Positive and Negative things about recycling:
Positives: a. Increase the supply of raw materials and reduce the demand for "virgin" materials. (keep the cost of raw materials down) b. Reduce the demand for landfill space. (keep the cost of trash disposal down) c. Reduce the environmental effects of extracting new raw materials from the earth.

Negatives: a. Requires energy to collect and re-process materials back into raw form. (re-use is a better option) b. Results in potentially less pure raw materials (small amounts of foreign materials mixed in with plastics). c. Results in lower quality materials (plastics degrade more every time they are re-processed...not the case with metals). = Research Questions: =

1.What is landfill?
A **landfill**, also known as a **dump** or **rubbish dump** (and historically as a **[|midden]**), is a site for the disposal of [|waste] materials by burial and is the oldest form of [|waste treatment]. Historically, landfills have been the most common methods of organized [|waste disposal] and remain so in many places around the world.

The negative things about landfill:

 * They produce methane gas which is very explosive and can make a hole in O-Zone layer.
 * They kills animal because the animals(mostly birds)think they are food and swallow things such as plastic ring in coke bottle.
 * They are smelly and can cause diseases.

3. what is methane gas?
Methane gas is made when rubbish begins to rot. Methane gas can be useful and dangerous by being a fuel to make electricity and making holes in O-Zone layer. Methane (CH4) is a greenhouse gas that remains in the atmosphere for approximately 9-15 years. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period and is emitted from a variety of natural and human-influenced sources. Human-influenced sources include landfills, natural gas and petroleum systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial process.

4. two ways to stop methane gas.

 * 1) Burn it in the incinerator.
 * 2) Turn it in to electricity if the gas has good quality and quantity.

= 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 saying No to new tings such as plastic bag and use the one you got from last time. example:Refuse to new plastic bag and use previous one.

Reduce
Reduce means to minimize something such as recycling-paper,cardboard and compost food scrap. example: You can reduce food scrap by recycling them.

Re-Use
Re-use means to use something that isn`t new again. example: I will reuse ice cream container as air tight container.

Recycle
Recycle means to make new thing from old and used tings such as air tight container. example: You can recycle paper,can and pizza container if there isn`t any food in it.
