After we read about all the things about the global warming, we understand how we affect planet`s health. We know that global warming is majorly cause by greenhouse gases. Greenhouse gases are gases in the atmosphere that absorb and emit radiation within the thermal infrared range such as chlorofluorocarbon (CFC) and many more.The process of the global warming is simple. When visible light from the Sun hits the earth, it passes through the atmosphere, hits the earth, and warms the earth. The earth emits some of this energy back out into space, keeping the planet cool. But the energy we emit is in the infrared, and some of that is absorbed by greenhouse gases in the air instead of going back out into space. When that happens, the air gets warmer - and the planet as a whole gets warmer too.
There are so many causes that can cause global warming. We can divide these causes into two major branches. Natural and Anthropogenic (Man-Made) .The example of natural cause is the release of methane gas that is dangerous to our environment and it is released when bacteria break down organic matter under oxygen-starved conditions usually happen at landfills. The most popular causes that contribute to global warming are man-made causes such as pollution, population, transportation waste, deforestation and many more. All of these causes mostly give off a green house gas called CO2 which is harmful to human being if it is in excess amount.
The effect of global warming upon us is very obvious. One of the effects is the rise in sea level. It is cause by the melting of ice sheets and glaciers, adding water to the oceans. Next are changes in regional climate and agriculture. The number of extremely hot days is likely to increase and the number of extremely cold days is likely to decrease. Droughts will increase in some areas and flood in others. The next effect is change in ecosystems. Rapid, continuous increase in temperature could lead to the extinction of many species and will change the entire ecosystem and maybe this could lead to human extinction too. Human health will be affected by global warming too. If global temperature increase, people living in locations where temperatures are already hot are likely to experience more stress and heat-related health problems than are people living in milder climates. The last effect of global warming we can discuss here is effect on stratospheric ozone layer. Global warming has caused a warming of near-surface air and it has caused a cooling of the stratosphere. The cooling of stratosphere layer will increasing the rates of chemical reaction that produce and destroys ozone layer. There are laws to prevent the global warming from becoming worst from time to time. First is Kyoto Protocol which is their main issue is to fight global warming. The goal of this protocol is to achieve "stabilization of greenhouse gas concentrations in the atmosphere at a level that would minimize dangerous anthropogenic interference with the climate system”. The second law is The Montreal Protocol. It is a landmark of international agreement designed to protect the stratospheric ozone layer. Montreal Protocol stipulates that the production and consumption of compounds that deplete ozone in the stratosphere--chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform--are to be phased out by 2000 (2005 for methyl chloroform).
