Global Warming is the increase in the average temperature of the atmosphere, oceans, and landmasses of Earth. The reasons for the increase in atmospheric temperature are the burning of fossil fuels such as coal, oil and natural gas which release carbon dioxide and other substances known as “greenhouse gases” into the atmosphere. This release saturates the atmosphere with these gases which act as insulators and retain more of the heat provided by the Sun. The average surface temperature of the Earth is about 15 °C and in the last hundred years, the temperature has risen by about .6 °C.   Because of the rise in the earth’s temperature, polar ice caps and glaciers are melting and causing warmer ocean temperatures.  This is expanding the oceans volume and will ultimately raise the sea level by 9 – 100 cm.  Once the sea levels are affected, the earth will be subject to flooding on many islands, especially along coastal regions. This will cause areas in warmer climates to receive more rainfall and soils will dry out faster between storms. The effects from the flooding and dried out soils will be damaged food crops and disruptions in the food supplies in some parts of the world.  As a matter of fact, plants and animals species will relocate towards the north and to higher elevations to seek cooler temperatures. Some species, like polar bears, face extinction because of this shift.  Your help is needed to stop global warming.  Below is a list of factors that affect our environment which have the potential to worsen Global Warming:

1.  Cigarettes –  Trees are being cut down at an alarming rate to make and produce cigarettes, which when smoked release greenhouse gases. On top of that, it takes 5 years for a cigarette butt to biodegrade (and they release harmful toxins and chemicals into the environment during this time).

2.  Aerosols – Hairspray and other aerosol products end up in our atmosphere and cause the ozone to further deteriorate.

3.  Industrial factories – Factories are one of the main reasons why there is so much pollution in our air. They emit gases like Nitrogen oxides and Sulfur Dioxide, both of which cause acid rain when mixed with water in the air.

4.  Pesticides/Insecticides/Fertilizers – The runoff from these toxic chemicals enters streams, ponds, and our drinking water. Pesticides don’t just kill bad insects; they also kill beneficial insects and wildlife, and create many health problems for humans.

5.  Lawn mowers – Small gasoline engines in mowers, chain saws and leaf blowers emit high levels of pollutants that cause smog. The Environmental Protection Agency (EPA) estimates that gasoline-powered landscape equipment is responsible for more than 5 percent of urban air pollution.

6.  Air Conditioning – Air conditioning uses up energy, some of which is supplied by oil and coal-fired generators which emit pollutants that contribute to smog. The chemical Freon that is used in air conditioners and refrigerators contains chloro-fluoro-carbons (CFC’s), which are suspected of causing damage to the ozone layer.

7.  Electricity – Electrical needs contribute to people’s fossil fuel dependence. Energy-hungry filament bulbs should be replaced by compact fluorescents. Generating electricity contributes to smog.

8.  Cars – The car is bad for the environment because of the many gases it emits that pollute the air. They emit carbon monoxide and nitrogen oxides, gases which make acid rain, and hydrocarbons, one of the causes of modern day smog.
