There's something about volcanoes.
They also produce gas, 10 billion tons a
year.
One gas volcanoes emit in huge
quantities is carbon dioxide,
a gas that causes the greenhouse effect
and global warming.
250 million years ago for hundreds of
millions of years,
life on the surface of the earth had
faced numerous
challenges to its survival, but nothing
on the scale of what was up about to
happen.
Water vapor is by far the most important
greenhouse gas
helping to make our planet habitable. To
understand our climate and to understand
life on Earth,
we need to understand how the water
systems work.
Wetlands and a river's ecosystem
are known as reparian corridors and
are nature's
built in flood control. As water levels
rise
wetlands accommodate the rising water,
spread and store the influx and
reduce the velocity of downstream flow.
