route during migration. If they learn to follow this path then they can steer clear of oil infected areas. The new path would also need to
* What are chemical dispersants?
They lower the toxic level of the oil and help breakdown the oil so other bacteria can finish removing it. But, Corexit is toxic as well, which is being used by BP. So, does it really help at all to break down one chemical with another chemical, and introduce something else toxic into the environment in the process?
