In the last 500 million years，there have been five times
when life on Earth has almost ended.
There have been five mass extinctions in the history.

die out 1，000 times faster than normal.
It is human activity that is causing species to die
out much faster.
Of course，as we humans depend on so many species
for our survival，we would also be at risk of dying out.
Man is also at risk of dying out.
Can a sixth extinction be avoided？Experts say that it
is not yet too late，if we take action now.
The sixth extinction can be avoided if we take
