Implications: Economic: Unfortunately, wildlife corridors like the TTC can be expensive to create and maintain. Daniel Simberloff, a renowned ecologist and biologist with a Harvard degree, says that “maintaining a corridor would be much more expensive than creating refuges for endangered species,” suggesting that moving larger animals from one plot of land to another would be more cheaper than buying land and building a corridor. . This expense could dissuade people from supporting this method even if the results show that it is a good habitat for breeding, which will have a negative impact on Sumatran tiger populations. Environmental: Another disadvantage is that the corridor could be at risk due to deforestation itself which could subsequently increase the amount of deforestation of the land. Little can be done to prevent the corridor from being cut through, putting Sumatran tigers or any other species that use the corridor as a breeding ground or habitat at risk. Impact on humans and other organisms Similar to solution 1, the corridor can help maintain and increase the Sumatran tiger population with the concern that this will result in a decrease in the population of prey species because more tigers eat more prey. However, the corridor provides habitat for these prey species allowing them to reproduce and increase in numbers in a similar manner, while increasing biodiversity that outweighs the disadvantage. Alternatively, this could pose a risk to local people and plantations, for example by occupying land that could produce money for the local economy. To combat this problem, corridors should be effectively planned as far away from local villages as possible to reduce any conflict, but plantations should also be consulted before the corridor is built to find an area of ​​land that satisfies… half of the card. .....iable because it's old. However, this source discusses the history of the Sumatran tiger and the history of their genetics, such as how an event that occurred thousands of years ago isolated Sumatran tigers from the mainland tiger leading to a very small, closely related group. Since these are not results that examine trends and patterns but that discover facts, I can suggest that they are reliable even if they are old. I also consider the results valid because the magazine is edited by 4 people qualified in scientific fields (natural history, health and chemistry). I also believe this source is valid because it says the source was "Accepted 15 January 2010" - this suggests an element of peer review or checking and with the accepted source it is safe to assume the source is valid.10- Zoological Society London .
