1) Normally we have Oxygen amounting to 1/5th of air and Nitrogen to 4/5th. The Oxygen is used for respiration by people, plants, animals, and all organisms. The Nitrogen is fixed by bacteria to produce ammonia. During the lightning too ammonia is produced. That is used in producing Amino acids and Nucleotides. They are the nutrition for the plants.
If now Oxygen amounts to 4/5 of air and Nitrogen only to 1/5, then people will be healthier as more Oxygen is available. Asthmatic people will heal faster. But the nutrition for the plants may be reduced. Perhaps the life of plants may be affected to some extent. For some thousands of years people will do better.
2) water is used for washing clothes, houses, materials etc, for brushing, bathing that is for cleaning in general.
Water is used for cooking food, quenching thirst, cooling air or houses. Water keeps us alive. Water is used for industrial purposes to produce many chemical compounds. Water is used to produce electricity and nuclear energy. Water is used to prepare various chemical solutions, and paints. Water is used for sports also.
3) Conservation of water means to collect water that is available in our region from the ground, rivers, canals, lakes or through rain directly. There are many methods like making ponds, rain water harvesting etc. Growing plants and trees also helps conserve water. Constructing underground water tanks is also a method.
4) Potable water means water that is fit for drinking purposes. It is clean and germ free. Water is made potable by filtering using various filtering methods. Reverse osmosis methods are effective and commercially used these days. We can also boil water and collect the condensed water which is potable.

Answer:
Explanation:
The consequence of having 4/5 oxygen and 1/5 nitrogen in air would have been that earth would not have supported this kind of live and there would have been no balance of air and no photosynthesis.
