Global warming is having a significant impact on hundreds of plant and animal species around the world -- although the most dramatic effects may not be felt for decades.The globe has warmed by an estimated average of only 1 degree F over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F. Global warming could lead to a mass species extinction. Some scientists predict as many as a third of all species will become extinct by 2050.Ecological collapse is major bad news for all living things. Global warming has forced U.S. plants and animals to change their behavior in recent decades in ways that can be harmful. some plants are flowering earlier in the spring than ever before and some birds breeding earlier. In addition, species from Edith's checkerspot butterflies to the red fox have been gradually moving northward or to higher elevations, where more tolerable climate conditions now exist. Some of these species are also disappearing from southern, or lower elevation, portions of their ranges.

It's sad that we may soon experience a mass extinction. People need to stop and realize that we need to take care of the world that we live in.
