environment is the main issue. Today‚ increasing population growth causes the natural environment to change greatly. This paper focuses on the negative influence of population growth on the environment in these areas: air pollution‚ water pollution‚ global warming and ozone depletion. Air pollution is an important pollution problem. Increasing population growth creates more of this pollutant whose major source is burning of fossil fuel‚ larger number of vehicles and industrial production. As a result

This increase in global surface temperature is thought to have at least some effect on the frequency of extreme weather events due to climate changes (Folland et al. 2001)‚ and there is concern that these changes will have an enormous impact on various industries (Hitz and Smith 2004). Balancing environmental measures with economic development‚ that is‚ working toward sustainable development‚ is the fundamental goal of global environmental policies‚ including those for global warming (Hijioka‚ Masui

The three main areas to be explored are the relationship between ‘Greenhouse’ effect and global warming‚ the consequences of global warming with evidence and the argument against addressing global warming.

It forces one to think that humans are the major cause of this hazard. It encourages one to believe the fact that there are ways in which we can reduce the effects of global warming. On the other

Gore have very different views on the issues of global warming. Botkin contends that the scare tactics used by Gore and many similar thinking environmentalists are simply a desperate means intended to alarm the public and force governments to take actions that are unnecessary and misdirected. Gore alleges that immediate action is necessary to avoid increases in the plant and animal extinction and the spread of diseases. Botkin admits that global warming is a fact‚ but as a scientist‚ he cannot agree

Air Pollution and Global Warming SCI 275 Cheryl Wilson September 30‚ 2012 Tori Robinson Air pollution causes global warming through the greenhouse effect‚ according to the United States Environmental Protection Agency. The greenhouse effect occurs when greenhouse gases trap and heat energy from the sun and prevent it from escaping Earth’s atmosphere and entering space.” (EPA‚ 2012) Atmospheric pollutions are caused by gasses and solid particulates released into the atmosphere.
