GLOBAL WARMING

Global warming is a popular topic nowadays. It is literally an increase in the Earth`s average temperature, in the near-surface air and oceans since the 20th century. It is bought by the accumulation of greenhouse gases, because those gases allow sunlight to enter the Earth but prevent heat form escaping it. Therefore it is very important to know how is and it caused and effected. Consequently what can to do for reduce the “Greenhouse Effect”

In the first place, the global warming is caused by several diseases such as pollution from factories, carbon dioxide from rotting trees, burning of fossil fuels and other causes. Unfortunately, the power plants need this fossil fuels for produce electricity but they contribute to produce global warming even worse, because it produce more greenhouse gases.

In the second place, greenhouse gases are harmful to our environment because they are a mayor source of air pollution. Much of theses gases cause very serious health diseases; for example, respiratory diseases like asthma, allergies, coccidiodomycosis, heart disease, also chronic lung, among others.

You know this is a big problem, but what to do for reduce those effect even the causes? You can help to stop when you recycle. Recycling glass, plastic and aluminum uses les electricity that if these materials were to be made brand new. You need to try use less a car, and walk more often or if it is a long trip, you can take the bus. You could install solar hot water systems, this is possible for you. I know this problem need national policity and government intervention but you can do those things, let is take action now!
