Strange Days on Planet Earth
Part 4
Over 70% of the earth's atmosphere is covered by water. The animal in the ocean are migrating at the same rate as the animals on the land. The ocean scientists are trying to capture a type of plankton so they use a black net so they will not see it coming after them.. Some of the oceans may die out because of the heat on the earth. Scientists discovered that the crabs heart beat stops when there is 2 degrees in the water change. In Trinidad, the lady explains that while growing up not many kids had asthma ,but now they all do and she does not understand why, also there were two other disease. Lake Chad in Nigeria had great waters but it is now all dried. Lake Chad once produced many fish, Nigeria has built a lab to examine them. The people believe that the dust on the Sahara desert at been causing children to have asthma. As earths climate change occurs dust from the Sahara is blowing to the Caribbean and the Americas. If enough people began to conserve their energy, it will make a big impact on the earth.


Part 5
In Caroni Valley, Venezuela there has been numerous amounts of floods. Some people are going around the world, trying to capture animals and rescue them. In lake Guri many of it is man made.Before the flood in lake Guri, it was made of plants, and it was a home to animals,today it is strangely quiet. On the Iquana Island the scientist are trying to find any destruction that may have been caused to the animals and the land or what may have caused a flood. Herbivores and other animal predators are spreading diseases and are spreading lime disease and rabies. The fore they have to execute many species. The Yellowstone National Park is the worlds first national park and it is still around today. The vegetation there has been decreasing there so the animals are not going to be able to survive living there anymore:(. While the scientist were looking through the park the realized that it is not Global warming who is killing Aspen so they look to wild fire. The Aspen has stopped regenerating since the 1920's. They found out that the wolfs are going instinct and that is why the forest is dieing out because they mean a lot.
Today the coal reefs are dieing out. Only the top of the reef is alive, people are looking at the coral reef trying to find clues.In a near by fish market, a man is trying to find clues of why the Coral reef has collapsed. The disappearance of the large fish is unusual to them but not to the others in Jamaica. 90% of the large fish, over the years have gone missing. We have been over fishing the sea, taking away the large fish and also their prey. If we have no fish then we have no ecosystem. They have had to work harder to capture large fish. The people are wondering if their plan will work and if the larger fish will return. The team has been trying to find signs of recovery but they are hare to find. Smaller prey are returning and fishermen are starting to catch the larger fish again. The return of the fish are welcomed by the scientists and fishermen.



Part 6
The scientists are researching water animals. They have been looking around and it appears that water is cleaner than it has been in many generations. 20 different types of frog species has vanished. Some male leopard frogs has eggs growing inside their intentions. They believe that the water is causing the deformation of the frogs. The deformed frogs they find are coming from water with atrazine, but the frogs that are healthy come from clean water. Being in water with atrazine may cause the male frog to grow ovaries, grow eggs and become a female organism ,it is a threat to this species. These water problems may cause trouble with this species. There are many reasons the water is not clean, two of them are pollution and contamination. Some scientists have been taking tissue samples out of dead beluga whales and found out that they are non-useful and are very contaminated. When you mix chemicals together, they may become toxic so in a whales body it may be a risk of cancer.
