To gain an understanding of how global warming might impact humanity, it is necessary to know what global warming is and what its causes are. As narrated in the book “Global Warming and the Future of the Earth”, global warming is the unusually rapid increase in the Earth’s average surface temperature. Yet the impact of global warming is far greater than just increasing temperatures, this heating up adjusts rainfall patterns, amplifies coastal erosion, lengthens the growing season in some regions, melts ice caps and glaciers, and modifies the ranges of some infectious diseases (Watts, 2007). In fact, some of these changes are already occurring in the planet.

Stated in the website A Cooler Climate, the Earth has cycled through many

This is supported by Matthew Robinson in his book “America Debates Global Warming: Crisis or Myth?”. He believed that there exists a connection between temperature rising all over the world and human’s burning of fossil fuels (Robinson, 2008). Burning gasoline, coal, and other fossil fuels have unnaturally heated the atmosphere; these have restructured the atmosphere system and increased the greenhouse gases concentrations (McClure & Stiffler, 2007).

The leading emissions of these greenhouse gases and the most significant human causes of global warming include the build-up of carbon dioxide, and release of methane gas. Methane is acknowledged as the second most important greenhouse gas produced by human activity; as described in the article “Scientists agree: Humans causing global warming”, while the methane-emissions levels are much lower than CO2 emissions, pound for pound methane is a more powerful greenhouse gas; a ton of it has 23 times the warming effect of a ton of CO2. Its chief sources are coal mining and landfill sites, natural gas and petroleum production, and animal agriculture. Animal agriculture is on the rise since meat consumption has increased fivefold in the past years, even if a single cow releases a relatively small amount of methane, the collective effect on the environment of the hundreds of millions of livestock animals
