This document discusses various topics related to environment protection. It defines environment protection and discusses key issues like the greenhouse effect, acid rain, wildlife extinction, deforestation, pollution, and ecology. It specifically examines selective collection and recycling, noting that selective collection is one stage of recycling that separates waste to transform it into useful products. Recycling reduces energy consumption and excessive use of natural resources. The document also defines environmental pollution as an undesirable change in the physical, chemical, and biological characteristics of air, land, and water. Pollutants are categorized as either biodegradable or non-biodegradable. Biodegradable pollutants are broken down by microorganisms while non-biodegradable poll

8. Selective collection and recycling
 Selective collection - is one of the recycling stages, together with the
separation and with the processing of some waste compounds, in order
to transform them into useful products.
 Recycling - is the process that reuses old products and materials in order to
produce and create new ones, without resorting to new raw materials.
 Thus reducing both the energy consumption necessary to extract the raw
materials and to destroy the waste, and also the excessive use of natural
resources.

10.  Environmental pollution is defined as the undesirable change in physical,
chemical and biological characteristics of our air, land and water.
 Pollutants are generally grouped under two classes:
(a) Biodegradable pollutants - Biodegradable pollutants are broken down by the
activity of micro-organisms and enter into the biogeochemical cycles. Examples
of such pollutants are domestic waste products, urine and faucal matter,
sewage, agricultural residue, paper, wood and cloth etc.
(b) Non- Biodegradable pollutants - Non-biodegradable pollutants are stronger
chemical bondage, do not break down into simpler and harmless products. These
include various insecticides and other pesticides, mercury, lead, arsenic, aluminum,
plastics, radioactive waste etc.
