I think there is no doubt about this statement. Because of our pollution the greenhouse effect is increasing the climate changes and especially the global warming. This causes the glaciers to melt and so the sea-level is rising. We pollute our soil, our groundwater and we deforest an incredible amount.
Although the situation is so alarming, globally we are not changing our habits. The Kyoto protocol was a nice piece of paper but not much more. The three biggest pollutors which are China, USA and India do not want to become greener due their thought it would be detrimental to their economies.
Since the great polluters do not want to change and discourage the smaller countries to, these problems will increase in the future. There will be less arable land because of desertification as can be seen in China for example and therefore less food while the number of people around the world is increasing. Owing to the rise in sea levels there will be less arable land on which to live.
All these issues will surely cause violent wars in addition to natural disasters. It is late but we could try to reduce our ecological impact to salvage what we can.
