I think that we would all agree that it would be wonderful to have a pollution free planet, but with many other things, there is differences upon how to do it, getting enough international cooperation, then the one thing that so eloquently screws everything else up, and that is politics.

As with many other matters, I think that the government should give incentives for thinking and going green, but not try to ram policies down the throat of companies in an attempt to force them to do it.

There is no doubt that we have come a long way in the area of pollution; and public awareness has increased exponentially over the years… recycling etc.

As to what you were saying about Global Warming, I agree with you fully; again, this is an area that politicians would better serve if they allow scientists to do their jobs instead of pushing their ideologies down people’s throats.

In fact, for anyone that can recall the paintings of George Washington and his men crossing The Delaware River, over to Trenton, they will notice that there are major ice sheaves in the water.
That is no coincidence…science has shown, during that era, The Earth was going through a mini ice age, and they believe that it was caused by several volcanoes, erupting in Iceland; then the sulfur dioxide spewed into the air, caused a thick haze to spread throughout the world, causing climate chaos across the entire Earth. Please see: Laki Eruption

I have no doubt that man contributes to the problem, however, I tend to believe that most of this is a phenomenon of nature, and we will likely see more mini ice ages, and warming periods in the future.
