**Landfill**

A landfill, also known as a dump or rubbish dump, is a huge hole where large amount of waste meterials are buried under the earth.

**Mathane Gas**

Methane gas is a chemical compound with the chemical formula CH4. It is greenhouse gas and it is explosive. It is the simplest alkane, and the principal component of natural gas.It is produced in large quantities from decaying organic wastes within municipal solid waste, and all organic material filled landfills.

What are the 2 ways of dealing with Methane gas?  How is Methane dangerous?
 * flaring Methane gas (burn Methane gas)
 * re-use to electricity

Methane gas kills when the body absorbs the methane into the blood stream when inhaled during normal breathing. It displaces the oxygen and the body becomes disoriented and unable to make rational decisions. It makes the person lethargic and they want to go to sleep and eventually die of oxygen deprivation. Methane is an odorless and colorless gas which makes it more harmful.

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.

R educe : make it smaller in size or amount, or less in degree. For and example by __reducing__ the amount of rubbish, you can change many things.  R e-use :  to use item more than once For an example you __reuse__ plastic bottle instead of buying new one for your drink. R <span style="font-family: 'Lucida Console',Monaco,monospace; font-size: 120%;">ecycle : processing use meterials into new products to prevent waste of potentially useful meterials For an example if you __recycle__, you can reduce the amount of waste going to landfill. <span style="font-family: 'Lucida Console',Monaco,monospace; font-size: 168%;">R <span style="font-family: 'Lucida Console',Monaco,monospace; font-size: 120%;">efusing : deliberately do not do it, or say to say "No". For an example you __refuse__ to use plastic bags when you go shopping.

If you put plastic bags anywhere, little kids or other animals can eat it and it can cause the trouble with it. Birds get trapped without hope to free themselves. Nearly 200 different marine life species,including whales, dolphins, seals and turtles die because of the plastic bags. They die after ingesting bags which they accidentally identify as food. <span style="-webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; border-collapse: collapse; font-family: arial,sans-serif; line-height: normal; white-space: nowrap;">

 * If you use a fabric stock market reusable shopping bag, you can save 6 plastic bags per week. It means you can save 288 plastic bags per year.


 * <span style="font-family: Arial,Helvetica,sans-serif;">You can reuse plastic bags in creative ways. For example, <span style="-webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; border-collapse: separate; font-family: Arial,Helvetica,sans-serif; font-size: 13px; white-space: normal;">plastic bags can be used to stuff a giant pet pillow, to line paint trays or the baseboards when painting a room, or they can be stored in the car for wet clothes and shoes.


 * Fill a bag until it's ready to burst. Place as many items as possible in one plastic bag and you'll find it easy to reduce waste.
