Explain any 3 measures of conservation of resources
Use of alternative sources of power such as solar and wind energy. These different sources of energy are bio-friendly because they do not produce any harmful gases. We all know that those gases damage the ozone layer. They are better compared to burning fossils such as coal and charcoal. They are also cheap to use, not easily depleted and are renewable sources.
Use of biofuels and biogas. For more than a century, fossil fuels have been a major source of energy. But we need to find out alternative sources of fuel such as biofuels which are mainly from plant species as fossil fuels are depleting rapidly. They are called biofriendly and can reduce the occurrence of air pollution to a very high extent. All over the World, Liquefied Petroleum Gas (LPG), one of the most extensive sources of fuel in our homes, restaurants today. Continuous use of LPG results in the exhaustion of the oil reserves. Therefore, biogas is a good alternative. It is mainly produced from cattle dung. We must remember that biogas plants are a very good source of both biogas and manure.
Planting trees in home compounds and to prevent soil erosion. Proper shade and perfect air conditioning are mainly provided by natural trees and forests. Forests ensure that there is clean air for us to breathe thus creating a perfect air conditioner. This helps to cut down the electricity costs from the use of air conditioning appliances. This entails planting trees and vegetation to control soil erosion caused by wind and water. For the maintenance of the ecosystem, trees and vegetation are essential. Most insects, birds and some symbiotic plants also stay there as their home. Thus, it creates a cool habitat for wildlife consequently conserving wildlife altogether.
