Desalination requires water to be converted to steam. However, water has high specific heat capacity(4200KJ/mol), so a large amount of energy is required to boil the water.
As such this method will not be economical.

Water-soluble vitamins are polar because “like dissolves like.” Water is polar and if something is water-soluble than it is polar too. Fat-soluble would not be polar.

a. Electricity(dryer)->powerplant(burns coal/fossil fuel)->emit SOx
b. Walk/bike/public transport->reduces usage of car->reduces emission of NOx
c. Electricity(dishwasher & washing machine)->powerplant->emit SOx
d. Lack of insulation results in more energy loss to the environment, additional electrical energy is required to maintain water temperature
e. Locally grown food reduces the need for transportation(by air/water/land). Thus reduces NOx.

a. Coal-fired plants releases SOx, which reacts with water in the atmosphere. Sulfuric acid is thus formed, and these tiny droplets of H2SO4 form aerosols which do not absorb sunlight. They reflect light and reduces visibility.

b. Assuming that the average pH of rainfall is 5.5, the rainfall in the park would have a pH of 4.5.
