Desalination is a costly process, and it is difficult to build. It requires expensive infrastructures. The by-product (brine) can destroy natural environments if contamination occurs. Lack of accessibility to sea water in landlocked countries, makes it limited to coastal areas.

Water soluble vitamins are expected to be polar compounds since like dissolves like. Water is a polar compound and for vitamin to be soluble, it has to be polar as well.

Fat is lipid, and lipids contain a hydrophobic tail and hydrophilic head, thus, fat soluble vitamins are expected to be non-polar to blend into the hydrophobic fats.

a. By hanging your laundry to dry, electronic dryer is not used, hence lesser electricity is used. Usage of lesser electricity, lower electricity consumption means lower fuel consumption, this will result in a lesser need for burning of coal for fuel.

b. There will be lesser use of personal vehical, means lesser auto mobiles on road, reducing pollution by cars.

c, d. Both reduced the amount of electricity required, conserving energy, reducing fuel consumption from power plants and thus lesser pollution from power plants.

e. By increasing locally grown production, the demand for imported produced food decreases hence decreasing factory outputs lowering pollution from factory.

a. Coal fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. While burning coal, incomplete combustion may happen, this will result in production of soot, carbon monoxide and many other harmful gases. This causes higher possibility of haze.
