Lapatulllka [165]

Answer:

Option (C)

Explanation:

CO₂ is one of the main green house gases on earth. A small increase in its concentration can lead to significant changes on earth. When the incoming solar radiations are incident on the earth's surface, some of the energy is absorbed by the atmosphere and the earth's surface. And some of the energy from the land surface after absorption is released into the atmosphere in the form of infrared radiations. The escaping of these radiations from earth is directly dependent on the concentration of CO₂. An increase in the amount of CO₂ will not allow these IR radiations to be removed, and this will result in the global rising of the temperature, leading to catastrophic changes.

Thus, the correct answer is option (C).

bogdanovich [222]

Natural resources include fossil fuels, metal, minerals,plants, soil, sunshine, water and wildlife. Every day, we depend on and use natural  resources. They contribute to the economy, by creating energy, providing shelter, producing food and medicine and for spiritual well being.  

By protecting and conserving natural resources, we ensure that they used efficiently today and are available in the future as well. Conversing resources also ensures the health and wellness of the entire system.   The 3 principles to protect resources are:

Reduce- By making environmental friendly choices in products and reducing the amount of we consume. For example, by borrowing from friends and sharing with neighbours instead of buying things that we do not use often. By using energy efficient light bulbs and electronics, we reduce the amount of energy consumed. By using public transport and not drive cars, we reduce the carbon emissions on the road and save fuel. By bringing a bag to store groceries at the supermarket, we reduce the use of plastic bags and air pollution.  

Reuse- Items such as plastic bags , other plastic food containers and coffee tins can be repurposed into storage containers for lunch boxe and storage containers for sewing supplies, tools, machine parts and gardening seeds. Torn clothes can also be used as rags or sewed to become blankets.Broken machines parts can be salvage to be used for repairing other items.  

Recycle: Place rubbish in the right recycling bins so that items like paper bags, soda cans and plastic bottles can be recycled in facilities. Opt to purchase toilet paper, tissue paper and writing paper made from recycled papers too.  

Conserving and protecting natural resources is important so that the climate will protected and resources will be available for the future generation.
