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

REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers.
REUSE is do use an item more than once.
RECYCLE is to use again an item that is recyclable like plastic bottles etc.
I reuse, reduce and recycle garbages in the house and school, we must throw them properly and keep the recyclable ones because we can still use them.

Garbage Problem

I will throw my garbage in the proper disposal and separate them from NON-BIODEGRADABLE and
BIODEGRADABLE.We must do it at home or even in the school.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.
Burning 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

I will pick-up the garbage anywhere even in our houses we need to pick them up and put it in the trash can. We need to segregate our garbages into NON-BIODEGRADABLE and BIODEGRADABLE. We need to recycle the plastic bottles because we can still use them if we recycle them.
People should not throw garbage everywhere but instead they will put it in the trash can.

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.

Ozone is a bluish gas that is formed by three atoms of oxygen. The form of oxygen that humans breathe in consists of two oxygen atoms, O2. When found on the surface of the planet, ozone is considered a dangerous pollutant and is one substance responsible for producing the greenhouse effect.

The highest regions of the stratosphere contain about 90% of all ozone.

In recent years, the ozone layer has been the subject of much discussion. And rightly so, because the ozone layer protects both plant and animal life on the planet.

The fact that the ozone layer was being depleted was discovered in the mid-1980s. The main cause of this is the release of CFCs, chlorofluorocarbons.

Antarctica was an early victim of ozone destruction. A massive hole in the ozone layer right above Antarctica now threatens not only that continent, but many others that could be the victims of Antarctica's melting icecaps. In the future, the ozone problem will have to be solved so that the protective layer can be conserved.
