Worry About Air Pollution, Not Just Climate Change

October 29th, 2009

Yes, global warming is a big deal and a big challenge. But sometimes I get so frustrated by conservation and environmental NGO’s for not being able to chew gum and walk at the same time — in other words, for failing to appreciate the real lesson of greenhouse gas emissions. The real lesson is there […] More

Why Do We Fall in Love with Nature? And Does It Mean Conservation is in Trouble?

October 7th, 2009

I have made a habit of asking ardent supporters of conservation — from members of The Nature Conservancy’s board of directors to the volunteer docents at a neighborhood nature reserve — why they care about conservation. The answer, almost inevitably, is some memorable or inspiring experience in nature. So what will happen if future generations […] More

When Climate Change Demands a New Nature, Will We Be Ready?

September 30th, 2009

In 50 years, many parts of the world will be unrecognizable because of climate change, population growth, shifting agriculture, new energy sources, hundreds of new cities and imperiled water supplies. The pressures of the climate crisis, coupled with the global recession, are pushing the conservation movement to reexamine many of its core assumptions. There is […] More

Scientific Illiteracy Threatens Our Future…and It’s Scientists’ Fault

August 3rd, 2009

You have all heard the statistics that nearly one-half of all Americans do not think humans evolved from apes, and that about one in five American adults think the sun orbits the Earth. Scientific illiteracy is not just a matter for elitist smugness — it can endanger the innocent. For example, there is a movement […] More

Should Protected Areas Be Reexamined?

May 19th, 2009

I am going to commit conservation heresy and ask out loud: Should the conservation movement be proud of the 108,000 protected areas around the world it has thus far helped establish? I have many reasons for asking that question, but among those reasons is certainly Mark Dowie’s recently published book Conservation Refugees: The Hundred-Year Conflict […] More

Children and Their Carbon Legacy: A Way to be an Eco-Hero?

March 11th, 2009

There are carbon calculators galore on the web — including The Nature Conservancy’s very own. These calculators allow you to figure out how your activities and lifestyle contribute to the carbon emissions that are responsible for the climate disruption the world now faces. Rarely, however, does one see any discussion of what population growth means […] More

Climate Change: Adapt or Die

January 29th, 2009

If you stop 100 people on the street and ask them about climate change, 87 of them would know something about it, according to polls. But if you asked the same 100 people if they’ve ever heard of “adaptation to climate change,” I bet you’d get 100 blank stares. That’s a problem. For sure, we […] More

Can Nature’s Value Alone Save Nature?

January 21st, 2009

You cannot read about conservation these days and not notice the astonishing zeal for ecosystem services as a new conservation strategy. (The February 2009 special issue of the Ecological Society of America’s journal Frontiers of Ecology and the Environment is a good case in point, although it’s not online yet.) The idea behind ecosystem services […] More

World-Class Environmental Scientists Take Leadership Positions on Obama’s Team

January 16th, 2009

I follow politics, and love to argue and discuss the subject with friends. But usually conservation science and scientists are on the outside looking in – external voices trying to influence federal policy. That situation, however, just changed. President-elect Barack Obama has appointed two of the United States’ most prominent environmental and conservation scientists to […] More
