Could the growth in the human population (and the resultant increased pollution?) have something to do with the Ecology, Environment and Global Warming?

Overpopulation occurs when the population of a living species exceeds the carrying capacity of its ecological niche. In common parlance, the term usually refers to the relationship between the human population and its environment: Earth. http://en.wikipedia.org/wiki/Overpopulation

The Population Reference Bureau predicts continuing population growth. Their charts indicate that the rate of growth will be less in about 50 years. In reality, other than statistics for the last 25 years only, there are no facts to support the assumption that trends in population growth will remain low for the next 50 years in the future. The rate of growth in the previous (26 years) was much higher.

Of course there are food and other natural capacity and resource limits. They may eliminate or reverse growth trends, as might a global pandemic. Even though the annual rate of population growth has decreased in the past 25 years, the population continues to grow. If none of that happens there is no reason to assume the rate of growth will actually continue to decrease. http://en.wikipedia.org/wiki/World_population

Although there is still much discussion and controversy within religious organizations some still maintain that birth control should not be used. They maintain that it is in the “natural”, or in “God’s Order”, not to use artificial means to minimize the number of births:

“The Church, nevertheless, in urging men to the observance of the precepts of the natural law, which it interprets by its constant doctrine, teaches that each and every marital act must of necessity retain its intrinsic relationship to the procreation of human life. (12) “ The Vatican; The Holy See

And, that dogma continues to be challenged within, and outside the Catholic Church http://en.wikipedia.org/wiki/Criticism_of_the_Catholic_Church .

The number of human beings living on this Earth always will affect the world’s Ecology, Environment and Global Warming.
