Not that the lobster can do anything about it, once in the pot. But we might. We’re supposed to be smarter than lobsters. We’ve committed some very stupid acts over the course of our history, but our stupidity isn’t inevitable. Here are three smart things we’ve managed to do:

First, despite all those fallout shelters built in suburban backyards during the Cold War, we haven’t yet blown ourselves up with nuclear bombs. Second, thanks to Rachel Carson’s groundbreaking book on pesticides, Silent Spring, not all the birds were killed by DDT in the ’50s and ’60s. And, third, we managed to stop the lethal hole in the protective ozone layer that was being caused by the chlorofluorocarbons in refrigerants and spray cans, thus keeping ourselves from being radiated to death. As we head towards the third decade of the 21st century, it’s hopeful to bear in mind that we don’t always act in our own worst interests.

“For everything to stay the same, everything has to change,” says a character in Giuseppe di Lampedusa’s 1963 novel, The Leopard. What do we need to change to keep our world stable? How do we solve for X+Y+Z — X being our civilization’s need for energy, without which it will fall swiftly into anarchy; Y being the finite nature of the earth’s atmosphere, incapable of absorbing infinite amounts of CO2 without destroying us; and Z being our understandable wish to live full and happy lives on a healthy planet, followed by future human generations doing the same. One way of solving this equation is to devise more efficient ways of turning sunlight into electrical energy. Another way is to make oil itself — and the CO2 it emits — part of a cyclical process rather than a linear one. Oil, it seems, does not have to come out of the ground, and it doesn’t have to have pollution as its end product.

There are many smart people applying themselves to these problems, and many new technologies emerging. On my desk right now is a list of 15 of them. Some take carbon directly out of the air and turn it into other materials, such as cement. Others capture carbon by regenerating degraded tropical rainforests — a fast and cheap method — or sequestering carbon in the soil by means of biochar, which has the added benefit of increasing soil fertility. Some use algae, which can also be used to make biofuel. One makes a carbon-sequestering asphalt. Carbon has been recycled ever since plant life emerged on earth; these technologies and enterprises are enhancing that process.

Meanwhile, courage: homo sapiens sapiens sometimes deserves his double plus for intelligence. Let’s hope we are about to start living in one of those times.
