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


reduce
reduce means you should minimize throwing garbages.you should also dispose your garbage properly,you should not let others to throw garbages anywhere,you should separate papers,and plastics.in order to maintain the cleanliness of our environment you should be a good example to many people..recycle,recycle means don't throw your garbage directly,you should check the things that can be needed .reuse.its the same as the recycle.you should not waste the papers that you throw or any materials .

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


To Reuse is to use an item more than once. This includes conventional reuse where the item is used again for the same function, and new-life reuse where it is used for a new function. In contrast, recycling is the breaking down of the used item into raw materials which are used to make new items. By taking useful products and exchanging them, without reprocessing, reuse help save time, money, energy, and resources. In broader economic terms, reuse offers quality products to people and organizations with limited means, while generating jobs and business activity that contribute to the economy.

Historically, financial motivation was one of the main drivers of reuse. In the developing world this driver can lead lead to very high levels of reuse, however rising wages and consequent consumer demand for the convenience of disposable products has made the reuse of low value items such as packaging uneconomic in richer countries, leading to the demise of many reuse programs. Current environmental awareness is gradually changing attitudes and regulations, such as the new packaging regulations, are gradually beginning to reverse the situation.

recylcle

Recycling involves processing used materials (waste) into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production.[1][2] Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.

Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. Although similar in effect, the composting or other reuse of biodegradable waste – such as food or garden waste – is not typically considered recycling.[2] Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing.

In a strict sense, recycling of a material would produce a fresh supply of the same material—for example, used office paper would be converted into new office paper, or used foamed polystyrene into new polystyrene. However, this is often difficult or too expensive (compared with producing the same product from raw materials or other sources), so "recycling" of many products or materials involves their reuse in producing different materials (e.g., paperboard) instead. Another form of recycling is the salvage of certain materials from complex products, either due to their intrinsic value (e.g., lead from car batteries, or gold from computer components), or due to their hazardous nature (e.g., removal and reuse of mercury from various items).

Critics dispute the net economic and environmental benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from confirmation bias. Specifically, critics argue that the costs and energy used in collection and transportation detract from (and outweigh) the costs and energy saved in the production process; also that the jobs produced by the recycling industry can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production; and that materials such as paper pulp can only be recycled a few times before material degradation prevents further recycling. Proponents of recycling dispute each of these claims, and the validity of arguments from both sides has led to enduring controversy.

reduce

Recycle means to process old, used items in order that the material can be used to make new products. Examples of things that are often recycled are glass, plastic, newspapers, aluminum cans, used motor oil, and batteries. Here, reduce refers to lessening the amount of items or resources that are consumed, using only the amount that is needed, and looking for alternatives that will lessen our use. And reuse means extending the 'life' or repurposing an item rather than discarding or throwing it away.
Harder - Recycling is the processes of collecting, processing, remanufacturing, and reusing materials instead of discarding them. This helps conserve raw materials and energy that manufacturers would otherwise use in producing new products. Recycling also reduces the amount of material going into landfills. Recycling helps lessen the pollution that may result from waste disposal. Reducing our consumption of materials and reducing the waste of materials also adds to the conservation of our resources.

Garbage Problem


problems

Garbage litters most of metropolitan Manila as authorities grapple with the unenviable task of finding a dump site for the many tons of rubbish generated by the capital's 12 million residents.

The Philippine government, engulfed in a political crisis over the impeachment trial of President Joseph Estrada, is also working overtime to avoid a full-blown garbage calamity that may test the patience of the metropolis.

The garbage situation reflects the never-ending mess that buffets the two-and-a-half year Estrada administration. Problems include Muslim extremism, kidnappings, rising unemployment and protest actions spawned by accusations Estrada pocketed millions of pesos in kickbacks from illegal gambling operations.

According to government records, metropolitan Manila generates an average 5,854 tons of waste, 29,268 cubic meters, daily.

About 74.14% of the trash comes from households, 9.40% from commercial shops, 7.50% from restaurants, 7.60% from public markets, 0.80% from institutions, 0.41% from street sweepings and 0.14% from river clean up, the records show.

Of the waste, records say only about 4% is recycled, 6% is burned or buried, 25% is illegally dumped or finds its way into the sewers and nearby river systems and 65% is collected by authorized garbage collectors.

''The problem is where to dump these tons of garbage,'' said Visia Aldon, a spokeswoman for the Metro Manila Development Authority (MMDA). ''We have to look for ways.''

Finding dump sites for garbage has proven to be difficult indeed for the government.

The government needs at least 30 hectares a year -- and millions of pesos -- to properly dispose of all waste generated by metropolitan Manila residents, Aldon said.

solution:
This petition is the request big fast food chains in the Philippines to do the following:

1. Use plastic serving plastic plates instead of stryo.

2. Use washable spoons and forks for dine-ins instead of disposable.

3. Use washable plastic glasses instead of disposable.

4. Segregate the garbage from within the store.

5. Adopt garbage minimization programs.

Ways On How To Keep the Environment Clean



Ways on how to keep the environment clean:

The way you should keep your environment clean is to throw your garbages in the right place, do not throw your garbages anywhere......we should dispose it properly and clean.you should fallow on how to dispose your garbage,there are two ways to dispose garbage,there is biodegradable and non-biodegradable.second you should teach others to pick up the garbages that is thrown everywhere and be a good example to everyone.....third, guide them on how to save our environment....just like the picture above....the boy is throwing his garbage in the right place......

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.

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.
