The current hype over the environmental issue is unnecessary. DYA?

In the article “The Truth about the Environment”, several environmental issues were debunked and after reading this article, I feel that the current hype over environmental issues is slightly exaggerated but not totally unnecessary.
Firstly, it was widely thought that our natural resources are running low. However, the scarcity of natural resources is due to the rising costs of locating and extracting them. However, i feel that by realising this, it only tell us that the time to derive alternative sources is extended because it is a fact that our natural resources will one day be depleted.
Secondly, the Malthus claim got us worrying for the future. His claim was sound, human population growing geometrically whereas food production can only increase arithmetically, this will result in severe food shortages in the long run. However, this will only come true if the human population is indeed increasing geometrically. But the fact is, we are facing a declining birth rate where our population will one day reach a maximun of around 11 billion people.
Lastly, pollution is not as bad as once thought. It is stated that the air today is much cleaner than that of 1585.
Thus, all these show that the hype over environmental issues are a little exaggerated but because of this false alarm, the world is more concern about the well -being of Mother Earth, which is a good thing! =)
