4. Introduction
• The term sometimes is used to refer specifically to climate change caused by human
activity, as opposed to changes in climate that may have resulted as part of Earth's natural
processes.[In this latter sense, used especially in the context of environmental policy, the
term climate change today is synonymous with anthropogenic global warming. Within
scientific journals, however, global warming refers to surface temperature increases,
while climate change includes global warming and everything else that increasing
greenhouse gas amounts will affect.
• All refuse other than industrial-waste and effluents. It consists largely of easily
decomposable and putrefying organic (animal and vegetable) waste from preparation,
handling, storage, and sale or serving of food.
• Pollution is the introduction of contaminants into a natural environment that causes
instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living
organisms.[1] Pollution can take the form of chemical substances or energy, such as noise,
heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies,
or naturally occurring; when naturally occurring, they are considered contaminants when
they exceed natural levels. Pollution is often classed as point source or nonpoint source
pollution. The Blacksmith Institute issues an annual list of the world's worst polluted
places.
• We can prevent pollution and we can lessen garbage by recycling recyclable materials like
bags, curtains pillows, flower and many more. We should take good care of our
environment. Don’t abuse, especially our garbage. We learn how to recycle in order to earn
an income for helping our family as well to save our Mother Earth .
