WATER - essential for all life: THINK before you open the tap every time;

People need to become more aware/mindful, of how limited fresh water is, and how fast
shut tapoff while brushing teeth; rinse dishes in pan of water, not under running tap; use irrigation instead of spraying water on lawns (and evaporating uselessly).
We are using/wasting it. Use smaller capacity tanks to flush toilets...Crops livestock (if one HAS to eat animals), fishes, etc., can be raised far more efficiently than done at present; run-off from households, industrial uses, frivolous uses ('mist spraying'/cooling for example, in Arizona); swimming pools, lawn watering, all are terribly inefficient, blatantly wasteful uses of water. We really need to CREATIVELY rethink our H2O consumption/use.
