• Stream Bank Protection: During the rainy season or floods, the vegetative cover of the stream bank is washed
away into the stream, which leads to soil erosion. This can be prevented by forming vegetation, constructing
rock ripraps, planting trees and growing native grasses and shrubs along a stream bank.
Energy Conservation
Energy conservation is the conservation of non-renewable resources like coal, oil and natural gas by using it
judiciously and reducing its wastage, so that it can be preserved for the generations to come. Increase in the
consumption of oil and natural gas has lead to an increase in the level of carbon dioxide causing change in climatic
conditions. There are different ways to conserve energy:
• Using alternate sources of energy: There are many alternate sources of energy that can be utilised for different
purposes:
¬ Wind Energy
¬ Geothermal Energy
¬ Solar Energy
¬ Nuclear Energy
¬ Tidal Energy
¬ Biofuels and Biomass Energy
• Using energy efficiently: This is an important factor for environmental protection, financial benefits for
individuals and for the country as a whole. Following the method given below will be a great help in the
consumption of energy efficiently:
¬ Using maximum daylight, CFLs, turning off electrical appliances when not in use.
¬ Using energy efficient appliances at home and in offices. It consumes less energy and saves more money.
¬ Using public transport, carpooling, driving less and walking more or using a bicycle for small distances.
¬ Keeping the doors closed for efficient use of air conditioners.
• Creating awareness among people: If we create awareness among our people, then half of the battle in
conserving energy is won. This awareness can be brought by:
¬ Educating people for efficient use of energy at homes and in offices.
¬ Supporting campaigns and government initiatives for consumption of alternate sources of energy.
¬ Going for Reduce, Recycle and Reuse of the available resources.
Food Conservation
Natural Resources used as food for the living organisms are called Food Resources. Conservation of food resources
will help retain the nutritional value of food and avoid its wastage. It serves to feed mankind in times of adverse
conditions like war, natural calamity, food shortage due to climatic change, etc.
