The Tasmanian tiger (or Thylacine) was a carnivorous marsupial located near the top of Australia's food chain. Halfway between a tiger and a coyote, its dog-like appearance is often used as an example of convergent evolution. It looks similar to a dog, but its genetic lineage is completely different. The thylacine's story is not a …
The Decision To Electrify Your Life
I could be one of those annoying people you love to hate. I’m vegetarian, I grow food in the backyard, and I have solar panels on my roof. I offset the natural gas I use for heating each year and keep the thermostat low in winter. I proselytize regularly about the dangers of climate change …

It's a disappointment for some. But it could also mark the start of a different future with large animals. See what you think. "What …
Putting Carbon Back Where it Belongs

A paper published in February notes without drama that “....the total carbon stored in wild mammals and birds is equivalent to roughly eight hours of current anthropogenic fossil fuel …
Wildebeest and Climate Change
Noodling around the growing literature on carbon cycling by animals, I recently came across a startling fact. More than half a century of wildebeest recovery in Africa’s Serengeti has resulted in the sequestration of enough carbon each year to offset all of East Africa’s fossil fuel emissions. Think about that for a minute. More wildebeest …

Anyone who loves wildlife in the West should pay attention to what has been going on around Yellowstone National Park. Montana’s position on wolves has, to put it delicately, taken a ‘hard turn.’ This needs to change. The 2021 Montana state legislature crafted aggressive laws to reduce the state’s wolf population. Wolves can now be …
