Electricity is obtained from flowing water. Water from the dam is allowed to flow through the tunnels at a high pressure. Turbines convert the potential energy of the water into electrical energy. About 23,800 MW of energy is generated by hydel power in India. Hydel power requires constru..

Waste Management - We are an integral part of the environment. Our activities change the environment around us. Changes in the environment affect us. Environmental problems like depletion of the ozone layer and waste disposal are issues that have to be dealt with serious concern. In our d..

. Speciation does not intend to convey the dieing out of one inferior species giving way to superior ones. Species adapt to the conditions available in their environment. Some older and simple species live on quite effectively. The scorpion, is one of the more primitive invertebrate which has lived..

>Fossils also show evidences of evolutionary relationships. Their study provide knowledge about the extinct forms, and also provide links between two groups of species Organisms have emerged due to evolution by stages and adaptations for new functions. Intermediate stages can be traced by studing t..

Environmental Consequences - The energy source that we actually choose depends on various factors like the cost, the ease with which it is available, the efficiency of the technology available and the environmental damage that will be caused by using that source. It is thus deba..

Dams contribute enormously to deforestation and the loss of biological diversity. They can also result in potentially huge accidents during disasters like earthquakes. The embracing of centralized mega water management and regulation has also led to two more criticisms. The politicization and mi..

Exploiting any energy source disturbs the environmental balance and must be harnessed judiciall..

Health is considered to be the state of perfect functioning of body and mind, unhindered by diseases. Disease is the malfunctioning of the organism or a part of it due to infection, inherent weakness or environmental stress that upsets the normal physiological functioning of the organi..

Question: Name any four environmental problems faced by today's world. Answer: Four environmental problems being faced by today's world are: 1) Population explosion 2) Pollution 3) Global warming 4) Soil erosi..

Population Control - Increasing population is a serious issue, particularly in developing countries. It is necessary for every generation to produce more off springs because many individuals do not survive to reach the reproductive age due to natural causes. However, man has upset this equation as ..
