What year will we run out of food?

Is Earth gaining or losing water?

The Earth will slowly lose water unless it is hit by an ice-rich meteor/asteroid. Water can be lost by simply having water gas molecules leaving the atmosphere fast enough to escape gravity (any gas can be lost like this). However, water is lost very slowly. … Water readily condenses into the atmosphere.

How long will it take for the Earth to run out of water?

Within three decades, almost 80% of the lands that depend on groundwater will start to reach their natural irrigation limits as the wells run dry. In a world of increasing extremes of drought and rainfall, driven by rising global temperatures and potentially catastrophic climate change, the water will start to run out.

How old is the water we drink?

Will we run out of freshwater?
