 ozone layer  ozone layer: Ozone the stratospheric ozone layer is normal part in the earth atmosphere that absorbs High-frequency ultraviolet rays and protects us form their damaging effects. In contrast ground level ozone is an air pollutants, which has harmful respiratory and cardiovascular effect. Ground level is largely the result of UV photosynthesis of NOx and VOCs .( Product of vehicular and industrial combination). the ozone layer or ozone shield is a region of the upper atmosphere between roughly above earth surface containing relatively High concentration of ozone molecule (O3). The ozone layer form a thin shield in the upper atmosphere protecting life on earth from UV rays. Ozone is a naturally occurring gas that is found in two layer of the atmosphere.In the layer surrounding the earth surface the troposphere ground level and bad ozone is an air atmosphere to urban smog. The troposphere extends up to the stratosphere which good ozone protect life on earth by absorb...

 Noise Pollution What Is Noise Pollution? Definition Noise pollution is generally defined as regular exposure to elevated sound level that may lead to adverse effects in humans or other living organisms. According to the World Health Organizations sound levels less than are not damaging to living organism regardless of how long or consistent the exposure is Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardou. If you work for 8 hour daily in close proximity to a busy road or highway you are very likely exposed to traffic noise pollution around 85dB. noise pollution noise pollution is the propagation of noise or sound with ranging impacts on the activity of human or Pollution is one of the main concerns, the world is dealing with amidst all the problems and issues. However most of the time it is air pollution and water pollutions that is spoken about. The limelight may not be on Noise Pollution but it also has tremendou negative effect. Noise is a word that ...

 Soil pollution   Human activitie are the primary case of the soil pollution and land degradation. By the end of this topic. You will know how different form of human activities are responsible for the majority of different Type of soil pollution  1. what is soil pollution ? soil pollution is defined as the presence of toxic chemical in the soil pollution in very high concentration to pose a risk to human health and the ecosystem or in simple word alteration in the natural soil due to the human activites is termed soil pollution. for example exposure to soil containing high concentration of  benzene can increase the risk of soil pollution.all soil contain compounds that are harmful to human being and other living organisms. the concentration of such substances in unpolluted soil is low that they do not pose any threat to surrounding but when the concentration such substances becomes high enough to cases damage to living organissm the soil is sad to be contaminated. S...

As per environment act,1986, environment included all the physical and biological surroundings of an organism along with their interactions. Environment is thus defined as the sum total of water,air and land and the interrelati-onship that exist among them and with the human beings,other living organisms and materials. SCOPE  Environment studio as a subject has a wide scope. It encompasses a larger number of areas and aspects, which may be summarized as follows: Natural resources - their conservation and management Ecological and biodiversity Environmental pollution and control Social issue in relations to development and environment Human population and environment Important of environment  For millions of years,nature provided us everything to live a batter life and start from cloths, food, lights, air to beautiful landscapes, waterfalls and forest. H...

Air pollution    1.What is Air pollution?        Air pollution is a common problem in our country and air pollution dengerous chemical for example carbon monoxide, hydro carbon etc. the produced by human activities such as the using of vehicles ara produced by human activities as the vehicle which produce smoke causing the air pollution and factory activities such as the using vehicle which product the tires and fake animals skil which use fuels and machine that trigger the air pollution. Plants can reduce the air pollution by produce the oxygen which is very important and human body life to breath. Plant can also absorb the carbon dioxide by their leaves. They need the carbon dioxide. That is why they absorb the carbon dioxide and course plants help us to reduce the air pollution. The second solution is that the government should be give clear rules for the industry which use fule and machine causing the air pollution. The first rule is that industry shoul...
