What are the indications for the future of humankind?

Human civilisations have been around for a paltry 12,000 years. People have dominated over nature and thereby villages, towns, cities and mega-cities have cropped up. The resources are limited but our human population has increased rapidly. So we are battling with other species for the limited resources. Hence a great depletion of resources is underway. Further the burning of fossil fuels and pollution have created a blanket of carbon-dioxide around the world. Thus, our tenacy on this earth is shortening day by day.

There is a long controversy over the environmental changes. The global temperature is increasing. The ice-caps and the glaciers are melting. There is every likelihood of overflooding in the ocean. On the earth and in between the nature, we are bent upon decaying the ecological balance through deforestation. Many species of forest have become extinct. Thus there is a great danger of human survival. Our future is quite bleak and the scientists are warning us about all these dangers and changes in the environment. If this goes on at a rapid speed, the day is not far when the nature will swallow the human beings.
