Dear John,

There are powerful solutions to our greatest environmental challenges, and individual actions can lead to big change when we move together.

One critical area where you can make a difference is in protecting Earth’s precious freshwater systems—the rivers, lakes, and streams that sustain all life. Pledge to give an hour for Earth by choosing one of these high-impact activities:

1. Track your water usage for a day. Come up with a plan and commit to one way to use less water in your daily life.

2. Explore your local waterways. Observe the biodiversity that thrives in and around the water and note how the area supports your community.

3. Evaluate the “water footprint” of the food you eat. Identify ways to make changes in my diet to conserve water.

4. Or choose another way to do something positive for the planet—and the water on which life depends.

Your commitment to giving just one hour for Earth can lead to significant change and inspire others to do the same. Together, we can create a healthier and more sustainable planet.

Sincerely,
