Recommended: Impact of ozone depletion on people
The ozone layer is one of the layers of Earth’s stratosphere. The ozone layer absorbs radiation that hits Earth from the sun. Ozone is a good trapper of types of radiations such as ultraviolet radiation or UV light. UV light can penetrate organisms’ protective layers, such as skin, damaging organisms’ DNA molecules. Ozone molecules are made up of three molecules of oxygen atoms and it is always being destroyed and naturally restructured however, chlorofluorocarbons (CFCs), which is a nontoxic, nonflammable chemical that contains atoms of carbon, chlorine and fluorine, is harmful to the ozone layer. Chlorofluorocarbons are used in manufacturing of aerosol sprays, blowing agents for foam, packing materials and refrigerants. Other gasses also affect the ozone layer by causing a hole in the gas layer; this is called the ozone layer depletion. In my view, the ozone layer depletion is hence significant and we as Earth’s residents should prevent the constant expansion of the hole as it results in severe diseases and mutations in organisms. The ozone layer is vital because it filters harmful ultraviolet radiation and …show more content…
This thinning of the gaseous layer has formed damage near the poles. This damage is technically a hole in the ozone layer. As the ozone layer gets thinner; more ultraviolet waves reach the Earth’s surface causing much destruction to humans, animals, plants and other living organisms like plankton and bacteria. Another study by National Geographic on a forest in San Bernardino National Forest, California, pathologists examined a pine tree which is damaged as a result of a thin layer of ozone above the area. Furthermore, many people, in Seringapatam, India, suffer from skin damage and skin diseases caused by exposing to the sunlight and getting sunburned as a result of ultraviolet waves reaching the
While doing his research Molina learned that these compounds move up to the ozone and stay there. He expected the compounds to be destroy by the solar radiation. However to his surprise he formed that chlorofluorocarbons would simplify into component element when exposed to radiation. This simplify components produce a highly concentration of pure chlorine atoms. From there he already knew that the ozone layer can be destroy with chlorine.
It can kill you! Yeah, this thing is silent and deadly! Colorless and odorless, you never know where it can be leaking from. Can you smell? Nope! Can you taste it? Nahhh! Have you figure it out yet? The thing that might take your life right now, or maybe tonight or maybe tomorrow. No? Well, I’ll be nice and tell you. The poisonous demand that lurk through the air so free and careless is Carbon Monoxide or CO. In this paper, you will learn all what and how it can kill you plus how you can protect yourself from Mr.CO
As the twenty-first century progresses, it has become increasingly apparent just how many challenges the world faces. Prominent among these concerns are environmental issues, in particular, ozone depletion and climate change. While the international community has been exceptionally successful in its struggle to reduce the production and consumption of chlorofluorocarbons (CFCs), the organic compounds that contribute to the ozone issue, its efforts to tackle climate change have yielded considerably fewer advancements. A number of factors that helped the proceedings of the ozone regime, or campaign, are not applicable to the climate change regime. The issue of limiting CFCs was much less politically and economically charged than that of reducing greenhouse gases (GHGs), which cause the greenhouse effect and the consequent warming of the planet. Climate change has been referred to as the ultimate “tragedy of the commons”, an important metaphor in economics that helps explain why this subject is still at the centre of much heated debate and has yet to be resolved in a manner similar to that of the ozone problem.
“In 2008, 21,000 Canadians died from the effects of air pollution.”(Geduld) Although most of these deaths are from long term exposure to the pollutants there was still “2,682 deaths caused from short term exposure.”(Geduld).“5.5 percent of cardiopulmonary (heart and lung disease related) deaths can be attributed to ground-level ozone exposure, which has increased over the past decade.” (David Suzuki Foundation)
Pollution is affecting many individuals and life, as we know it. We need to do something about how it’s affecting our world. That’s why I urge the issue that more people should realize that pollution is an issue that needs to be prevented because of its negative consequences. Which are health affects, the total destruction of environments, and the death of animals and plants. More awareness must be brought up amongst the people and they must realize the long-term benefits it has for the world.
Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
Attention Getter: Most of the people present here today probably recycle; some more than others. And probably, most people assume that they are saving natural resources and helping the environment. However, this is not always true.
PURPOSE: To persuade my audience that we must take action now to control air pollution
Initial preview: We will learn about the creation of air pollution, the effects of air pollution, and how the companies reduce more air pollution from a catalytic converter.
In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found that human-made chlorofluorocarbons used for making foam, cleaning fluids, refrigerants, and repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for several decades due to their long tropospheric lifetimes. These compounds are carried into the stratosphere where they undergo hundreds of catalytic cycles with ozone.4 They are broken down into chlorine atoms by ultraviolet radiation.5 Chlorine acts as the catalyst for breaking down atomic oxygen and molecular ozone into two molecules of molecular oxygen.
Speaker Credibility: Has anyone seen the Documentary film called “An Inconvenient Truth”? I was amazed at how the earth was rapidly changing for the worse. This is why I choose this topic, to learn more about climate changes and inform everyone here about the climate change.

Hello everyone! Today I will be speaking about global warming but before I begin, how many of you believe that global warming exists and that the human population is the primary cause of global warming? I ask this because there are people who believe that global warming does not exist or that it’s “a hoax created by China”. But that’s not true and global warming is in fact one of the biggest problems facing the world today. There is a significant amount of negative effects for the environment and for all living beings due to global warming. And maybe some of you are not be interested in global warming, but the truth is, global warming is a big part of our world and it affects each and every one of us.
The problem I have chosen is the problem of endangered species. An endangered species is a group of organisms that have a risk of becoming extinct. More than 90% of all species that have ever lived on earth has become extinct. Many reasons for this are habitat loss, predators, too few organisms for sustainable reproduction. Habitat loss is the most widespread cause of species endangerment and extinction. Usually, this is happening because of human activity including deforestation and pollution. Pollution and climate change affect the ecosystem, resulting in rise of sea levels, melting of glaciers/ice caps, and pollution can cause death to many seabirds and and marine creatures living on the coast and in the ocean. Rising sea levels can
...rbon dioxide, hazardous chemicals, and other pollutants, which can put a hole in the ozone. Also, the usage of some mineral resources can also pollute the air; burning any kind of fuel fossils releases dangerous elements into the air, such as carbon dioxide and carbon monoxide. All of these kinds of pollution which are caused by the increase of technology, can lead to global environmental problems.
