"Strange Days on Planet Earth"



(part 4:)


Over 70 percent of the world is cover by water. Scientist think that the temperature its going to increase about 3 to 10 times over the next century. Because of the increasing temperatures the food, fishes and species are dieing. The plankton are dieing even thought here are millions of them they are increasing a lot in the population. Krill are plankton too. Scientist are studying the plankton to be able to know what is causing them to die. The plankton level is 20 percent less than how it was back on the 1950's. Scientist think that the plankton is dieing because of the different types of climate change because sometimes the water gets too cold or too hot for them to be able to survive. A lot of the different species are moving north but not all of them survive because they can not re-locate. The crabs heart can only race 2 Fahrenheit for it to stop beating.


The crabs are already living at the edge because of the temperatures are racing too much for them to be able to be alive. They are a lot of things that have been dieing and because of that they are creating a lot of deceases to the people to who live close by the oceans like for example asma. Many people are getting asma and the own people are not doing anything about it and by that i mean that they are not even using inhalers or nothing like that to help their selves. IN Nigeria there it use to be this beautiful part of ocean but now it dried up and its like it has been a desert for years but it hasn't. They have been trying to figure out what was the exact thing that was giving the people asma in that are and that did found it out and it was this fungi in the dust. they where thinking about it and they tough that why is the dust having fungi now and not earlier. Its up to us eather we want to make a change on the earths climate change or not to make a change and we might now be able to change every ones mind but we can change our way of thinking.

The predators in our natural world are disappearing. In Caromi Valle, Venezuela they have been looking for over 1000 animals one by one and they have not find all of them and the only ones that they reach are the lucky ones because they are taking them to a good place. Lake Gury which is close by Venezuela have been totally hand man made and in here almost all of the plants have been dieing and only the plants that are in the top are the ones that usually survive, the predators who are the strongest are the ones that are able to survive the most because of their speed and potential. leaf cutter ants have been increasing for more than 5 times the number that they use to be so they have been taking the food that supposed to be for other animals. In here they are very extrange battles of foods because of the increasing or decreasing of certain species of animals that live in this habitat. There have been a lot of questions asking if the number of predators are going to be increasing because if they do, we are not going to feel save in our houses or neighborhoods. There is a picture of a forest that was so big and green and now that have took a picture of it and it looks like if the forest have just disappear but it dint disappear it was actually burned and cut down but they are still wondering what did exactly made that forest disappear so they counted the trees rings to determinate how old the trees are and they where all like about seven years old. In this forest there it use to be full of wolfs but between 1970's and 1980's about 100,000 wolfs got killed and they where called an endangered specie in the U.S.A. Beavers are one of the preys are are being really damaged because there number of population is decreasing. Ranchers are complaining of the wolfs because they are killing their sheep's and their other animals.


The predators from the ocean are very different from the ones that are in land because of the way that they kill their prey. When a predator kills their prey, the prey leaves behind algae and that is causing the coral reefs to die. Scientist love coral reefs and they are trying to find out what can they do to make the coral reef to stop dieing. Scientist got dirt but when they where looking in the dirt they fond coral on it and they where investigation what was happening to the coral and how the dust and the animal killing was affecting them and they did found out and it was all because of the changing temperatures and because of the algae. In Jamaica there is not big fish because they have been overfishing because fish is the only thing that they have. In the last 40 years we have lost about 90 percent of the big predatory fish. Smaller predators are coming back to the resorts and they are keeping up with their ecosystems and the fishers are finding big fish again.

Researchers are finding different creatures that they have never seen before like for example they have found fishes mixed with starfish and things like that. Investigators all around the world are trying to find out whats going on this creatures and why is the water getting so polluted well they have found out that some of the water is getting cleaner but they are just fulling their selves because nothing good is really happening to the water, the only thing that is really happening is getting it more polluted. there is only 20 species world wide of Leprafrogs and this frogs are so special because they have female and male parts so its hard for them to reproduce, that's why the species are decreasing. Frogs from clean water pretend to be healthy. The Beluga whale is becoming extinct because they live on rivers so that means that they are a lot of toxics going into their mouth and bodies so now scientist took an d.n.a. example so that they could know all of the things that they are eating and they found out that they are over a million bacterias inside their bodies so it was like if the are becoming a Bactria too. Scientists are saying that if there is something that is affecting the animals that means that is affecting us too. Mercury is found on the top predactors and is very concentrated. There are people trying to find a way so that the mercury doesnt go into our water. A lot of plants already ave mercury into their nutrients. There are farmers that are starting to worrie a about the things that they are goign to have to do to be able to keep te plants giving fruts and to keep them alive. Great berrier reef is one of the places that they are scared about because they know that if the mercury level increases the reef is going to die. Nitrogen, airosol and Mercury are going inot the ocean and we do not want the plants to die because if they die and people do not do anythind ot try to help them people are just goign to keep on doingthe same thing and by saying the same thing i mean that people are going to keep on using this chemicals and they are going tokeep on trashing the chemicals into the ocean. Sharks killer wales and shrimps have been found dead because of the too many chemcals that they have gooten inside thier body.
