Global warming has been a highly debated topic for quite a bit of time now. Is it or is it not happening? Global warming is an increase of temperature that causes related changes in climate and the environment. This has been seen in Antarctica especially. The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already.
33% of the carbon dioxide comes from vehicles. “Vehicles with poor gas mileage contribute the most to global warming”(Ayers) It is
Since the temperatures have started to rise, the ice that they once lived on has melted and they are having a very difficult time surviving. People have increased the temperature of the Earth by contributing their pollution. Burning fossil fuels and forests has been the biggest issue amongst us all. Simple changes could help in simple ways but the fact is that since it is a global issue, the world has to be involved in order to make a difference. The United Nations has contributed in this way by holding meetings to discuss the climate changes throughout the world and what can be done to help.
Since we have the attention of everyone, now is the best time to take action against global warming. Due to the increasing temperatures every year our public health and our agriculture/food supply is at high risk for new and worse diseases due to global warming; we need to change our climate control policies to protect ourselves. Gases are being trapped inside of earth’s atmosphere like a soda can, and are gradually increasing Earth’s temperatures that ice will start melting and there will be flooding due to rising sea levels; plants and animals will start becoming endangered (as cited in Cooper, 2001). We have already seen coastal flooding in parts of Central America and Bermuda’s forests are now endangered due to flooding (as cited in Clemmitt, 2006). Global warming has been an issue since factories were introduced to this world; gases and toxins are being highly exposed into our atmosphere causing a tremendous reaction to the balance of nature.
As Williams E. Rees states in his book “Our Ecological Footprint”. This is shown in the Climate Change view because our pollution results in temperatures rising. Due to this increase of temperatures the Arctic sea ice is melting, glaciers are retreating and sea levels are rising. At the top of the food chain are the producers. In society’s case the producers are the natural resources.
The deglaciation of ice sheets and glaciers, which happens when we enter a interglacial warming period, are important because they have an immense impact on the land structure and vegetation throughout our continent, as well as the rest of the world. The deglaciation of the Wisconsin Glacier caused the formation of the Great Lakes as well as Niagara Falls in New York. This melting of ice sheets also causes sea levels to rise which covers landforms. The water submerges bridges and passageways between continents that were used by animals which migrated from continent to continent. This prevents certain species of mammals and plants from returning back to their native land, which drastically changes the vegetation and habitat of certain areas.
The 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment. The film cites many recent climate change and natural disasters. Throughout the facts, we see that human life must depend on the natural environment. According to Thom Hartmann, “We are a part of nature. We can’t separate from nature.” As DiCaprio tells us we cannot survive without nature.
Banning the Use of Cigarettes The ban of cigarettes is an ongoing debate in many states. There are currently 25 states and DC that have smoke free laws ("25"). Cigarettes are one of the top killers in the United States and all over the world. Just in the 21st century alone there have been 1 billion deaths due to cigarettes (“Tobacco”). Cigarettes are also one of the top purchased items in the world.
And for that moment I wished it was me on that bike because I was late for work. The way gasoline prices are going up all over the world, biking to work instead of driving will be the best way to offset the rising cost of gas, and also to avoid getting stuck in traffic. According to Michael Bluejay, an award winning writer of “The seven- best on the web! “Automobiles are the second largest source of carbon dioxide (CO2) pollution in the U.S. They create nearly 1.5 billion tons of CO2 each year”.
“But by 2030, it is estimated world CO2 emissions will be 63% higher than today, as global demand for energy grows.” (Source 5: http://news.bbc.co.uk/1/hi/sci/tech/4216302.stm BBC produced website showcasing an article written by a specialist in environmental issues. Concerning the above fact, that nuclear energy provides CO2 as does the use of fossil fuels, this fact shows that as the world asks for more energy, our energy sources will have contributed highly to global warming regardless of being nuclear or not. It shows that by 2030 carbon emissions will be immensely higher than today as a result of fossil fuels today and existing nuclear reactors.) “1/4 of the country’s (Chernobyl) best farmlands and forests have been poisoned for hundreds of years by Caesium 137 and Strontium 90.” (Source 6: http://www.chernobyl-children.org.uk/disaster.html a website produced by a
