Paragraph on "The greenhouse effect"

The earth is getting warmer. This is because of the greenhouse effect. The sun's rays penetrate the atmosphere, which absorbs some of its heat and reflects the rest back into space. However, now the thick gases produced by human activities trap too much heat and, consequently, the temperature of the earth's atmosphere has been steadily increasing. This increase in temperature will affect all life on the planet.

The two main gases responsible for the greenhouse effect are carbon dioxide and methane. Many governments have begun to look at ways of reducing the emissions of greenhouse gases. Some of the steps taken are large-scale planting of trees, introducing taxes to be imposed on industries producing the harmful gases, and promoting alternative sources of energy, the generation of which will not produce the harmful gases.
