Home Rainforest Primer 2. Recent losses in biodiversity 5 Causes of recent declines in biodiversity 5 Causes of recent declines in biodiversity The major causes of biodiversity decline are land use changes, pollution, changes in atmospheric CO2 concentrations, changes in the nitrogen cycle and acid rain, climate alterations, and the introduction of exotic species, all coincident to human population growth. For rainforests, the primary factor is land conversion.
Posted on March 22, by Alexandra Enion According to the Endangered Species International, there are currently close to 17, species in the world threatened with extinction. While this number is staggering, the ecological implications are nothing short of harrowing.
Fish and Wildlife Service estimates that losing just one plant species can have the trickle-down effect of losing as many as 30 other species including Major causes of endangered species essay, insects, and other animal species. The extinction of these endangered species could be disastrous for these ecosystems and for humans as well.
Humans use endangered species for medicinal, agricultural, and commercial needs. In terms of conservation and protecting endangered species, human are generally painted as the culprits. Humans clear the forests, felling trees and destroying the habitats of the animals that live there.
Humans poach these animals for their skins, furs, and tusks and sell them illegally on the black market. Human population growth should surely then spell doom for these endangered species. More humans mean more infrastructure and less habitat for these animals and increased resource depletion of these environments.
However, this does not have to be the case. Humans can just as easily become advocates for change and defenders of the Earth and its species as they can be its destroyers. For change to take effect, we, as members of the same ecosystem, must assume responsibility and promote the survival of these endangered species.
Solving this crisis will not come by only propagating the needs of these animals. The requirements of the people who live amongst these species must also be considered. For instance, one of the major reasons for poaching is poverty.
Laws and regulations criminalizing poaching are beneficial but only to a certain extent. These laws are only helpful in protecting species if they are obeyed and enforced. Thousands of laws both national and international exist protecting these animals and prohibiting international trade selling products from endangered species.
Yet, the black market continues to be inundated with animal products. Although ivory has been protected by the Convention of International Trade in Endangered Species sinceivory trade still thrives especially in Thailand.
The sale of ivory from Thai elephants is legal in Thailand, but ivory from African Elephants is smuggled into Thai shops and passed off as ivory from Thai elephants. Once more enforcing laws against poaching is extremely difficult especially in areas where these elephants live, like the Minkebe national park in Gabon which is roughly the size of Belgium with no roads.
Additionally, corruption amongst officials in the Gabonese government means that arrests do not often stick against those caught poaching the Gabonese elephants.
This increase in poaching has been absolutely devastating to the Gabonese elephant population. Sincethe elephant population in the Minkebe national park in Gabon has decreased by between 44 and 77 percent.
So if laws fall short because of the enormous challenge of implementing them, the solution to solving the endangered species crisis must be more direct and examine the reason for the poaching at the source, poverty. Poverty is a huge motivator in driving individuals who live amongst these endangered species to hunt and kill them for subsidence.
Thankfully, certain organizations have recognized that to save these animals, we must also help the people living among them. One great example of this solution in action is provided by the Snow Leopard Trust. The Snow Leopard Trust participates it was is known as community based conservation.
A key aspect of their strategy is the combination of social and economic drivers to pursue ecological change. Many of the herders in these regions live on less than two dollars a day.
By providing livestock vaccinations and livestock insurance, meaning the trust will pay to buy new livestock if the animal is killed by a snow leopard, the trust works to build up the economic stability of the herders, so they do not have to revert to poaching to make ends meet.
Additionally, through Snow Leopard Enterprises, women villagers can sell their homemade wool garments which can increase their household income by as much as 40 percent each year. The trust also provides educational programs for both children and herders to teach villagers about the importance of conservation.
Teaching villagers how to conserve their resources and coexist successfully amongst the big cats is essential considering the rate of human population growth, 90 percent of which in the coming years will be concentrated in the poorest areas of the world.
The success the Snow Leopard Trust has experienced is two-fold. Another nongovernment organization using the power of the community to protect endangered species, the Wildlife Conservation Society is turning former poachers into defends of the environment.
In Zambia, they have implemented an exchange program where poachers turn in their snares and guns and in return learn alternative professions like farming, beekeeping, or carpentry. Another odd but exciting profession taken up by former poachers in is snail farming.
In the area around the Cross River National Park in Nigeria, local villagers often use the park to and kill the critically endangered Cross River gorillas for bushmeat. As strange as it may sound, the Wildlife Conservation Society has aided these former poachers in establishing these snail farms.
These snails are considered a delicacy in the area and offer an income source other than poaching for the villagers. The snail farms do not only protect the gorillas, but these farms have the potential to be more economically sustainable and prosperous than hunting.There are four major causes ('The Evil Quartet' is the sobriquet used to describe them).
