Let’s break it down. Global warming is the current rise in the average temperature of Earth's oceans and atmosphere and its projected continuation. The scientific consensus is that global warming is occurring and was initiated by human activities, especially those that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning of fossil fuels. This finding is recognized by the national science academies of all the major industrialized countries and is not rejected by any scientific body of national or international standing.
Global warming has a variety of causes. One of the largest factors contributing to global warming is the general problem of overpopulation and its many effects. We consume more items which take more energy to make, drive more cars, and create larger amounts of garbage. These factors all increase the global warming problem. Using a refrigerator releases dangerous gases, turning on the lights requires energy from a power plant, and driving to work causes gas emissions from the car and countless other normal activities. The most common gas is carbon dioxide, accounting for about 50% of all greenhouse gases. Other gases, including methane, CFCs, nitrogen oxides, and ozone, also contribute to forming the greenhouse layer. Our landfills are nearing capacity and with that they are being filled up with products that leak toxic additives into our groundwater. Take plastic water bottles, for example. The numbers are staggering. In 2003, there were some 40 million bottles a day that went into the trash; not to mention the toxicity we get during consumption and the fact that it takes some 1,000 years to biodegrade, if ever.
