The National Wildlife Federation has announced that Robert Redford will be the guest of honor for its 75th Anniversary Gala and Conservation Achievement Awards Dinner on April 14.

The 74-year-old actor will be receiving the prestigious Conservationist of the Year award for his 35 years of action on environmental issues.

"As a dedicated conservationist and environmental leader, Mr. Robert Redford has focused the public's attention on the importance of developing renewable energy, safeguarding clean water, and protecting the Arctic National Wildlife Refuge, while warning against the harsh impacts of global warming," said federation President Larry Schweiger.

Said Redford, "I believe the efforts of the National Wildlife Federation are more necessary now than ever to protect our natural resources and to prepare the next generation of environmental stewards."

"I am truly honored to celebrate the Federation’s 75th Anniversary and all of their profoundly significant accomplishments," he added. "I am very moved to be acknowledged by it in conjunction with this important occasion."

The gala, which will be held in Washington, D.C., will also be honoring first lady Michelle Obama with the Special 75th Anniversary Conservation Award. NWF will recognize, among other projects, Obama's Let's Move! initiative, which seeks to curb childhood obesity through education, healthy eating habits and encouraging youth to get outside and explore the great outdoors.

It's not yet known if the first lady will accept the invitation to attend the ceremony.
