Over the years, I have relied on a few journalists to help me navigate my way through the forces and events that resemble a fog in everyday life, at least in mine. Tom Friedman is one of them. He is probably unsurpassed in terms of scope and depth of knowledge and understanding of countries in the Middle East. I also very much admire his integrative thinking skills. Here is a brief excerpt from a recent column for The New York Times in which he addresses several issues of great interest to me.

I participated in the World Parks Congress in Sydney last week and learned a new phrase: “a black elephant.” A black elephant, explained the London-based investor and environmentalist Adam Sweidan, is a cross between “a black swan” (an unlikely, unexpected event with enormous ramifications) and the “elephant in the room” (a problem that is visible to everyone, yet no one still wants to address it) even though we know that one day it will have vast, black-swan-like consequences.

“Currently,” said Sweidan, “there are a herd of environmental black elephants gathering out there” — global warming, deforestation, ocean acidification, mass extinction and massive fresh water pollution. “When they hit, we’ll claim they were black swans no one could have predicted, but, in fact, they are black elephants, very visible right now.” We’re just not dealing with them at the scale necessary. If they all stampede at once, watch out.

No, this is not an eco-doom column. This one has a happy ending — sort of. The International Union for Conservation of Nature holds the parks congress roughly every 10 years to draw attention to the 209,000 protected areas, which cover 15.4 percent of the planet’s terrestrial and inland water areas and 3.4 percent of the oceans, according to the I.U.C.N.

I could have gone to the Brisbane G-20 summit meeting, but I thought this was more important — and interesting. A hall full of park exhibits and park rangers from America, Africa and Russia, along with a rainbow of indigenous peoples, scientists and environmentalists from across the globe — some 6,000 — focused on one goal: guarding and expanding protected areas, which are the most powerful tools we have to restrain the environmental black elephants. How so?

It starts with a simple fact: Protected forests, marine sanctuaries and national parks are not zoos, not just places to see nature. “They are the basic life support systems” that provide the clean air and water, food, fisheries, recreation, stable temperatures and natural coastal protections “that sustain us humans,” said Russ Mittermeier, one of the world’s leading primatologists who was here.
