Question

What are the meanings of following symbols? Write your role accordingly?

Answer 1

Symbol 1 represents recycle. This sign is seen on various packaged food materials. Recycling is the process in which a substance that has been discarded is reprocessed to make the same or a different substance. It is one of the methods to conserve our environment, for example recycling of paper saves several others trees from being cut down. Also, chemicals that are produced at the time of manufacturing paper are directly released into rivers and lakes. Therefore, recycling of paper will not only prevent deforestation but also prevent water pollution.
Symbol 2 represents water conservation. Water conservation refers to the act of conserving water with the help of various methods such as rain water harvesting. Conservation of water is essential for maintaining a proper hydrological cycle, ensuring timely rainfall and maintaining the availability of fresh water in rivers and other sources. Conservation of water is essential for securing food grain production and sustaining various life-forms. Water can be conserved by various methods. The most effective means of conserving water is rainwater harvesting, which involves collecting rainwater and storing it for further use. Water can also be conserved by checking our day-to-day habits and ensuring that there is no wastage of water. Innovative irrigation techniques such as drip irrigation also help in water conservation to a great extent.
Symbol 3 represents solar pannels. Solar energy can be harnessed with the help of solar cells. Several solar cells are connected together to form a solar panel. Solar panels devices are used to convert thermal energy of sun into electric energy. There are various reasons for which solar energy is being prefered over other sources:

• being a tropical country India receives abundant sunlight throughout the year as the number of sunny days across a large geographical portion of country is around 300.
• it requires less investment in infrastructure as compared to other forms of energy.
• solar energy can be utilised for rural electrification and irrigation through solar powered water pumping system.
• it will eventually reduce the dependance upon fossils fuels hence will help in the conservation of environment.
