Most land animals cannot drink salt water. Salt water is good for sea and some coastal animals and provides a home and provides nutrients for fish and other sea creatures.

All you have to do is freeze water to make it hard.
Most polar animals are coloured in some form of black and/or white. The black sides of animals make them hard to see from above -- in water, and the white sides of animals make them hard to see from below -- in water. Most animals that exist in polar environments find their food chains in water, so their camouflage colouring helps them survive. Examples are puffins, penguins and polar bears.
People are "animals". Animals can not make their own food they have to eat other animals and or plants to survive. Plants can make their own food (from air, water and sunlight) - they are the basis of all food - without plants there could be no animals.
LN2 other know as liquid nitrogen is a solution that can make water hard
Why is life so hard? just to guess
hard water can be converted to soft water by boiling, filteration etc.
Boiling hard water does not make it soft. Boiling water only removes some impurities and kills bacteria, but it does not change the mineral content that makes water hard. To soften hard water, a water softener system is needed.
Ground oyster shells will make soft water harder. Therefore, it will make hard water, harder.
Animals will only live in areas where there is enough water for them to survive. Thus, fish and amphibians can only live in bodies of water, and animals like mammals, reptiles, birds, and many insects can live farther away. In a place with very little water, it may be that only animals which can acquire all of their necessary water from food can exist. In a place with abundant water, generally there is a greater variety and population of animals.
