Sigh...do get a grip and stop scaring yourself and others, will
ya?
Rainforest will only disappear by 40 years time, NOT the human
race! We aint gonna disappear just because the
rainforest had been cut down, and the land cleared for more
efficient uses
In any case, the 40 year figure are only stats. You and I should
by know the value of stats by now and how much of a value it
stands. However rest assured, mankind must always ensure
sustainable developement and such stats ONLY serves as a warning to
be more ecologically minded.
What can be destroyed, can be rebuild and replace, but once you
and I are gone, it is forever. Human lives MUST always come first.
So quit your worry and make sure you don't spend all your money now
and become a pauper in 40 yrs time, cos humanity will still
continue to live and prosper then.
PS: Is there any scientific basis to your claim that rainforests
produces oxygen, let alone produces oxygen for the world? Or would
you prefer to change 'rainforest' to marine algae
instead responsible for Earth's oxygen?
