Strange Days on Planet Earth

Part 4: over 70% of earths surface is coverd by water. 3% of earths water is fresh water/ drinking water. little crabs in the coast can die when the water get only 2 degrees warmer. if they die it can efect the ecosystem. as earth gets warmer some animals will die and some will not. kids that have azma are noticing that its increasing. biggest lake in africa dryed out and now there is nothing left of the lake. what wa scausing the sea fans to die out was the same desiese they found in the dust. dust has been blowing over the atlantic for a millenium, and we are noticing problems now.

Part 5: Predetors some animals can die because of floods because the can get stuck on the tops of the trees that are out of water with no food. wolves may be a large inpact in the ecosisytem. by killing ilk the wolves may be changing the land scape. because the wolves were killed and there worent any left, most species of animals were gone. but noe that there are some wolves back, the species are back also.

Part 6: follow the water. at least 20 frog species have vanished all throughout the world. rain and wind can spread chemicals to frog habitats and damage them. frogs from clean water are healthy and frogs that are from water with atrecine are not very healthy. arecine can harm animals. beluga whales can be in danger. dozens of chemicals have been found in the body of the beluga whales. water is become toxic because of the fertilizer thats in the water called atrizine. if the toxic affects any animal it will affect US. some plants have natural abilities to prevent toxins. many of the chemicals that farmers use can get eroded to the rivers. farmers are starting to plant more trees to prevent the chemicals from getting to the reefs.
