It is really simple:
Planet Earth does not grow.
But humans keep multiplying.
Less of everything for everybody.
Less room for plants and animals.
No matter how much we struggle to protect air, water, forests and wildlife,
the rapidly growing number of humans eats up all our efforts in no time at all.
The battle for resources has already begun,
and yet the problem's main cause is still neglected by most and even denied by some.
Is Homo sapiens sapient enough to set his own limits ??
Or is his intelligence just barely sufficient to fill his stomach and pockets,
and to displace all other forms of life ??
Will we end up in a dark grey world of poverty, poison, hunger and death ??
There is only one way out: stop overpopulation!
