Litterbug

On Saturday, Earth Day, I went for a run. About a mile in, I came upon a bald, middle-aged man. He wore a leather jacket and a Bluetooth headset. I was perhaps twenty feet from him when he chucked a crumpled plastic bag on the ground. Then he got on his bicycle and started peddling […]

Reading Sci-Fi with Astrobioloigist David Grinspoon

David Grinspoon is a comparative planetologist and an astrobiologist. He’s also a big book nerd, and his love for both fiction and nonfiction are proudly on display in his own new book, Earth In Human Hands: Shaping Our Planet’s Future. Grinspoon’s book uses insight from the study of the other planets in our solar system […]

Don’t Think of a Mammophant

  Let’s talk about de-extinction. Actually, let’s not. Let’s talk about what the as-yet-unrealized technology known as “de-extinction” really is, which is the creation of hybrid organisms using genetic material from both extinct and extant species. Last month, a team of scientists announced that a hybrid elephant-mammoth embryo—”more like an elephant with a number of mammoth traits,” […]

Creating With Nature: Ice Ornaments

If it is still freezing hard during the night where you live, you can try this easy and fun art project. Find some paper plates, cups, tupperware containers, anything with an interesting shape that you can get ice out of in one piece pretty easily. I like the paper plates because you can kind of […]

The Quaking Giant

(Hey, I just thought you might like to imagine a pile of 10,000 bears.) This tree is the […]

Why Rachel Carson Still Matters

On Monday, the Trump administration instructed U.S. Environmental Protection Agency staffers to freeze all of the agency’s grants and contracts—cutting off financial support for many state and tribal environmental protection programs. (Staffers were also told not to discuss the freeze with anyone outside the agency, but the news was quickly leaked to both ProPublica and the Huffington […]

The Freshwater Bullies of Gatun Lake

The crocodiles should not be a problem. Yes, the population has spiked after being placed under protection, and there have been some attacks recently. But those attacks tend to happen when somebody steps right into the water. The crocs all hang out in the shallows. Stay out of the water and you should be fine. […]

Reason for Hope

I joined a film crew several years ago in Chilean Patagonia where we put together a  flick opposing dams along the turquoise rivers of the Aysén region. At the time, stopping the advance of some of the biggest investors in the world seemed impossible. But soon more films were made, protests ignited across the country to save […]
