Biomes and Diversity - Assignment Example This big shift with the invention of farm implements and tools enabled Man to vastly increase his food supplies, stabilize food sources, made food production a secure and predictable undertaking and this incidentally also allowed the arable land to support a much higher population density. Increased food availability made the entire human population grow exponentially. It has also put pressure on the other species of plants and animals, as there is a growing competition for the available food, space, and other requirements for life. Ever since Man burst unto the scene, so to speak, a good number of species had become extinct due mainly to Mans prolific activities. It is a dangerous development, as biodiversity is necessary for ensuring survival of the remaining species. There are strong ancestor-descendant links between various species and their biomes, so the main concerns should be both conservation (wise use) and preservation (leaving untouched). The past century saw the extinction of about 100 species of birds, mammals, and amphibians (Hassan & Scholes, 2005, p. 105) but this background (natural) extinction rate is expected to be 10,000 higher in the next two centuries if based on ancient fossil records, current trends, and computer modeling of extinction rates (M iller & Spoolman, 2011, p. 191). The loss in genetic diversity becomes a serious threat to Mankinds survival as well, because of the links that was mentioned earlier. There are still many undocumented species, in addition to those already well known, which can provide ecological, economic, and medicinal benefits to Man. People can help to slow down the extinction rate by avoiding environmental degradation, reducing their carbon footprint, minimize pollution, mitigate climate change, refrain from introducing invasive or harmful species to a biome, prevent over-exploitation of open common
