Hi John,

Time's running out to choose your digital member card when you protect our beautiful planet by joining WWF's community of monthly members during our spring membership drive, which ends on Earth Day (next Monday).

If you're ready to put your support to work in the most effective, easiest way possible, choose your exclusive digital member card and become a WWF monthly member today.

We call our monthly members WWF Heroes because they save nature! They provide crucial support for our conservation efforts and help us plan for long-lasting programs that reduce the most pressing threats to the diversity of life on Earth.

WWF Heroes make every day Earth Day. They save endangered species from extinction, stop deforestation and many other threats to nature and people, conserve oceans and other critical habitats, and solve the world's greatest environmental problems.

Become a WWF Hero now—with a $10/month donation or another amount—and protect nature all year long.

Thanks for protecting this beautiful planet,

P.S. Monday is Earth Day—and the final day of our membership drive! Become a WWF Hero today and protect the planet we love 365 days a year.

Would you prefer to make a onetime donation? We would be grateful! Every member makes a difference.
