After more than four decades of celebrating Earth Day, you鈥檇 think something would have stuck. But young Americans are less interested than ever in the environment and taking action to save nature, according to a new comprehensive study of high school seniors and college freshmen.

And it鈥檚 not for lack of trying by environmentalists. We鈥檝e deployed every hot new marketing tactic around to reach the Millennial Generation 鈥� eco-fashion shows, 鈥淩ock the Green鈥� concerts, Earth Hour, and green labeling on everything from drinks to jeans. What鈥檚 left to talk about?

People, for starters.

Environmentalists don鈥檛 talk about people much. We go on about the loss of endangered species, degraded coral reefs, dwindling numbers of sharks, and logged-out ancient forests. But we barely mention people 鈥� the biggest beneficiaries of nature. And that鈥檚 why most people tune us out.

Earth Day marks its 43rd year on April 22. Forty-three years is nothing. The Earth has survived for 4.5 billion years. It鈥檚 handled countless asteroids, oxidizing bacteria, and climate-changing volcanoes. Trust me, the Earth is going to be fine.

The real question is: are we?

Our species has been around for about 100,000 years. To put that number in perspective, consider this: If the Earth were as old as the average American, people have been around for about as long as a single night.

Yet the modern environmental movement ignores human well-being. Environmentalists don鈥檛 focus on the billions of people whose standard of living is unimaginably low and for whom the sustainable use of nature could provide a lasting way out of poverty. We don鈥檛 talk much about how nature is an integral part of all of our lives, including that of business and youth.

Instead, our rhetoric is relentlessly about 鈥渓ess.鈥� Limit your footprint. Reduce your consumption. Why are we surprised that, for the majority of American youth, protecting nature seems a joyless exercise in deprivation?

That鈥檚 no way to create social change.

This Earth Day, let鈥檚 put human well-being at the center of the environmental movement, and make explicit the value of nature to our everyday lives. Even better, let鈥檚 shift the movement鈥檚 priorities to focus on three groups who have been long neglected and yet hold the key to the future success of the environmental movement:

The rural poor, for whom nature provides the ultimate social net and provides many of basic needs; the business community, for whom sustainability is becoming synonymous with availability of natural resources, often the greatest uncertainty to growth; and youth, who 鈥撀� empowered with technology 鈥� can make saving nature a social enterprise about protecting others.

Take the Condor Biosphere Reserve outside of Quito, Ecuador. Conservationists are keen to protect it for its Andean bear and condor populations 鈥� wild animals I personally cherish watching. Yet the approach that鈥檚 clicked with Ecuador鈥檚 human population hasn鈥檛 been conservation in the traditional, fence-people-out sense. Instead, companies pay rural communities in the reserve to protect water that flows from it. In return, these indigenous communities safeguard the watershed (and the reserve) better than any park ranger could alone.

This model has such resonance that it鈥檚 now being applied in dozens of cities and watersheds around the world.

So does this mean we should ditch the name Earth Day in favor of Human Day? I鈥檒l leave that to the branding experts.

The real point is that by making environmentalism about what people really care about 鈥� our well-being, our way of life, our survival 鈥� we not only secure the environmental movement鈥檚 relevancy, but also ensure that our fragile species is nutured by a healthy and relatively resilient planet. Youth will respond to that message. So might the rest of the world.
