Chlorofluorocarbon

Before the Toxic Substances Control Act was passed by the United States law in 1976, the human population was believed to have been exposed to a multitude of chemical substances and mixtures. These chemicals were beginning to cause a lot of health problems to humans. This caused the lawmakers to believe that among the substances that are being constantly developed and produced, there are some whose manufacture, processing, distribution in commerce, use or disposal may present an unreasonable…

direct air pollution. Eutrophication results from nitrogen in pollutants being developed over the sea 's surface. Eventually it turns into algae and affects all wildlife present. Depletion of the ozone layer is effected from hydro chlorofluorocarbons and chlorofluorocarbons. As the ozone layer worsens, this could potentially cause eye and skin…

Although this can be viewed as a controversial topic, the scientific evidence to support it cannot be logically argued with; the Earth and its climate are changing and legislation should broaden as this predicament processes. This claim is supported by a number of scientific findings that reflect negatively on the Earth’s environment. In response to this there is information on current and past legislation; as well as various opportunities the United States could participate in in the future.…

and take steps towards reducing greenhouse gas emissions. Global warming is “a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons(CFC), and other pollutants.”…

to Dorling Kindersley, "Industrial waste, sewage, and chemical pesticides from farms seep into streams and rivers. Cars, factories, and power plants burning fossil fuels give off fumes that pollute the air. Chemicals called CFCs (short for chlorofluorocarbons), used to make refrigerators and aerosol sprays, destroy the ozone layer, which protects us from harmful sunlight. Household and other waste buried underground pollutes the land." This shows that the advancements in technology and…

One of the greatest challenges of our existence in this planet is global warming. It is even a challenge for some to believe it, going so far as to call it a hoax. The rise of the average temperature of the Earth’s atmosphere is believed to permanently change our climate. The fact that Antarctic Peninsula being the most rapidly-warming part of the southern hemisphere, about 10 times faster than the rest of the world, impacting on the volume of water in the world’s ocean. It’s time to think of…

heats up water vapor increases as well as clouds and precipitation. Methane is a very active greenhouse gas produced by natural sources and human activities. Nitrous oxide is a powerful greenhouse gas produced by soil cultivation practices. Chlorofluorocarbons are synthetic compounds entirely of industrial origin. They contribute to the destruction of the ozone layer and are produced and released into the atmosphere for this purpose,…

In our solar system, there are the nine planets. They are Mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. These planets was formed when clouds of gas and dust collapsed with gravity in space. Earth is the third planet from the sun. Throughout the solar system, Earth is the unique place where life can exist. This planet contains atmosphere with oxygen, with lands and oceans on its surface. The ocean covers roughly 70 percent of the Earth's surface and besides that 30…

The oxford dictionary states that global warming is “a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants”(NASA 7). So to summarize due to pollution, the greenhouse effect and the high levels of CO2 our planet is getting warmer as time passes. Evidence. The way that our world normally works is that it receives its heat from…

Many people around the world are wondering what is happening with the changes in weather patterns. A scientist argues that human activity has affected the climate and this has led to a change. The issue of climate change is causing many counties, companies and people to focus on this issue. There are many reasons why global warming exists. The first has to do with the idea that humans are primarily responsible for global warming. Scientist think that human is the caused of global warming. Human…
