Is nature a boon or a curse to man?
Answer It isn't nature that is the curse to man. Man is his own worst enemy. I don't know how old you are but I am in my late 50's and the air that I used to breath when I was ten years old was a lot cleaner than it is today, thanks to man's inovations and greed for money we have no one to thank for the way the earth is screwed up, but ourselves. Look at all the polution in the air today. How many people die of Cancer each year is staggering and it's not only cigarette smoke that causes Cancer. Many people die from Cancer each day and they never smoked a cigarette in their lives. If anything we have to be grateful that we have mother nature and green forests to soften the blow of acid rain and chemicals that flow through the air from one Country to the other.
Is the air cleaner today or was it 20 years ago?
In the USA, the air is much cleaner now - as anyone who was alive 40-50 years ago will tell you, especially around some of the bigger cities. This is due to several major environmental laws passed in the 1970's. Elsewhere in the world, particularly in the developing world and especially China and India, the air is much dirtier than it was 20 and 30 years ago. Some of the cheapest energy and manufacturing techniques are also the dirtiest. These countries are just now beginning to deal with their air pollution simply out of necessity. Poor air quality takes a tremendous toll on human health when it is so severe, and you can attach a monetary value to these damages.
