"Strange Day on Planet Earth"


Part 4

Earth's Temperature will rise 3- 4 times in the next century
Over 70 percent of Earths surface is covered in water.
Plankton wait to eat until night.
Tide pools contain many different water organisms
Crabs heart stop beating if its a 2 degree difference and kills it.
if they die then the predator that eats it will be effected too.


Trinidad:
Kids have more asthma now then back then. Sahara Dust
Lake Chad in Nigeria has dried up over the past 50 years.
Dust from Africa is effecting children in Trinidad.

Predators:part 5

Is the disappearance of trees and coral due to the lack of less predators.
Animals and insects are becoming less active and more destructive. More animals are giving people rabies and lime disease. Aspen trees are disappearing. 1930 Yellowstone's last wolf died. Animals depend on the kill of the wolf because they also feed off of the prey. Brought back wolves to keep the cycle going in Yellowstone. More plants are growing meaning there is less elk eating it meaning that the wolves are getting their feedings. Having the wolves are good and bad because they are keeping the cycle going and then there are wolves eating live stock. Under water Predators and coral. Coral reefs are dying because they are being suffocated by algae. Jamaica has lost almost 90% of their large fish. The good things are that some fish species are returning. Also Fisherman are starting to catch bigger fish again. "Can we live with them or Can we Live Without Them?"

Part 6: Troubled Waters: Health of water signs in animals. Leopard frog is showing signs about the water. Atrizine is harming the leopard frogs because they are being blown to the waters and making them sick. Waters that are contaminated by atrizine are deforming the male frogs and waters that don't have atrizine in them they are more healthy. Waters are collecting synthetic chemicals that are harming us and the environment. Hidden in the black waters are beluga whales. Canaries of the sea because of the songs. These animals are the animals that have the highest rate of cancer. Dozens of chemicals are in these beluga whales and when belugas die because they have so much chemicals that they are sometimes known as toxic waste. Some chemicals by themselves might not be deadly but if they are mixed with other chemicals they can become dangerous. If we affect the animals it affects us. Fish are contaminated with a type of mercury and only 90% of the fish you get are safe to eat. Some people are trying to stop the contamination . Plants provide most of the remedy to kill the mercury in the water. Crown of Thorns have taken over the bottom of the sea and are killing coral reefs and has been spreading nitrogen and it has been unresolved for 40 years. All they heave to do in order to keep all the farming chemicals out of the water is to plant more trees to absorb the chemicals. Tuna. Sharks, and Whales all have chemicals in their tissue.
