How do you reduce,reuse and recycle at home and school?

REDUCE

Buy a trash can and put all your garbages there to prevent dirty surroundings.But for those things that can be used you can just put or keep them in a cabinet.Reduce the trashes you trow to save money with not buying things anymore.

REUSE

Those things that can still be use are very important.Reusing prevents buying things that are really expensive.Reuse the things that can still be used.Prevent wasting money just because you want your things new.

RECYCLE

Just like reusing, you will not buy new thing if you still have old things that can be use.Recycling papers can help you save money.It is very important because recover waste paper.

Garbage Problem

Garbage Problems (Talking Trash)

In most of the world, including North America, we do one of two things with our ordinary garbage: burn it or bury it. Neither one is good for us or for the environment. Burning garbage in incinerators releases dangerous gases and dust (particulate matter) which contribute to global warming and pollute lakes, forests, oceans and cities half a world away from where they originated. Most incinerators in industrialized countries now remove large quantities of particles and pollutants, thus ensuring cleaner air. But the bulk of what they remove ends up in a landfill.

This site concentrates on landfills, in part because this improvement in incinerator technology has increased the pressure on landfills, and in part because a much higher proportion of garbage in North America is sent to landfills than to incinerators.

Burying garbage also causes both air and water pollution, and simply transporting it to the sites consumes an increasing amount of valuable fossil fuels, which produces more pollution.

As a result, alternatives to the burn-or-bury option are increasingly attractive. Composting heads that list of alternatives.

Ways On How To Keep The Environment Clean

We should pick the plastics,papers and sticks that are scattered on the floor. After picking up the trashes, everyone should know that we shall put it in the proper can,the biodegradable,non-biodegradable trash can. No one should trow garbages anywhere. Instead of burning the plastics we should make "compost pit". Avoid trowing garbages in rivers,lakes,etc. Always keep your surroundings clean.

Ozone Depletion

Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total volume of ozone in Earth's stratosphere (the ozone layer) since the late 1970s, and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions during the same period. The latter phenomenon is commonly referred to as the ozone hole. In addition to this well-known stratospheric ozone depletion, there are also tropospheric ozone depletion events, which occur near the surface in polar regions during spring.

The detailed mechanism by which the polar ozone holes form is different from that for the mid-latitude thinning, but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and bromine.[1] The main source of these halogen atoms in the stratosphere is photodissociation of chlorofluorocarbon (CFC) compounds, commonly called freons, and of bromofluorocarbon compounds known as halons. These compounds are transported into the stratosphere after being emitted at the surface.[2] Both ozone depletion mechanisms strengthened as emissions of CFCs and halons increased.

CFCs and other contributory substances are commonly referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (270–315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol that bans the production of CFCs and halons as well as related ozone depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in skin cancer, cataracts,[3] damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.

The ozone layer protects the Earth from the ultraviolet rays sent down by the sun. If the ozone layer is depleted by human action, the effects on the planet could be catastrophic.

Ozone is present in the stratosphere. The stratosphere reaches 30 miles above the Earth, and at the very top it contains ozone. The suns rays are absorbed by the ozone in the stratosphere and thus do not reach the Earth.
