The world is in our hands. |
These days the earth was hot. What really happened? Much of motor vehicles and factory smoke causes air
pollution. The gas increase carbon dioxide concentrations
in the atmosphere. Carbon dioxide is one of the factors which causes
greenhouse gases. Greenhouse gases such as CO2, CH4, N2O, SFG, stuck in the
earth's atmosphere, so that sunlight can not be reflected back out of the
earth, so that the earth is hot. It is also
caused by human behavior. Forest which serves to absorb CO2 are cut, so that the concentration of O2 gas is reduced. These things causes the earth’s temperature are rises. This is usually called global warming.
What are the effects of global warming? Global warming causes climate instability. Hot temperatures can also causes harvest failures that so will result to hunger and malnutrition. This will also impact climate change is causing certain diseases such as respiratory infections.

Drought causing harvest failures and difficulty to get clean water. |
Second, the increase of
global temperatures are melting of arctic ice
is causing rising sea levels. Sea level rise could sinking of the small islands.
Where they will live?
Third, global warming could have an impact on the
ecosystem damage that increases the risk of spread of waterborne diseases and vectors disease. Such as dengue fever since the advent
of ecosystem new breed mosquitoes.
Fourth, the reduced species of animal on earth. The
researchers said, climate change could disrupt the food chain, where the top predator
in the food chain are the most affected due to the decline population of the prey.
Fifth, in economics and politics, global warming
causes emergence of terrorists because of the instability of poor countries led
to the migration and
monetary crises.
What should we do to anticipate global warming? We can do small things like
turning off electrical appliances when not in use, replace light bulb with a
fluorescent lamp, use bicycles to reduce pollution, saving
paper usage, reduce the usage
of plastics and recycle the plastics, reforestation, planting trees to reduce CO2 levels in the air. And become a
vegetarian.
with bicycle we health and can reduce the air pollution. |
