Describe the effects of global warming in light of the above statement .
I really need the answer .... so someone help by giving me examples other than the vehicles which cause air pollution.
thank u :)
Part of what makes this particular problem so challenging is that when Western nations began the process of industrialization, there was little in the way of environmental awareness. Factories polluted and businesses dumped much of their product in the environment as the desire to keep and make money overrode all. In the heightened sensitivity that we now have towards the environment, economically developing nations sense a double standard in play. It was socially and politically acceptable for industrialized nations to engage in economically sound, but environmentally challenging practices, which are now being discouraged by those same nations. One can argue that we, as a people, have become wiser and more understanding about the implications of this situation. Yet, nations who wish to compete might not see it in that light.
In addition to the points the previous two posters make, you can look at the technological advances in agriculture, medicine and other areas as helping lead to the main cause of all this--too many people. When countries can feed more people, and those people live longer due to medical advances, the population grows--exponentially. It wouldn't matter so much what humans were doing if there weren't so many of us. We enable more people to live, and they produce more pollution.
I totally agree the the previous answer.
But you could quote some countries such as China, one of the world largest energy consumer which also happen to be one of world's most polluted country.
However, in view of the serious consequences, China has started promoting research and development in the clean energy sources industry. (Go check Newsweek's article on 'everything u know about china is wrong')
As they start to realise the significant impacts on their people "Public health is reeling. Pollution has made cancer China’s leading cause of death, the Ministry of Health says. " (http://www.nytimes.com/2007/08/26/world/asia/26china.html)
There are environmental problems such as unpredictable weathers, hotspots that may endangers species, South America, in exchange for economical progress or Europe, Mediterranean Basin. Also, tourism and agriculture may have worsen the situation. (http://www.biodiversityhotspots.org/xp/hotspots/mediterranean/Pages/impacts.aspx)
Hope it's of some help! But it seems a little out of point and pardon my command of english. Moreover, it's a question on technological advancement, not economical advancement, hence, you must make a clear link between them.
Technological advances have definitely benefited us in form of more of material benefits and conveniences like sufficient food, clothing, housing, health care. People today are much better fed, clothed, and housed. People need to work less harder, and don't need to expose themselves to many perils that their ancestors hundreds or thousands of yeas back were.
But along with such gains in physical convenience and wealth, there have been some losses also. One are of loss has been the degradation of our environment. We have already lost a lot in terms of wiping out from the face of this earth many species of plant and animal life. Also we have damaged the natural beauty, serenity, and healthy environment of many places by industrial activity, urbanization, and mass invasion by tourists of places of natural beauty. A lot of such damage was unavoidable. But perhaps a lot more was the result of human callousness and excessive greed for profit rather than unavoidable outcome of technological development.
The damage that has already been done is great, but much greater damages now stares in our face in the form of global warming. This phenomenon, which is the result of excessive release of some gases such as carbon dioxide and ozone in atmosphere due to industrial activity, is slowly increasing the average temperature around the globe. Since 1800's global warming has increased average global temperature by more than 0.6 degrees, and is increasing further rapidly.
To a layman this increase in temperature does not appear to matter much, but if allowed to continue this way, it will cause mass extinction of plants and animals, and cause many other disastrous damages to the earth which will be irreversible. This means that bringing back the temperature to the original levels will not be able to reverse some of the effects of global warming. For example, one of the effect will be melting of the icecaps in the polar region, raising the level of waters in ocean. This process is irreversible after certain level of temperature is reached. Unless we are able to stop the global warming, the melting of ice caps will submerge under water coastal areas all around the world. This area is home for about 15 percent of the world population today.
Thus global warming is a very serious global problem which needs to be tackled at global level with cooperation of all the countries in the world.
