The green house effect is happening right now at this very moment! According to our text book in physical geography; human induced burning fossil fuels such as natural gas, coal, oil and gasoline raises the level of carbon dioxide in the atmosphere, and carbon dioxide is a major contributor to the green house effect and global warming. (McKnight’s, Physical Geography, P.75, 2011)What will happen to the Earth and its people, animals, plants, lands and oceans if we fail to successfully address the environmental issues we face today? Our global population, air quality, human health, our food supply drinking water, wild life and habitats will all be effected with global warming. What can you do to preserve and protect the environment? There are many things we can do to help our mother earth. Opposition may be the large oil, auto, and coal companies and any explanation they may give from their studies will be bias.
WHAT IS GLOBAL WARMING?
Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent.

What causes the greenhouse effect one might ask? According to the movie “An Inconvenient Truth”, Life on earth depends on energy from the sun. About 30 percent of the sunlight that beams toward Earth is deflected by the outer atmosphere and scattered back into space. The rest reaches the planet's surface and is reflected upward again as a type of slow-moving energy called infrared radiation.(movie; An Inconvenient Truth,2006) The heat caused by infrared radiation is absorbed by "greenhouse gases" such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere. Although greenhouse gases make up only about 1 percent of the Earth's atmosphere, they regulate our climate by trapping heat and holding it in a kind of warm-air blanket that surrounds the planet. This phenomenon is what scientists call the "greenhouse effect." Without it, scientists estimate that the average temperature on Earth would be colder by approximately 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain our current ecosystem.
How do humans contribute to the greenhouse effect? In our textbook “While the greenhouse effect is an essential environmental prerequisite for life on Earth, there really can be too much of a good thing. The problems begin when human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature. * Burning natural gas, coal and oil -including gasoline for automobile engines-raises the level of carbon dioxide in the atmosphere. * Some farming practices and land-use changes increase the levels of methane and nitrous oxide. * Many factories produce long-lasting industrial gases that do not occur naturally, yet contribute significantly to the enhanced greenhouse effect and "global warming" that is currently under way. * Deforestation also contributes to global warming. Trees use carbon dioxide and give off oxygen in its place, which helps to create the optimal balance of gases in the atmosphere. As more forests are logged for timber or cut down to make way for farming, however, there are fewer trees to perform this critical function. * Population growth is another factor in global warming, because as more people use fossil fuels for heat, transportation and manufacturing the level of greenhouse gases continues to increase. As more farming occurs to feed millions of new people, more greenhouse gases enter the atmosphere. (American Geophysical Union, Human Impacts on Climate, adopted by AGU Council, December 2003.)
