Answer:
Humans have had a very negative impact on the water supply.
Explanation:
The water, or rather the freshwater, is found around the globe, in some places more, in some places less, thus its distribution is not equal. Despite this, there is actually more than enough water for all living organisms, including humans. However, that is the case if the water supply remains clean and in good condition, which has been becoming rarer and rarer across the globe.
Human activity, especially after the industrial revolution, has caused enormous damage to the water supplies. More and more water supplies have been polluted, often heavily, while some have been totally depleted or are on the verge to be very soon. The industry, production of electricity, garbage disposal, sewage, agricultural practices, have all led to making perfectly fine water supplies turn into water that if consumed can either cause bad illness or even lead to death. This is something that has to be a priority for the world because if the trend continoues there will soon come a situation where the majority of the world will have no water of proper quality for usage wich will be catastrophic.
