Human activity is the main cause for global warming. We are slowly killing ourselves, and this

needs to change! Every time we use our improved form of transportation such as a vehicle we

are releasing fossil fuels into the atmosphere. Another problem is that not only humans are

being effected by global warming. Animals are too! As the earth heats up the sun absorbs more

water, causing the lakes and rivers to dry up, leaving no water for animals to drink. Last but

certainly not least there has been no applicable chance in solar output within the last two

decades. Therefore scientists are able to prove that humans are the main cause.

Driving a car is the most air polluting act an average citizen commits. Air pollution is not a good

idea for a variety of reasons, large and small. Cars in the United States emit about 300 million

tons of carbon dioxide into the atmosphere each year. Overall, cars account for roughly 41

percent of the average person's negative impact on the Earth. Releasing fossil fuels into our

atmosphere is eating away at our ozone layer bit by bit. Although this is a huge convenience to

society, this act gis creating an unhealthy environment. Without a healthy environment, there

will be few or no healthy humans.

Animals will also have a hard time with surviving this horrible tragedy that we have brought upon ourselves. Sure its "just a pop can" but this simple gesture of littering that humans tend to

do on a daily basis is risking the animal's lives. Littering is one of the most common human

activities that harms our environment. When we drop that one piece of garbage on the ground,

it takes about 10 years for it to completely decompose into the earth. Even something as

commonly used as hairspray, is contaminating our atmosphere. The ozone layer gets thinner

therefore making the earth get hotter. When the Earth heats up, the sun absorbs more water

from lakes and oceans. If all the Earth dries up then the animals; and not to mention us humans

won't have anything to drink. So, our

Global Warming Paper Cameron Conolly For years many people have believed that we are causing the Earth to warm up faster. Global Warming is the heating of the climate. Others believe it is due to natural climate processes. Either way, we know that Global Warming is a serious issue for our Earth. One of the reasons we think Global Warming is occurring is because of Orbital Variations. “Orbital Variations” is part of a theory developed by Milutin Milkankovic. An astonishing fact about Milankovic…

Global Warming Jenny Mallory Argosy University Rise of Modern Science Following years of debate publicly on whether global warming is due to natural activities or is the result of mankind, evidence suggests that extreme climate and weather changes are caused by humans. Over the years, the earths’ climate has wavered many times, from periods of record breaking heat to the ice ages. Changes in the sun’s force and the earths’ course around it, along with natural elements such as; erupting volcanos…

GLOBAL WARMING Global warming, also called climate change, has become a topic of concern over the past decade. Climate has changed drastically over the past decade, “From 2001 through Feb, 2011 the atmospheric carbon dioxide increased by 22.2% of the total increase from 1800 to 2001” (Pangburn). Although I wasn’t completely aware of global warming and it’s circumstances until recently, I can honestly say that it is a issue to be concerned about. Global Warming is an indisputable…

Essay on global warming

GLOBAL WARMING: NATURAL OR MAN-MADE There is no question that there is an increase in Earth’s temperature and we are experiencing what is referred to as global warming. The Earth has experienced this many times in history on a much larger scale, but, humans did not exist (and would not have been able to exist) at the time. The questions now are whether human actions are accelerating the process of global warming and possibly decreasing Earth’s future sustainability; and, if so, what, if anything…

Essay on Global warming

What Are the Causes of Global Warming? What is global warming? According to NASA Earth Observatory, global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed…

Persuasive Global Warming

Global warming is the gradual heating of Earth's surface, oceans, and atmosphere. According to the Environmental Protection Agency, “Earth's average temperature has risen by 1.4 degrees Fahrenheit over the past century.” Sadly enough, “temperatures are projected to rise another 2 to 11.5 degrees Fahrenheit over the next 100 years.” As a consequence, global warming has emerged to have one of the biggest environmental issues in the last two decades. For the past years, scientists have been struggling…

Global Warming: Rodriguez Tony P.3 Global warming is caused primarily by carbon dioxide from burning coal, oil and gas. Certain gases that trap heat are building up in Earth's atmosphere. The primary culprit is carbon dioxide, released from burning coal, oil and natural gas in power plants, cars, factories, etc. (and to a lesser extent when forests are cleared). The second is methane, released from rice paddies, both ends of cows, rotting garbage in landfills, mining operations…

Global Warming Essay

endless debate going on about global warming. Some people say that global warming is a threat to us socially, economically, politically, and immediate actions should be taken to minimize it. Whereas, other people say that global warming is beneficial and is a natural process that is required for the sustainability of life on earth. Hence, in my opinion, global warming is a potential threat that causes harm not only to humans, but also to the planet as a whole. Global warming can be defined as the increase…

Global Warming. Is it caused by us? “…Climate change is now with us. It will not go away.”(Musil, 17) Many of us have noticed that our Earth is getting warmer. We seem to ignore what is going on and just continue with our everyday life. There is evidence that our climate has been getting warmer ever year. Some scientist believe it is because of green house gases. Green house gases include the carbon dioxide from gases that our industry produces, methane gases that cows put off, and some believe…
