and rising seas.

Human intervention makes beach erosion worse!

Without A Doubt!

Students need to learn critical

thinking. Stick with the facts!

Relax … it’s only the end of the world?

Absolutely Not!

We’ll Adapt to

a

Different Earth …

Mitigation? … Cutback our

Fossil Fuel Addiction!

Green our Economy!

Sustainability! Clean Water

& Air! Healthy Kids!
