It does not solve the problems it addresses.
Problem, the scientists do not know how to
solve the root problems without losing their
tempers because the root problem is that
the mass of humanity are behaving irresponsibly
in having population booms and having theologies
that ignore the importance of excellence in ecological policies.
So, scientists follow the dictates of that
back-slapping bunch, the corporate executives,
and concentrate, as they're paid to do, to find new ways to feed us more food for less
money.
The food crops we have already, with moderate GE advances, would be adequate for our food
market if the other matters were addressed.
Since the other matters are not being addressed,
no amount of GE will save the world.
