Non-renewable are the sources that cannot be renewed and available in limited quantities. Examples include coal, oil, and natural gas. As petrol, diesel and coal are non-renewable material we have to use them carefully. Apart from this, use of such resources increase air pollution by emitting smoke.

Hence it is always best to reduce the usage of coal, petrol and diesel. This is achieved by car-pooling or using public transport and by using bicycles to travel short distances.

Reduce in its original sense means to limit the usage.

But in environmental sense reduce also has another meaning.

It means in the process of producing any product, the raw material used should be in such a way that it produces less waste.

Organic farming is a technique of developing agriculture by using organic fertilizers like manure, compost, green manure, bone meal etc. Use of synthetic fertilizers are completely eliminated to develop healthy agriculture.

Sikkim has declared adoption of organic farming in the year 2003. It is the only state to convert entire agriculture into organic farming.

Reuse: it is using of a product multiple times. The product is used directly without any treatment. Any item in good condition can be reused.

By reusing we can reduce municipal wastage and reduce environmental strain.

The correct hierarchy of the process is reduce, reuse and recycle.

Reduce: means in the process of producing any product, the raw material used should be in such a way that it produces less waste.

Reuse: it is a using of a product multiple times. For example milk bottles in which milk is served can be used daily to serve milk.

Recycle: it is complete conversion of a product into the state of raw material.

Many of the environmental problems are caused due to the harmful effects of fossil fuels. Climate change, air pollution, oil spills, and acid rain etc. result from our dependence on fossil fuels. Apart from this extensive use of fossil fuels result in their depletion. Hence there is an immediate need to search for the alternative fuels.

Example solar energy can be utilised to produce electricity instead of coal because solar energy is abundant source of energy.

It is always necessary to reduce the waste to keep environment safe from pollution

It can be achieved by many ways. Some of them according to the options given are

Switching to reusable products like milk bottles instead of packets so that the bottles can be used multiple times, reducing municipal waste.

Buying items with less packaging as it obvious that more packaging produces more wastage.

Buying bulk products is another important solution to reduce waste because individual packing requires more packaging when compared to bulk packaging.

Biogas which is also called as Gobar gas is obtained from organic waste. Biogas is a gaseous fuel which is a mixture of different gases that are formed by break down of organic matter in the absence of oxygen. Raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste are used for the production of biogas.

• Reuse: It is using a product multiple times. The product is used directly without any treatment. Any item in good condition can be reused.
  
• By reusing we can reduce municipal wastage and so reducing environmental strain.
  

Recycling is a process by which wastes are converted into reusable products, thereby reducing the usage of raw material and energy and controlling air water and soil pollution.

Among the given options paper is recyclable material.
