Example text

Some plants and animals have not been able to adapt to their rapidly changing or disappearing environments. Some have become endangered, and others have become extinct. And while extinction is part of Darwin’s natural selection process, the recent increase in the extinction of species is believed to be due to human behavior, not nature. It is important that humans understand the effect they have on the survival of other species. Guaranteeing a wonderfully diverse world for the future begins with choices made today.

Antarctica’s chilly waters support a surprising amount of plant and animal life. Phytoplankton support a dense population of tiny shrimplike krill, which in turn feed many larger animals like penguins, whales, and seals. A hundred feet down in the water, food is scarce and temperatures are frigid. Animals have adapted by slowing their bodies down so they don’t require as much food and heat energy.
