2. What are the nagative effects? --Landfills problem are people don't like landfill and their not gonna live near by there, because landfill can be smelly. Also, food and garden waste rots down lots, so the gas called methane came out and make landfill pollute. -- Another big problem is the landfills are getting more.

4.What are the 2 ways of dealing with Methan gas? There are 2 ways to dealing with methane gas. one way is flaring and other way is re-use to electricity. But first, bores drilled into the rubbish, and get the methane gas. Then they find enough clean methane gas, and small dirty methane gas. Flaring is use for small dirty methane gas. It is the way that burning these gas. Another way is re-use enough methane gas to electricity. = Global Warming =

__The Four 'R's__
There are four main ways to reduce the amount of rubbish that ends up in landfill sites. They are sometimes called the four 'R's.



__**Refusing**__
Refusing means to say 'NO'. For example, when you go to the shopping mall, you are going to say "I don't want to use plastic bags," or get your cloth bag for use. Also when you buy small thing, you can say, " I can carry them."



__**Reduce**__
Reduce means using less of the things that will end up as rubbish. For example, when you print wrong something, you can use it for your math works, or print again with other side.



__**Re-use**__
Re-use means using something again rather than throwing away. For example, you can wash your plastic bottles clean and use it again for your water bottle, or clean your jam jar after you use, you can put other things.



__**Recycle**__
Recycle means to change a use material to new material. For example when you put your plastic bottle or used paper, jar...etc, the company M.R.F(Material Recovery Facility) will make it new!!!
