Opinion Essay Draft

In this essay I'll be presenting and answering a very particularly question of contamination: Is global warming the most significant environmental problem facing us today? And my answer is no.

For so long, we humans have caused so many disasters that finished by destroying the Ozone layer. In these disasters we can find fires, oil spills, cutting down forests of trees, etc. In addition, according to nrdc, in the United States , electric power emits  more than two billion of tons of carbon dioxide each year. Global warming directly affects us on everything we do and unfortunately every single actions we do produce contamination, that's why we have to learn to deal with it but what we can do is to produce much less contamination by using green and renewable energy.

Moreover, according to the Union of Concerned Scientists, "not only are global warming-induced changes currently underway , and the climate hot map arranges current and future climate impacts into   5 main groups: People, Freshwater, Oceans,Ecosystems and Temperature. Inside this groups we can find very important elements such as temperature and ourselves, people".

And yet , people still think the opposite, such as Bernard L. Weinstein at national journey.com. "One can think of at least a dozen more dangerous phenomena that could destroy us long before growing greenhouse emissions cause the oceans to rise and species to die off" (2013)

In conclusion, I seriously think that we have to take care of our environment, because in the future we could possibly face and increase of temperatures from the coldest places to the tropical and desertical   zones of our planet Earth. Years before, we were afraid of global warming and its consequences, and now it became true, such as the melting glaciers in the north and south pole, as I mentioned before, the ozone layer, etc. Not forgetting our health, as we know, the sun rays causes skin cancer, that's why we have to protect our skin with sun screen and with sun glasses for our eyes. So I will end ny saying that we really have to consider the global warming and finish with air pollution, heavy sun rays, melting glaciers and the most important, the danger of our planet.

In the United States, electric power plants emit more than two billion tons of carbon dioxide each year, or roughly 40 percent of total emissions. The nation's landmark air pollution law could cut that number significantly.

Not only are global warming-induced changes currently underway, but scientists also expect additional effects on human society and natural environments around the world. Some further warming is already unavoidable due to past heat-trapping emissions; unless we aggressively reduce today's emissions, scientists project extra warming and thus additional impacts.
The Climate Hot Map arranges current and future climate impacts into five main groupings:
  • People
  • Freshwater
  • Oceans
  • Ecosystems
  • Temperature
Each of these major groupings, in turn, is divided into specific categories that describe more fully some of the consequences we may face. Click on any of the categories listed on the left for more information.

America Can Lead by Example
Global warming from the burning of fossil fuels is not the planet’s biggest problem. One can think of at least a dozen more dangerous phenomena that could destroy us long before growing greenhouse gas emissions cause the oceans to rise and species to die off. But that’s not to say we shouldn’t be
concerned about climate change.
The best way for the United States to “lead the way on a comprehensive, international approach to addressing global warming” is by example. GHGs in America are lower today than 20 years ago, even with an economy that’s 50 percent larger, mainly because we use energy more efficiently. Today, we can produce a dollar of GDP with half the energy input required a few decades ago. At the same time, we’re substituting clean-burning natural gas for coal in power generation and industrial boilers. We could further reduce GHGs by developing the infrastructure to fuel more of the country’s 300 million motor vehicles with compressed natural gas (CNG) and liquefied natural gas (LNG).
