literature review.

how is Singapore landfill Pulau Semakau helping its surrounding ecosystem in relation with 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 an standard landfill in the United States and how they damage the environment. uses three citations, at least one from a reliable source.
