scarcity and limited resources

. 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..

? 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 ..

Resources which are in limited amounts and cannot be renewed are called non-renewable energy resources. Fossil fuels like coal and petroleum are some examples. Petroleum products are energy-rich components of carbon which have undergone anaerobic degradation with the ..

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 reserv..

Conservation and Protection of the Environment - 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 conserve..

Non-renewable or conventional energy resources. Most of the energy, which people are using, is derived directly or indirectly from the sun. Non-renewable energy resources are those, which have been in use since a long time. Availability of petroleum is limited. Petro..

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..

Environment refers to the natural elements that make up the earth and surround living organisms The abiotic or physical aspects of the environment refer to elements like air, soil, water etc. The biological or biotic components of environment are the plants and animals Natural resource..

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 scientists ..

Therefore 300x + 150 y 15,000 dollars The mathematical model for this problem is Maximize Z = 50x + 18y (objective function) Subject to the condition with non-negativity conditions Note that in both the examples the conditions are linear inequations; these mathematical models which tell..
