The impact of global warming on the environment is extensive and affects many areas. In the Antarctica, warmer temperatures may result in more rapid ice melting which increases sea level and compromises the composition of surrounding waters. Rising sea levels alone can impede processes ranging from settlement, agriculture and fishing both commercially and recreationally. Air pollution is another problem arising from the use of fossil fuels, and can result in the formation of smog. Other than causing human illness, smog can also affect the sustainability of crops.
Smog seeps through the protective layer on the leaves and destroys essential cell membranes.
This results in smaller yields and weaker crops, as the plants are forced to focus on internal repair and do not thrive. When coal is burned, it releases nitrous oxide. Unfortunately this is kept in the atmosphere for very long time. The harmful impact of this chemical could take up to a couple of hundred years to make itself known. It is very difficult to prevent or to diminish an impact when you are not even aware of what it may be.
