With a phenomenal rise in human population, natural resources are being heavily taxed all over the world. No doubt at present, total global production is nearly enough to match the human demand for energy and materials if we judiciously distribute the resources available to us.
However, looking forward to future scenario, the situation appears pretty grim. Nearly all agricultural production, produce of animal husbandry, the world fisheries etc. have to be diverted to support the human society. While the number of mouths to be fed is regularly rising, degradation of natural ecosystems, deterioration of fertile soils and pollution of environment threatens world’s food production. In near future, it will be difficult for the world’s food production to keep pace with the growing demands.
