"STRANGE DAYS ON EARTH

PART 4
Plankton is a very high number animal.But now the plankton are going down.But they have seen that the thing that makes them go down is that the hotter the water is the less plankton there is.Animal in tide pool are moving because of warmer weather but many cannot move.For animals that live in water and the water go as one degree up they are hugely hurt and then this hurts the food web.The whole earth is interconnected with the weather.In islands in the Caribbean there is a huge problem that was not there a long time ago the problem is asthma.The problem for all this is dust and lots of it.These dust comes from Nigeria and it is all sent to the Americas.In Trinidad they have found that the day after the Sahara dust the emergency of asthma attacks increased.The problem on see fans disappearing is that the dust that comes that it Carry's a pathogen that kills dust fans.
PART 5
In Venezuela there was a huge flood and now they are raising to save the animals that lived there.But the benefit is millions of energy for them because of hydro energy.In another lake in Venezuela there is something just like that but it is way further in death.This lake was something different it had many plants and animals they all had a roll in the community.All over Venezuela they are finding the same pattern.Animals are getting more crowded and crowded.Scientist are thinking that the problem for this is because the predators have left and the prey have gone high up.People say it is our fault of the number of prey going up because we take the predators from the environment.At yellow stone park the river has widen and the answer for this is plants stopped growing on the banks.There are more changes that start from less beavers,birds,and trees.The trees are the most important and that is bad for the park.The trees have steeped growing because of the 1930 when they stopped regenerating.One scientist thinks that the problem for the disappearing trees and widing banks are the loss of wolfs.Scientist believe this because as soon that the wolf killed other animals come and eat.Another thing that they thing this is because when the wolf where taken the elk could eat anything and with the new wolf there they kill and they cant eat as easy.When they put the wolfs back in the envierment all the other animals starting coming back.Ranchers are worried about wolfs comming back in the envierment because they aet all the lifestook.A coral reef in Jamaica there is a problem the problem is that there is alge on the coral.The scientist that live there record the coral reef.They hace a tube that they can see what it ooked like along time ago.And something they discovered was that they collopsed when the alge started growing.At amarked they anly seel small fish and that means something big has happen.In the ocean over the past 40 to 50 years there has been a los of 90 percent of big fishes.The alge that comes to the reef is the hervevors taken from the ocean.In the same place there are trying to put reserves to try to save the big fish.And it looks like it is working.The survival of big predators is on us and back then the survival was on the predetors.

In many places there are missing frogs .When you see one you think it is completely normal.But when you see something inside of it it has a enomely.One of the scientist thinks that the problem to this is a chemical called atrizine.To test this he goes to his college and has the same frog but in one frog the water has atrizine and when they diggestid it the frog with atrizine it has the enimaly.He also discovered that the more dose the frogs arent hurt the less they are hurt.Many farmers are helping and tryng to stop the atrizine.At st lorence river in Canada other scientist are looking for beluga wales.These wales have the highest cancer rate of all the wales.Doesn't od chemicals are found in the wales.Somw ways that they get chemicals are it going threw the skin ao eating fishes that have chemicals.In a lake of Georgia there is a chemical that is called mercury in the water it turns even stronger.Over the food chain it grows and gets stronger.Some one that lives there is using a technique that uses plants to take mercury out of the water.Many plants have the power to take chemicals.Not many people believed in plants doing this.But he got it and now plants can observe the mercury.In a farm where they grow sugar cane they have to use many chemicals to take of the bad stuff.Much of this stuff gets to the ocean and in this case the farmer lives really close to the great barrier reef.In the great barrier reef there is this animals that eats the reef the name is Crown Of Thorn.The main corlprite is farms that release nitrogen witch come from farmers.The scientist that whant to prove this they are gong on the reef and seeing that where more nitrogen the more Cronwed Thorne there is.Back in time farming was different they had ponds and trees to stop runoff.One farmer has desided to put more trees instead of more cane.If more farmers did this there would not be alot of pollution.All over the world sharks,wales and tuna are geing contaminated by chemicals.Some scientist are trying to see what makes them get contaminated.The animals that they are focused right now is called the MolaMola.The scientist are putting tags to see where they go and how they get chemicals.On this information they have seen that animals spent alot of time near the shore and getting contaminated.So the animals are forerunners to what comes in the future.
