Garbage popllution

Garbage pollution has been a major problem of man since the creation of synthetic materials. Apprehensively, man has been trying to reduce this problem. But paradoxically, anthropogenic activities are the major factors that brought it into place.

Waste (also known as rubbish, trash, refuse, garbage, junk) is unwanted or useless materials. Litter is waste which has been disposed of improperly.

Anything man throws ends up on the biggest landfill, the middle of the ocean. But before it reaches the ocean it traverses to the large expanse of saline water, the sea. And the sea house different organisms which make it the most diverse place on earth. Messing with it is like messing with the whole world that could turn out in imbalance.

Waste is directly linked to human development, both technologically and socially. The compositions of different wastes have varied over time and location, with industrial development and innovation being directly linked to waste materials. Examples of this include plastics and nuclear technology. Some components of waste have economical value and can be recycled once correctly recovered.

Waste is sometimes a subjective concept, because items that some people discard may have value to others. It is widely recognized that waste materials are a valuable resource, whilst there is debate as to how this value is best realized. Such concepts are colloquially expressed in western culture by idioms like "One man's trash is another man's treasure."

Landfill-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.
