Pulau Semakau

How is Singapore landfill Pulau Semakau helping its surrounding ecosystem in relation to standard landfills in the United States?  I need two pages of a literature review about the topic decried above.  you will need to describe how is Semakau not a danger to the ecosystem and instead is beneficial, and compare it to a standard landfill in the United States and how they damage the environment. uses three citations, at least one from a reliable source.  For more information on Pulau Semakau read this: https://en.wikipedia.org/wiki/Pulau_Semakau
