effect

Pollution: is the introduction of contaminants into an environment that causes instability, disorder,

harm or discomfort to the ecosystem

Landfills: also known as a dump or rubbish dump , is a site for the disposal of waste materials by

burial and is the oldest form of waste treatment.

Greenhouse Effect: is the rise in temperature that the Earth experiences because certain gases in

the atmosphere trap energy from the sun.

So how do I protect the earth from these harmful things?

• The R’s–Reduce– Reuse

–Recycle

Reduce• To reduce your use of natural resources

you help in conservation.

• Examples:

–Use paper versus plastic

–Ride your bike versus riding in an automobile

–Use products with less packaging

–Use products made from recycled products

• To use a natural resource again in the same way or in a different way

• Example:

–Reuse plastic grocery sacks to line small wastebaskets

Recycle• A form of reuse that requires changing

or reprocessing an item or natural resource.

• Materials to Recycle

–Glass

–Metals

–Paper

–Plastics

–Yard and kitchen waste

Recycle Plastics

• Due to several different types of plastics, it is one of the hardest to recycle

• It is important to separate types due to the fact if 1 item from a different type is mixed into a batch, the whole batch is ruined.

• Types are:– Type 1 – soft drink bottles– Type 2 & 4 – plastic bags– Type 6 & 7 –are unable to be recycled

Recycle Metals• You can conserve metals by recycling

food cans and aluminum cans.

• It takes less energy to reproduce cans from recycled aluminum then from raw materials.

• If you recycle cans, then it open more space up in our landfills.

Recycled Glass• Glass can be recycled over and over.

It never needs to be thrown away.

• Recycling one metric top of glass can save one metric ton of mineral resources

• It cuts the energy used to make glass by 25%.

• You can do your part y recycling newspapers, notebook and printer paper, cardboard and junk mail.

• One metric ton of recycled paper saves:

–17 trees

–More than 26,000 liters of water

–Close to 1,900 L of oil

–More than 4,000 kw of electric energy

Compost• A way of turning plant material you

would otherwise throw away into rich garden soil.

• Examples

–Grass clippings

–Leaves

–Fruit and vegtables scraps

–Non meat food scraps
