global warming

There has been a considerable increase in the average temperature of earth in recent years . This phenomenon is called Global Warming. The effects of global warming are numerous and various, ranging from the effects to the atmosphere, environment as well as the health life of human beings and animal. Three main effects which global warming leads to are climatic change , extinction of species and diseases.
Firstly,one of the major effects of global warming is the climatic change that is being absorbed on the earth. There are floods in the areas where the flood history is not very common.For example, in Cambodia, people have experienced unpredictable floods in last three years. There are droughts in places, which were having good rainfall.For example, in Australia. The atmosphere gets suddenly very harsh . The nature of earth's atmosphere is becoming even more unpredictable . This in turn brings about a variation in the biological systems essentially the crops, forests, oceans, fresh waterways, and grasslands. As these are the building and breeding grounds of life, the life on earth is getting affected.
Secondly, the effect of global warming is very evident on the animal kingdom also. Some animals have become extinct due to loss of their natural habitat or their inability to evolve to the rapid changes in the climate. Also, there is a change in their life style because of the changes in the seasons. The migrating birds have changed their time of travel and also their place of migration. Global Warming has been noticed in the behavior of the wild life. Major changes are seen in the animals as they react to the warmer environment, which are caused due to global warming. For example, many fish species are moving northward in search of cooler waters.
Lastly, the global warming is also responsible for the introduction of some new diseases. The bacteria are more effective and multiply much faster in warmer temperatures compared to cold temperatures. The increase in temperature has led to increase in the microbes that cause diseases. A warmer world seems to be producing a sicker world. Global warming is particularly hard on people in poor countries because the places that have contributed the least to global warming are most vulnerable to the death and disease higher temperatures can bring . Many of the most important diseases in poor countries, from malaria to diarrhea and malnutrition, are highly sensitive to climate.
In short, global warming is a threat to our future because it brings out many consequences such as climatic change, extinction of species , diseases……So, we should do something to reduce global warming such as cleaning up air polution, saving money with energy…..so that we we have a comfortable living environment .
