Pollution — Preventive Measures

A is false but R is true.

Explanation — We should use renewable energy resources in place of fossil fuels as they help save fossil fuels for future generations and are eco-friendly.

Both A and R are true and R is not the correct explanation of A.

Explanation — Carpooling helps reduce the number of vehicles on the road, which in turn reduces air pollution and fuel consumption.

The advantages of carpooling are:

1. Carpooling reduces each person’s costs, tolls and stress of driving.
2. Carpooling is more environment friendly and sustainable way to travel as sharing journeys reduces carbon emissions, traffic congestion on roads and the need for parking spaces.

Use of public transport rather than private vehicles, offers alternative modes of transport.

It help to reduce air pollution in as public transport including trains, trams and buses, can relieve traffic congestion and reduce air pollution from road transport. The use of public transport must be encouraged if a sustainable transport policy is to be developed.

Smoking zones is designated area in which smoking is permitted. It helps to keep the work place and public place air clean and protects people from effects of passive smoking.

Organic farming is a farming method that involves growing and nurturing crops without the use of synthetic based fertilizers and pesticides. This process involves the use of biological materials, avoiding synthetic substances to maintain soil fertility and ecological balance thereby minimising pollution and wastage.

Organic farming help in saving the soil quality in following ways:

1. Natural balance of soil is maintained. Chemical fertilizers change the balance of soil.
2. Soil texture is improved with use of FYM and compost.

Three characteristic features of organic farming are:

1. Indirect provision of crop nutrients using soil micro-organisms.
2. Nitrogen fixation in soils using legumes.
3. Weed and pest control based on crop rotation, biological diversity, natural predators and organic manures.

Carpooling is more environment friendly and sustainable way to travel as sharing journeys reduces carbon emissions, traffic congestion on roads and the need for parking spaces. Hence, authorities often encourage car pooling especially during period of high pollution or high fuel prices.

Renewable energy resources are environment friendly, do not cause pollution, do not contribute to global warming and are available in infinite supply. Hence their use is of prime importance for our future sustainable living.

1. The main reason behind this plan is to lower the country's dependence on fossil fuels and to reduce harmful emissions from vehicles. Promoting electric buses along major routes like the Golden Quadrilateral is a step toward cleaner and more sustainable transportation.

2. Yes, this initiative can significantly help in reducing environmental pollution. Unlike traditional fuel-powered vehicles, electric buses do not emit smoke or carbon dioxide, which are major contributors to air pollution. By replacing diesel or petrol buses with electric ones, the overall emission of greenhouse gases will decrease, leading to cleaner air and a healthier environment.

The government supports Organic farming as it promotes sustainable cultivation. It is helpful in many ways:

1. Protecting soil quality.
2. Promotes nitrogen fixation in soil.
3. Risk of biomagnifications can be reduced.
4. Indirect provision of crop nutrients using soil micro-organisms.
5. Care for the larger environment and conservation of natural habitats and wildlife.
