PRESERVATION AND

CONSERVATIONOF THE

ENVIRONMENT

DEFINITION OF PRESERVATION AND CONVERSATION OF THE ENVIRONMENT

Conservation of environment simply implies the sustainable use as well as management of natural resources which include wildlife, water, air, and earth deposits. There are renewable and non-renewable natural resources. Conservation of natural resources generally focuses on the needs & interests of human beings, for instance the biological, economic, cultural and recreational values.

Conservationists have the view that development is necessary for a better future, but only when the changes occur in ways that are not wasteful. Read on to know more about preservation and conservation of environment.

THE IMPORTANCE OF PRESERVATION AND CONSERVATION OF THE ENVIRONMENT

As far as preservation of environment is concerned, it tries to maintain the present condition areas of the nature or Earth which are not yet touched by humans. This is because of the fat that mankind is encroaching onto the environment at such a rate that various wild landscapes are being given over to farming, industry, housing, tourism and other human developments.

And we lose much of the natural areas. Preservationists also strongly support the protection of nature for purely human-centered reasons. However, some adopts less human-centered approach to environmental protection, placing a value on nature that does not relate to the needs and interests of human beings. But is a fact that by preserving and conserving environment we can make a healthy atmosphere to live in.

THE PRACTICE OF reUSING MATERIALS

Materials can be reused in many areas of a retail operation, starting with the construction of the store. The Greening Retail database contains two case studies of retailers who have incorporated reused materials in building and in fitting out their stores.

Like waste reduction, reusing materials and products can happen at all points in a supply chain. Of the 27 examples of materials reuse in the database, there is one that deals with reusing packaging for transporting goods to the store.

Five of the cases are about reducing packaging at the store level, while 14 are in regards to packaging for customers. This large number is due to the movement to reduce the number of single-use bags used for purchases.

A store may provide services that will extend the life of a product by implementing a product return policy. Five case studies in the database tell about retailers who do this.

The following table summarizes the types of practices found in the Greening Retail best practice database that pertain to the reuse of items and includes the number of companies for which this practice is described in the database.

THE PRACTICE OF RECYCLING MATERIAL

Recycling is a process to change 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 plastic production.[1][2] Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.

There are some ISO standards related to recycling such as ISO 15270:2008 for plastics waste and ISO 14001:2004 for environmental management control of recycling practice.

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.
