Water
We take water for granted. It is vital for life. Monetary greed looks for the immediate outcome instead of the long term repercussions.
Agriculture, though needed to feed the almost 7 billion people walking this planet, consumes large amounts of water for irrigation without thought of the runoff damage from pesticides and animal waste.
Industry consumes water as solvent, discharging pollutants into waterways.
Pharmaceutical dependency consumed by humans effects aquatic life.
Lack of humanity, bypassing infrastructural repairs for the safety of potable water like in Flint, or access to safe drinking water from poor sanitation in many countries around the globe.
We need to act today for tomorrow. There is no substitution for water.
