The world population is increasing at a massive rate and with the increase in population growth more space is needed for building houses, roads, schools, hospitals, etc.
“The world's population will rise from 6.5 billion to 9.1 billion by 2050, according to a United Nations survey released Thursday. Much of the growth will take place in the least-developed countries, where a high rate of mortality is outweighed by an even higher rate of fertility. Their current collective population of 800 million is projected to swell to 1.7 billion in 2050.” (Wald)
Human population growth can be seen as having a major impact on the environment as human activities are increasing, pollution is increasing and habitats of various living organisms are being destroyed. The worlds natural resources are being used at a much faster rate and it won’t be long before they are diminished. There is growing concerns from various groups and organizations on the impact to the environment and the living organisms and the amount pollutants produced by human activities.
Global warming is one of the current environmental problems facing us today. Global warming is increase in the earth’s average temperature caused by greenhouse gases. Greenhouse gases include carbon dioxide, carbon monoxide, methane, nitrous oxide, and fluorocarbons. The greenhouse gasses trap the sun’s light within the earth’s atmosphere and causes an increase in the earth’s average temperature. Global warming causes the melting of glaciers and polar ice bergs leading to an increase in sea levels, severe floods and droughts
Another current environmental problem is the depletion of the ozone layer. Ozone layer in the earth’s atmosphere has a high concen...

- Hybrid Cars There are two configurations for hybrid cars. The first configuration uses gasoline engine to run a generator. The generator supplies electricity to the motor, which drives the wheels, which allows the gasoline engine to run constantly while achieving optimum fuel efficiency. This thereby minimizes emissions owing to incomplete combustion. A hybrid car with parallel configurations uses both an engine and a motor to drive the wheels depending on driving conditions. "A hybrid car is an automotive equipped with two or more sources of motive energy" (http://www.howstuffworks.com/hybrid-car1.htm).... [tags: essays research papers]
