science into banes. It is said that science is a good servant but a bad master. 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. I think it’s truly said that good and evil are two sides of a same coin as on one side it has made our life comfortable and easy and also we cannot ignore the other side that science made factories

The chlorofluorocarbons which come from aerosol sprays nuclear weapons‚ refrigerators etc.‚ have caused a hole in the ozone layer of atmosphere. This hole is allowing increased amount of ultraviolet radiation reaching our earth. The above mentioned factors have really degraded the environment and if ways to check it are not applied we will have face serious consequences

Depletion of Resource Nowadays‚ world population is increasing ‚ this will affect the depletion of our natural resource. Large population increases in the developing world will strain resources and agricultural productivity (Eicher‚2008) .For Instance ‚ as populations grow‚ it may be necessary to convert additional land for agriculture housing development‚ and infrastructure. However‚ we need more products for our daily basic needs or extra needs for the upper class people . When high consumption

The Earth’s ozone layer is supposed to protect people from the Sun’s harmful ultraviolet rays‚ but in the 1970s‚ scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen‚ which means that more ultraviolet rays reach the Earth. During the 1980s‚ scientists found that the ozone layer above the South

The social practices conducted in society are harming the environment in many different ways. Pollution destroys the air as well as the ozone layer‚ but the societies don’t think about the consequence of their actions on future generations. Pollution is the introduction of contaminants into a natural environment that causes unsteadiness‚ disorder‚ destruction or distress to the ecosystem

My views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously‚ nor do I believe that the earth is so delicately balanced. I don’t believe that the earth and its ecosystem are fragile. Many radical environmentalists do‚ they believe man can come along‚ all by themselves and change everything for worse. After hundreds of millions of years‚ they believe that we are the last two generations of human existence. And they think we can destroy

on the air conditioner‚ we use Freon gas and when this Freon gas goes up to the Stratosphere where the Ozone layer is. And that Freon gas destroys the Ozone layer‚ so by that‚ we get more harmful ultraviolet rays from the sun that can cause our skin old or even cause skin cancer. So‚ I suggest that we should take buses when we go to somewhere not that far away because it actually helps our Ozone layer. Secondly‚ we have soil pollution. I think when farmer uses agricultural chemicals to their crops
