What Are Emissions?


Emissions are defined as gases or other small particles that get into the environment when fuels are burned. Most of these come from automobiles and industries. When much of these are released in the atmosphere the air becomes of poor quality causing pollution and global warming. Humans contribute to emissions through air. Digestive processes of livestock contribute small portions of carbon dioxide and methane. Human beings release emissions as a result of their inventions. Some of the emissions include methane gas, hexafluoride, carbon dioxide and nitrous oxide. Another emission is ozone which results from combination of gases and air.

United states have the highest levels of emissions in the world. This is due to the high industrialization. Due to the technological advancements more and more countries are increasing their levels of emissions. Use of clean energy is the only solution that can facilitate decrease in the amounts of emissions that are getting into the environment. Clean energy is any source of energy that does not release toxic gases in to the environment. In addition clean energy sources are never exhausted and so they can be renewed. Examples of these sources are solar and wind energy. These two sources of energy are proving to be more and more popular and they are even more available and cheaper to consumers (UNEP, 2010).

The accumulation of green house gases in the environment causes the formation of ozone layer. This layer acts as a blanket that traps a lot of heat in the atmosphere which then results to changes in the climate. These changes in weather causes extreme conditions like floods, droughts, storms and also rise in the sea levels. Climate change has become a worldwide disaster. It has therefore become an issue of concern which if not prevented will cause destruction of conditions and resources around the globe. These changes have great impact on the lives of individuals.
