Will Global Warming Push Trees to Extinction?

intro


ASL

Plants and animals are adapted to live in a certain climate. For example, polar bears live on and around the Arctic Ocean, squirrels live in temperate forests, banana trees grow in the tropics and cactus grow in deserts.



ASL

A desert cactus would die in a tropical rain forest. The cactus roots would rot. Cactus plants grow slowly and would be shaded by the fast growing tall jungle plants.



ASL

A banana tree would die in the desert. The banana tree would freeze in the cold nights. The long dry months would wilt the banana tree's large leaves.



ASL

The temperatures on the Earth are rising. If the temperature continues to rise some of the plants and trees in your community may become extinct. The model in this lesson helps you determine which trees and plants will be threatened with extinction by global warming.
