Introduction: The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times‚ a report released by the United Nations World Meteorological Organization (WMO) warns recently. Even if we managed to halt our greenhouse gas emissions today‚ and this is far from the case‚ they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate. The latest

Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150

What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

1)What are all of the greenhouse gases? There are four greenhouse gases that trap and absorb heat on Earth so living organisms can sustain life. Not only are they the greenhouse gases up also make up the 1% in the atmosphere. The greenhouse gases include water vapor (H2O)‚ carbon dioxide (CO2)‚ methane (CH4)‚ and nitrous oxide (N2O). H20 - this is one but it not really talked about on the website 2) Which one is completely human related? (meaning it is not found naturally in the environment)

Is genetic engineering the answer to ending global hunger? SCI 207 March 23‚ 2013 Hunger is one of the root causes to poverty due to the exponential growth of the human population. The effects of hunger are diverse and have a negative effect on the growth and life span of a person. Scientists believe that they can help alleviate hunger problems through alteration and modification of genes in foods. The research in this paper will give the pros and cons of GM foods and help answer the following

Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? I personally believe that we are already preserving when it comes to wondering if we are going to become extincted. We as human have a hard time not reproducing‚ this meaning most humans that become married usually begin having children within the first 5 years of their marriage if they haven’t married and already have children. This being said we may not leave an
