According to Discovery.com, the worst effect global warming is likely to have is the destruction of the ecosystem. Threats to supplies of fresh water and clean air, as well as to energy, food and medicine are likely to threaten not just human lifestyles but survival itself. Additional serious and negative effects caused by global warming are the concomitant loss of biodiversity, with 30 percent of the species alive today at risk should average temperatures continue to rise, causing the loss of habitats needed for those species to survive.

Discovery.com points out that scientists have concluded that if global warming continues, no part of the world will be free of its effects. Effects of global warming such as the bleaching and death of coral reefs are already being noticed. If these effects continue to occur, humans may be forced to fight for diminishing resources.

  • Q:

    What are the advantages and disadvantages of selective cutting?

    A:

    Selective cutting allows ecosystems to support more wildlife than clear cutting and allows forests to retain some of their resistance to disease and pests. In addition, studies show that carbon uptake levels will quickly recuperate if selective cutting is done properly. Some of the disadvantages are that some species may not regenerate quickly, and thinning the forest may lead to increased damage from ice, storms or fires.

  • Q:

    What are the main causes of global warming?

    A:

    Global warming results primarily from human activities that cause an increase in the amount of greenhouse gases in the atmosphere, which in turn compromise the atmosphere's functional capacities, including regulating temperature and weather patterns, as stated by NASA. Global warming takes place over long periods of times, and it results from an abnormally high buildup of chemicals in the atmosphere. These gases include natural elements like carbon dioxide and oxygen, as well as synthetic compounds like volatile organic compounds, or VOCs, and chlorofluorocarbons, or CFCs.
