Cuts would constitute the nation's first restrictions on carbon dioxide, a gas that has no direct effect on human health — in fact, it is the bubbles in beer — but that many scientists have concluded is already altering ecosystems and weather patterns as it accumulates in the atmosphere.

As behaviorally modern Homo sapiens spread out of Africa more than 50 000 years ago, their advanced hunter - gatherer societies helped to cause the extinction of more than half of Earth's mammalian megafauna, yielding trophic cascading effects on ecosystems coupled with the direct effects of landscape burning to enhance hunting and foraging success.
