natural gas
mining resources
resources must not be waisted
essential to find alternatives

inadequate watering systems in farming
domestic consumption
recreational spaces that consume vast amounts of water
not worry about the scarcity of water
Fresh water
one of the most threatened resource
necessary to live
serious dangers due to its consumption in developed countries
Pollution and overexploitation of aquifers
wasteful use
Fresh water: renewable and in scarce supply on our planet.
