Groundwater is a limited resource, yo!

by Shana on Sep. 24th, 2010

According to a recent study, the rate of groundwater depletion more than doubled since 1960. Groundwater provides most of the water we use in our homes and fields, including drinking water. It's estimated that groundwater depletion accounts for about 25 percent of sea level rise each year because most of the removed water evaporates and falls into the ocean. To compound matters, hard surfaces such as concrete prevent rainwater from replenishing underground reservoirs and aquifers.

About 70 percent of the world's freshwater is frozen in land-based ice sheets and glaciers, which are also melting into the ocean. So, cisterns? Desalination plants? How do you think we'll get freshwater when the frozen stuff is all that's left?

I was surprised to learn that 70% of the world fresh water is frozen.
