While in once sense your answer is obviously correct, it is a finite planet, there are few indicators that we are anywhere near the tipping point. The biggest problem is probably the upsurge in simple minded fundamentalist religious belief, which tends to denigrate science and promote breeding like rabbits, but the evidence from data like the national census shows that once people become educated and for want of a better term 'Westernised' their breeding rate generally drops. The UK for example is currently not replacing it's population by breeding.
My bold Got to disagree with that, many parts of Africa & the M. East are already suffering from severe water shortages leading to deforestation & desertification. A lot of Asia & S. America is similarly seeing huge deforestation which is leading to problems. The population of much of those areas are growing unsustainably due to the moronic anti birth control of the 2 leading religions, Islam & Roman Catholicism.
Unless this changes and rapidly we will see yet ever increasing problems which due to ever increasing population mobility, the developed world be overwhelmed by tsunamis of incomers fleeing from those areas. We have seen the beginnings of this in the last decade or so but it will worsen!
