Another global issue that has attracted much popular and scientific interest in
recent years is tropical earth, and few processes are likely to have more
dramatic evidence of our ability to transform the face of the earth, and few
processes are likely to have more profound biological consequences. Humans have
been altering and removing the earth’s forest cover for millennia, but nothing
in that long history matches the current pace of forest destruction in the humid
The great blocks of forest that straddle the equator in the Americas, Africa,
and the Asiatic tropics are the most complex and exuberant expression of the
earth’s green mantle. Although they include many different forest formations, it
is possible to divide them into two broad categories; tropical rain forest of
the ever wet tropics and tropical seasonal forest of the seasonally dry tropics.
The sum of the two categories is now generally called tropical moist forest.
Although they clothe only some five per sent of the land surface tropical most
forest are believed species of organisms. That we posses only a very incomplete
inventory of life on the earth reflects in large part how little we know about
tropical forests. Much will remain for eve unknown, because each year a vast
area of forest is converted to other uses. As the forest vanish as, quite
literally, they go up in smoke so too do countless spices of organisms. Current
trends threaten to expunge much of the remarkable cornucopia of tropical life.
The process is irreversible extinction is for ever.
