scarcity and limited resources

Natural resources that are limited in nature and are liable to be degraded in quantity and quality by human activities are exhaustible natural resources. Examples are forests, soil, wild animals, minerals, fossil fuels etc. The understanding of the environment and its..

? One has not anticipated some of the impacts of industrial and technological advancement. When the industrial revolution started some 250 years ago, the world population was at 600 million - that seems like a lot of people but now the world population is now almost ten times at 6 billion and will ..

Question: How do you classify our natural resources? Answer: We can classify our natural resources into two categories: (a) Inexhaustible resources: Renewable resources such as solar radiation, air and water. (b) Exhaustible resources: N..

Conservation is defined as judicious use to avoid wastage of materials and degradation of environment. Conservation of environment involves the conservation of the natural resources. The non-renewable resources have to be conserved as they cannot be replenished. The reserves of ..

. Such misuse may create natural imbalance. Many of resources are limited and can last only for few years. Misuse of some resources has gone to such an extent that resources have already become rare and near extinction / damage. It is very important that ever..

Population grows in geometrical proportions but food grows in only arithmetical proportion. With the ever increasing demand on food grains, fodder, fibre, vegetables, fruit, sugar and oil, there is an urgent need to increase crop production, as our land resources are limited. O..

Water is essential for life. The types of plants and animals distributed in water bodies greatly depends upon the nature of water, fresh water or sea water. The organisms have to face different problems of water scarcity or abundance, so osmoregulation is required for their proper functi..

Humans depend on the forests largely to meet rapidly growing demands for timber, fibre, fuel, fresh water and food. All use forest produce in one form or other, e.g., when used as timber, paper, herbs and spices. Modern approaches in forest conservation have found that enforcement of forest laws ..

Introduction - The mathematical models which tells to optimise (minimize or maximise) the objective function Z subject to certain condition on the variables is called a Linear programming problem (LPP). During World War II, the military managements in the U.K and the USA engaged a team of scientist..

A sigmoid curve is characterised by a lag phase (wherever the growth rate is negligible), positive acceleration phase (wherever the growth rate is moderate), logarithmic phase (where in the growth rate is high) and negative acceleration phase (where in the growth rate is 0)...
