Enhancement of Human Assisted Migration - Essay Example

Enhancement of human-assisted migration gives the best solution for preventing the extinction of surviving species in our ecosystem. If the climate change report predictions of 2 to 6 degrees Celsius of warming rate for the twenty century were true, then there would be minimal time for the stranded species to shift to better habitats unless there is human intervention. Many consider it scary and risky to carry and bring these outside species into the communities where they can flourish. While others consider it to be a much more risk when the species do not adapt to the new habitats they are taken and also claim the impossibility of moving all the species together to their new ecosystem.

If the species were to be left to try and adapt to the harsh climates it would lead to more of the species getting to extinction which is riskier than taking them to better places. Précis 2Townsend Peterson lead a team at the University of Kansas which created a model which predicts that species turnover due to local die-offs and new arrivals will exceed 40 per cent in many places due to the harsh climate change. The team took a population of 1870 species of insects, birds, and mammals across Mexico and based their arguments on the projections of the climate changes in the year 2055.

This team published their model in Nature in order to give people a clear view of the predictions that have already begun in several areas and take the precautions so as to protect the existing species from die-offs, for instance, the die-offs that have withered juniper-pinon woodlands across the American Southwest. The region suffered from drought in the 1950s and again starting several years ago (Douglas,6). Future predictions can be made by the use of models and since the climate models predict increasingly frequent drought in the Southwest, the species there will either die off or migrate.

Harsh climatic conditions lead to some species die-offs and immigration of species and this leads to increased competition in the new habitat with the members of the habitat causing conflicts that result in the die-offs as advocated by Peterson’s team. Some people claim that the die-offs of the species may open doors to new arrivals and add up more nutrients to the soil making it a better habitat for other species. Also, some argue that the existence of a species takes place as a natural process and humankind should not intervene. In order to be certain of the future ecosystems, ecologists should take precautions need to be taken by the ecologists to protect the current species.
