Hybrid based engines are now promoted by many as a great way to prevent global warming. In fact we often see many celebrities that prefer the Toyota Prius, a popular hybrid car over most American brand of vehicles. Hybrid cars help by providing better gas mileage and reducing the harmful emissions that lead to global warming because the car can run off both gasoline and electric power. Some rental car companies also offer hybrid vehicles to their customers as an alternative choice.

Other technologies for future automobiles include fuel cell based vehicles. Fuel cells change hydrogen and oxygen compounds into electricity witch it uses to run the vehicle. This technology is already used by some organizations, and although it is not yet as popular as Hybrid based vehicles, it will also help ease global warming in the future. Alternate fuels are another method being explored such as Ethanol, alcohol, and bio-diesel. These alternate fuels can be made from a wide variety of sources including vegetable oils such as soybean and corn oils and even animal by products.

Most have us are aware that there are other alternatives and ways to help reduce factors that cause Global Warming but we all have to do our part to enact including the transportation industry.

Greenhouse gases are released both by nature and human activities. In the wild, methane, a greenhouse gas, is released from arctic tundra and wetlands. The Earth is also bound to undergo a cycle of climate change, that usually lasts about 40,000 years.

However, man-made causes are the most numerous and the most damaging. Pollution, mainly caused by the burning of fossil fuels, is the main factor that disrupts the Earth’s climate. When these fuels are used, or coal and oil are mined, CO2 is released into the atmosphere.

Fossil fuels are used at a greater scale since there are more and more people driving a car, using transportation and more agriculture. Another source of methane is manure, produce by more animals raised for food. Trees are being cut down to make room for homes and buildings, that would convert our CO2 to oxygen. Buildings structure alone account for about 12% of CO2 emissions.

Deforestation is the second cause of atmospheric carbon dioxide. 34 million acres are being cut down each year, leading to 25% of all carbon emissions entering the atmosphere. The forests that we are losing every year can account for an absorption rate of 2 billion tons of carbon annually.
