Answer 2

Answer:

Recycling

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its virgin or original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing: energy usage, air pollution (from incineration), and water pollution (from landfilling).

Save water

Water is inextricably linked to energy and climate change. Energy is required for pumping and treating water that we get at home. Pumping and treating wastewater is energy intensive. Conservation of water indirectly conserves therefore, conserve energy and reduced greenhouse gas emissions.

Climate change will also impact freshwater supply. Global warming is resulting in shifting rainfall patterns, an increase in the number of dry days, torrential rainfall over short periods of time, and extreme weather events, all of which increase the likelihood of droughts and floods. It, in turn, will affect food supplies and human health. Water is expected to be a major source of conflict in future because demand is soaring and freshwater reserves are severely stressed. Plummeting groundwater resources in many regions and inefficient use of water is a matter of serious concern.

Despite adequate rains, we face a shortage of water for drinking, agriculture, industry and sanitation. It even leads to conflicts among neighbours – people and provinces. Wastage of water can be avoided through various ways. Rainwater harvesting can recharge our lakes and ground aquifers. Farmers can avoid excessive flooding of fields. In our houses, we have plenty of scope for reducing consumption. Pollution of water by the discharge of wastes is itself a serious problem, as cleaning it for reuse by humans requires lot of efforts and energy. .

Solar energy

Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world. Solar technologies can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use. .
