Who says it's not?
John... energy to produced ethanol comes from growing
yeast if that is the method of production. The energy
that the yeast consume is free. Could it be used for
other useful purposes in the environment? You need to
explain your concern.
Well, let me put in my two cents worth. The growing of anything needs
water. What water is used to grow something, is water than is not
going to
be available for the people to use. It is always a tradeoff between the
needs of the people and the needs of the agricultural industry. If
there is
not enough water to do both, then we need to find another source for the
water that is needed, or one or the other will have to pay the price.
Second, agriculture uses pesticides, fertilizers, which I do not think
anyone is going to argue is good for the environmnt. And the more we
grow,
the more pesticides and fertilizers we will use. As for yeast, how much
yeast do we really need?
