FRESH WATER ON EARTH

The lakes in Maine are vast reservoirs of culture and tradition that sustain the rural heart of this State.  Without them, the communities that make up the landscape of Maine would either not exist or would be mere fractions of their vibrant selves. What we do as we learn about how our lakes work and how we treat them is only part of a much larger picture that extends well beyond the borders of Maine.  Let‘s look at our lakes from a global perspective.

 If we were on a space shuttle, we’d see a blue and green marble against a backdrop of absolute black space.  The shades of greens and brown (land masses) make up 25% of what we see…the blue oceans make up 75% .  It looks so plentiful for the 6.2 billion humans whose numbers grow by 80 million each year.

 And this is Earth’s freshwater breakdown.

About 69% is tied up in the permanent arctic polar caps and glaciers.

Almost 30% is in groundwater aquifers, most of which are very deep and inaccessible.

The remaining 1.2% is composed of permafrost (.8%) and surface and atmospheric water (4%). Lakes hold~67% of surface and atmospheric water.

We must continue to increase awareness of the importance of sustainable freshwater use.
