-poor farming practices
-natural disasters
high populations
-any other areas

I chose global warming and natural disasters.

We are living in the world where almost every part is polluted. Humans and animals are suffering from the effect of polluted planet. When we look at this into more closely, ironically, we find that the consequence is led by the very us. With a process developing industries, we allowed tons of greenhouse gases release into the air, which are leading to the increasement of temperature in the planet, attributing to the natural disasters as well.

The processes of burning fuels are aggravating the global warning. To develop industry for the better standard of living, the process of burning fuels are inevitable considering there are no other alternative sources except coal and petroleum at the moment. Carbon dioxides, the main culprit of global warming, are exhausted from various places and vehicles such as power plants, buildings, cars, and planes. Emission of methane, which are about 60times more effective than carbon dioxide in trapping the heat inside of our planet, emitted from livestock is also partly, but not least, contributing to the global warming. That is to say developing economically alternative resources and focusing on cutting down the above two main greenhouse gases is impending.

The consequence of the global warming is serious than general recognition. Noticeably, the process of melting down glacial is speeding up as temperature of the earth keep rising, which goes directly to the raised sea level. Experts say that even a small rise of the sea level will result in wiping out the whole nations and their culture that have existed for thousands of years (Jonathan Overpeck, 2009, 08, 25). The rise of temperature on the planet also results in extending the range of mosquitoes that spread malaria, which would also annihilate the whole nations of developing countries, not to mention the poor ones. Thus, while some are blessed with industries, others are suffering from the leftovers on the other side of the earth.

Then natural disaster follows in various forms. The heated earth leaves dreadful droughts and aggravates desertification, and even provokes tsunami more often, which results in broad range of famine and disease (David Roberts, 2009, 08, 25). In addition, Limnic eruptions, in which carbon dioxide suddenly erupts from deep lake water, are occurred more often than usual since slight increase in temperature would easily trigger the eruption, suffocating human, wildlife, and livestock.

At the same time, the natural disaster caused by greenhouse effect have brought bad effects on the economy. According to the department of energy in USA, investing 1 million dollar to spur biofuels industry ended up as 4% of increasement in the price of corns (Department of Energy, 2009, 08, 25). What's more, Longer summers have led to an increase in the allergy season and increased health care costs for asthma and allergy sufferers. Therefore, at this angle, it can be said that the efforts trying to go ahead in economy rather drew back in some level.

In a nutshell, humans are bringing about the consequences from which humans itself suffer. In the long term, burning off fuels in trying to grow up the industry for the better economy are merely strangling us by raising the price of the corns, provoking wide range of natural disasters and polluting our very planet. Even though it's not early stage to prevent some natural disaster given the fact that the earth have already shown the strange symptoms of global warming, we are to continue to endeavor in seeking for alternative resources and should try to start in posing environmental issues before economy's.

Any correction or commenting would be appreciated. Due to my shortness of knowledge in english, my sentences tends to be long in length. If you have anysuggestion on this, that would be also very welcome

thank you.

Good work, really, but, the causes of global warming might be more complex. Some are due to human activity, but some are not. Policies, people' attitudes toward pollution, will also influence the causes and effects of global warming as well as natural disasters. More complete analysis will make this essay stronger.

You should be sure to explain what glacial ice caps you have in mind, here. A lot of the Arctic ice is melting at the moment, but this doesn't raise sea levels, anymore than a melting ice cube raises the amount of water in your glass (the ice already displaces water equivalent to its volume.) Some of the Antarctic glaciers have been crumbling, and the melting of the Antarctic ice caps would raise sea levels (because that ice is on land, and so is not already displacing sea water) but the glaciers that crumble on the southern tip are so far not enough to offset the additional ice building up elsewhere in Antarctica. That is, the total amount of ice in Antarctica is increasing, not decreasing. I believe there is an icecap in Greenland, though, that could influence sea levels if it were to melt, and that is actually shrinking, though you'd have to do some research to verify that. Also, warmer water expands, so if sea temperatures rise, one would expect sea levels to rise also. You might also want to look at where sea levels have been in the past, to determine if a rise would be an abnormal freak of global warming, or a return to traditional norms.


Bad choice of example. We know how to eliminate malaria, as evidenced by its disappearance from North America and Western Europe. The world has chosen to permit the disease to continue to exist, by banning or severely limiting the use of DDT. Western environmentalism has trumped the world's concern for developing people's health, but that isn't an effect of global warming. I'm sure you can find other tropical diseases that would be spread by global warming to mention, though, that would be less ironic in a piece written from an environmentalist standpoint.


A mixture of oversimplifications and outright falsehoods. Tsunamis are caused by earthquakes and volcanic eruptions. They are not caused by global warming, or anything affected by global warming, and not even the most dedicated global warming doomsayers make such claims. Some do argue that a variety of human activities have eliminated the plant life that would normally act as a barrier against tidal waves, and so have made the effects of tsunamis worse than they would otherwise be. A warmer earth presumably would lead to droughts in some places, but it would arguably extend the growing season in many others. Indeed, global warming would likely benefit large sections of Canada and Russia, for instance.


In the long-term, we're all dead. In the short and medium term, the massive benefits of modern technology greatly outweigh the environmental drawbacks. Most cost-benefit analyses show that it would be far cheaper to adapt to global warming and continue our current lifestyle than to try to prevent global warming. Geoengineering solutions are also being taken increasingly seriously as scientists realize that, if climate change really is a problem, then the only long-term solution that will work, given that the climate has always, from the beginning of the planet, been in a state of constant flux, is to turn the climate into something that is wholly controlled by human technology.

Overall, your essay, especially for a research paper, needs a lot more depth. You do little more here than regurgitate green groups' talking points that you could have picked up without doing more than a cursory internet search on the topic. Your thesis is defensible, but you will need to show that you have read about your topic in far more depth, and write about it with a great deal more nuance, than you currently do.

Thanks both tsp8487 and sean.
obviously I need more research, and have to have more clear view on this.
thank you.
Is there any grammer mistake in this essay?

You say that this is a research essay. If your sources support the statements that Sean has challenged, your statements can stand, provided that you adequately state and accurately represent reliable sources.

The statements that aren't patently false can stand, though you should probably elaborate on them and provide suitable qualifications that allow you to avoid dramatic oversimplifications. To this end, you might want to cite more than three sources. You should probably consult a variety of sources from a variety of perspectives, at least some of those sources should be actual books, rather than online sources (though you can use Google Books to access full texts online). A research paper is only as good as the research it draws upon, and you don't seem to have done enough to be able to discuss the issues in sufficient detail.

Thanks for the advices ^^

In the long term, burning off fuels in trying to grow up the industry for the better economy are merely strangling us by raising the price of the corns, provoking wide range of natural disasters and polluting our very planet.

Don't write corn. Corn is not only used for biofuels, there are other crops being used as well. Instead, you could write price of food. It makes the reader more "scared". :P
