The concept of sustainable development is being threatened. The principal biological systems of the earth are under pressure. Fisheries, forests, grasslands and croplands are being destroyed. In a protein conscious and protein hungry world, over-fishing is common everyday. Forests are disappearing fast. The tropical forests, ‘the powerhouse of evolution’ face extinction. The world is losing about an acre and a half every second. Grasslands are being converted into wastelands and deserts. Croplands deteriorate. The most dangerous animal of the world that has caused this destruction is the man himself. His greed and claims have made this earth a scorched planet of advancing deserts and ailing environment.

Man’s villainy continues unabated. Over-population is making a mockery of all human progress. More mouths need more grains. More men mean more fuelwood. It means deforestation at a large scale. The choice is quite clear. Either we control population or face perpetual poverty. Man’s plundering of natural wealth and resources must bo stopped.
