You have the right to question the law of gravity as well. However, there
are more useful things to do with your time than complaining about facts.

as we should question everything which is pushed at
us as these are.

You have problems with reality, do you? Reality pushes at you only because
you reject it. Relax and enjoy.

It's a perfectly good theory, but not really proven.

Ignorance of the term 'theory' shows that you do not have a background to
critise science. Theory is factual ( proven ). Hypothesis is speculative.

Widespread acceptance is not proof.

When the widespread acceptance includes the professional scientists who are
directly studying the problem, yes it does. No other criteria for proof
other than widespread acceptance by those with the background and education
to understand the data has ever been proposed as 'proof' in science.

Furthermore there are other more
likely causes for damage or change in the environment, such as
contamination of the air and water.

Irrelevant to the issue. One truth does not drive out another. Please get a
clue. The fact that you are trying 'diversion' speaks to your lack of facts
or serious logic.
