Question

how is conservation of resources possible? discuss it

​

Answer 1

Answer:

• Buy less stuff (use items as long as you can, and ask yourself if you really need something new).
• Reduce excess packaging (drink tap water instead of water from plastic bottles).
• Recycle materials such as metal cans, old cell phones, and plastic bottles.

Answer 2

Answer:

Method # 1. Material Substitution:

There are many possibilities of material substitution by which, the use of a material resource can be restricted by finding an alternative resource. The problem in this is that many materials have extensive uses and also joint uses.

Copper sheet can be substituted by aluminium, which at the same time would reduce demand for soldering agents made from and lead. Aluminium is being extensively substituted for tin, particularly, in the production of metal cans and containers. Plastics are being used for insulation and anti-corrosive purposes where lead and zinc respectively were previously used.

ADVERTISEMENTS:

But, the essential points in the discussion of material substitution are as follows:

(a) We cannot expect a neat “phasing” of scarcity, such that, as one resource runs out, another becomes available and so on. There is possibility of complete sets of raw materials, substitutable among themselves will be depleted at about the same time.

(b) The substitution may take place with a time lag sufficient to cause disruption in the productive activities of the economy.

(c) Further, the substitute material may cause more pollution than the materials which were in use. For example, aluminium smelters may involve more pollution than their counterpart for tin.

ADVERTISEMENTS:

(d) The substitute materials may well require higher energy inputs, as is the case with low-grade copper exploitation.

Method # 2. Product Life Extension:

This is a method by which the durability of the product is extended by deliberate design, so that the need for replacement would be postponed.

It is a common practice that many modern producers design the goods for early disposal by the consumers to serve twin purpose of:

(a) Boosting the sales and profits of the producing firm by encouraging consumers to go in for replacement of their goods more rapidly,

ADVERTISEMENTS:

(b) Reflecting consumer’s apparent desire for rapid changes of their goods for the sake of novelty.

By extending the life of the product, the requirement of resource materials can be appreciably brought down.However, the product life extension method has some disadvantages. It requires the customers to hold on the goods for a longer period.

This will be possible only with substantial increase in the quality of the product to extend its durability. Otherwise, the product may become less suitable and the objective will be defeated. Thus, the product life extension has a potential role to play in conservation of resources.

Method # 3. Recycling:

Recycling is a popular and widely practiced method throughout the world by many industrial units. This is a process by which the life of resource is extended by means of recycling it or reusing it as an input or output. This is applicable only to on-energy resources, since the use of a material as an energy resource results in its useless dissipation into the atmosphere.

Industrial wastes and by ­products can be profitably recycled. But, the profit seeking firm will make an attempt to recycle a product only when the cost of recycling is lower than use of “virgin” resource material. Further, the differential cost between recycling and using virgin resource must remain for a fairly long period.

The recycling decisions depend on so many factors such as:

(i) The value of the resource after recycling,

(ii) Reduction in pollution due to the reduction in residuals disposed of directly to the environment, and

(iii) Reduced demand for land for disposal purposes, releasing it for alternative social uses.
