There are many forms of life on earth, including human beings.
Life exists in a variety of
conditions.Some forms of life live ~ in a
watery environment, like the oceans.
Other forms of life can be found ~
in very dry areas like 『deserts.However, for any form of life to exist, conditions must be right.
When conditions are not right, that form of life will become extinct.
To become extinct means to die out
completely.With global warming, global temperatures are rising.
As temperatures rise, the polar icecaps will melt.
As the polar icecaps melt, ocean levels will rise.
Areas of some countries will soon be under water.
Conditions must be right for life
to exist.Millions of years ago there were forms of life that no longer exist.
When conditions changed, these forms of life died out.
One extinction event happened about
250 million years ago.This was the largest extinction
event of all time.Many forms of life became extinct.
96% of all life in the oceans died
out.Most insects also became extinct.
This event happened over a period

are still unknown.Possible causes include large volcanic
eruptions and global warming.Some scientists believe that there
were several causes.

foods are safe to eat.Human beings can not live in a poisoned environment.
Therefore pollution is a major threat to our existence.
Humans need temperatures to be in a
comfortable 『range.To be in ~ a comfortable range
means to be neither 『too hot nor too cold.1) With global warming, global temperatures are rising.
2) As temperatures rise, the polar icecaps

ocean levels will rise.4) Areas of some countries will
soon be under water.People will be forced ~ to relocate
from 』flooded areas.In nature, even small changes can sometimes have large effects.
It』s difficult to predict what』s
going to happen.The entire ecosystem that we
depend on is changing.Some of these changes are irreversible.
Irreversible changes can not be
undone. (because they cannot be reversed)Let』s hope that humans are smart
enough to understand how the world is changing.With 『more understanding we can
make better choices about what to do.
We can face the challenges of pollution and global warming.
