"Strange Days on Planet Earth"
Part 4: In the video it was talking about how the temperature is raising fast and how they think it is going to increase 3 to 5 more degrees in the next century. Most of the earths area is water. 70% of the earth is water,most of it covers the pacific. It was also talking about how scientist are studying krill ( larger plantain). All of the animals that live in the oceans are driven North because of global warming. There are these little crabs that live in the ocean and if the water changes 2 degrees, the little crabs will die. The water climate is changing because the sun is hitting the water, so the water is heated up. Part 5: In the video it was talking about how dramatic changes are happening in the world. In Lake Guri it was once lushes and green, but now all of the plants are dead and only the strong plants have survived. It is like this because of a big flood that hit there, it destroyed everything there. Animals on iguana island are so crowded because all of the trees are left, so they fight for food, shelter, and they become antisocial to others. Since the predators are disappearing the preys are growing like crazy. People are thinking about instead of killing the predators we should bring them back, but if we do that we are risking our lives doing that. In Yellow Stone National Park a lot of aspen trees are disappearing. People are thinking climate change is doing this, but no it is because of the wolfs that are killed that are effecting the aspen trees. With the wolfs back in Yellow Stone Park it has brought back green grass, trees , and now beavers are starting to build homes in the water. Scientist were looking at the coral reefs to see the changes in them. They saw that in the coral reef, plants like coral have not been growing for months. In St Lucia the coral reef is way better than the one in Jamaica.
Part 6: In this part of the video people were looking for the leopard frog. They were saying how the might look strong and healthy, but in the inside they have things going wrong. The number of the frogs are declining. They think that atrizine (pest decide) is what is killing the frogs. Frogs that come from atrizine water are deformed and the frogs that come from clean water are healthy. The atrizine mostly effects the male Leopard frogs than the females. The Beluga whales are in trouble because the are contaminated with chemical mixers. With this the wales can get cancer. Scientist have been trying to come up with a way to prevent their cancer. In the water poeple fish in are contaminated with bacteria, so the fish that people fish have bacteria too. So every fish they take they can't take it home, they have to throw it back. Divers are really interested in a fish called the Molamola because of the chemicals that are inside of it and what they do. If we pay close attention to the animals in the world, they are telling us how the enviorment is.
