Global warming endangers tropical plants and animals

University of Connecticut scientists conducting research in Costa Rica have come to the conclusion that global warming endangers many lowland plant and animal species in the tropics.

While many people are concerned about the effect of global warming on the polar regions, even more harm may be done to the environment around the tropical regions of the planet, the researchers said.

The researchers said that because the tropics are already so hot, many of the species there are living at the maximum temperature at which it is possible for them to survive.
