Nowadays, we are facing with one of the biggest problems for the mankind, called global warming. This problem is explained as increased amount of carbon dioxide in the Earth’s atmosphere. As a result of this temperatures are rising. As a consequence we should expect climate changes which will change our lives forever. From this point we will be witnesses of:
Ø Rising of sea level;
Ø Frequent appearance of hurricanes;
Ø Frequent and intense heat waves;
Ø Extinction of a different species of animals.
But, we should be concerned about impacts of global warming on our health. We all are aware of the fact that the prevalence of some diseases and other threats to human health depend largely on local climate. So, extreme temperatures can lead directly to loss lives. Also, climate-related disturbances in ecological systems, such as changes of infective parasites, can indirectly impact the incidence of serious infections diseases. Next, high temperatures can increase air and water pollution which in turn harms human health.
In extend, to protect ourselves and the Earth from catastrophe we must be aware of the biggest causes of it. First we have carbon dioxide from power plants, from cars, from airplanes, from building. Next, major causer is methane which is derived from sources such as rise paddies, bovine flatulence, bacteria in bogs and fossil fuel production. Third, but not less is human activities. For example, cutting and firing forests, frequent use of cars, throwing waste improperly etc.
Finally, we have the causes and effects of the global warming. As part which is concerned we should do something to slow down this process. Things we can do:
Ø Plant trees as much as we can;
Ø Walk or ride our bicycles in stead of use bus or cars;
Ø Recycling all kinds of items;
Ø Turn of the lights, the radio, the TV and the computer when we aren’t using them.
This may be little for us, but huge for our mankind.
