slower than their rate of consumption. It might be understood via taking the example of manufacturing procedure of various fossil fuels. How Fossil fuels are produced: The three most frequent fossil fuels represent the three states of matter as; Coal is solid‚ Crude oil is liquid and Natural gas is gas. These might be refined further for the production of their byproducts for instance; tar‚ petrol‚ butane‚ and methanol etc. Their manufacturing process can be understood as follows: Crude Oil

Carbon also can be found abundantly distributed in a nonliving environment‚ in the atmosphere as Carbon Dioxide (CO2)‚ natural gas‚ dead organic matter and coal in the ground.

The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems. Indoor air pollution and urban air quality are listed as two of the world’s worst pollution problems in the 2008 Blacksmith Institute World’s

INTRODUCTION Sustainable development is about human development where the use of natural resources aim to meet the needs of human beings while simultaneously ensuring that the environment is maintained. These needs must be met for present as well as for future generations. In other words‚ in order for human beings as well as the planet to survive‚ changes has to be made that will maintain the natural resources that is available. There is currently a trade-off between sustainability and economic

Overpopulation is excessive human population in an area to the point of overcrowding‚ depletion of natural resources and environmental deterioration. The three most negative impacts overpopulation on the environment are water pollution and overconsumption One of the major sources of water pollution is organic pollution‚ which is becoming

Depletion of Natural Resources: The effects of overpopulation are quite severe. The first of these is the depletion of resources. The Earth can only produce a limited amount of water and food‚ which is falling short of the current needs. Most of the environmental damage being seen in the last fifty odd years

However‚ nuclear energy is considered as more reliable compared to other sources of energy. Moreover‚ energy sources can be classified as renewable and non-renewable sources of energy. Renewable energy sources are those which can be reused without depletion. Consequently‚ they cause less harm to the human health and less pollution to the environment. Wind energy is the energy from the wind and it is one of the best sources of renewable energy. Wind turbines are required to generate electricity. In addition

When we regenerate energy from natural resources like wind‚ sun‚ water and other non biodegradable substances we feel proud but when the consequences lie on ozone layer depletion‚ radioactive radiation make us afraid.
