Less signaling, more doing is needed on the environment in Denver | Colorado Newsline
So far in 2025, Denver’s City Council has done more to signal its disapproval of poor air quality than actually tackle it.

Signaling disapproval of air pollution, Denver City Council rejected an asphalt contract w/ Suncor. Yet in 2025 they passed harsh regulations on micromobility & are potentially widening Pena Blvd — both bad for air.

This is the single biggest problem with our food system. It is absurdly inefficient. Less than half of what we grow ends up on our plates.

Fewer than half the calories grown on farms now reach our plates
In 2020, the world produced more than enough calories to feed the global population, but only half of those calories reached people’s plates due to rising meat and biofuel production

I find nothing so offensive as a neo-nazi sympathizer opportunistically using anti-semitism to further xenophobia & intolerance. Disgusting on so many levels.
Trump administration officials this week reportedly cited the Boulder attack as justification for his reimplementation of a sweeping travel ban that falls largely on Arab- and Muslim-majority countries.
After Boulder attack, Trump revives Muslim travel ban with targeted changes
President Donald Trump will tailor the travel ban after an Egyptian national was arrested in a burn attack in Boulder, Colorado.

The answer to this conundrum is inherent in the author’s stats:
To feed humans, ag production must expand by 50% by 2050.
Currently, 3/4 of the world’s ag land supports livestock.
Replace the livestock land with plant proteins! Emissions & land use will decrease, available calories will increase.

Clean energy could power everything on the planet and we’d still have a major climate problem. An essay excerpted from Michael Grunwald’s forthcoming book on the challenge of feeding our hot and hungry Earth:

Yes, sidewalk scooter riding in downtown Denver is bad. But the street infrastructure, even with welcome additions of protected lanes, still soooo heavily favors motor vehicles, it makes no sense to discourage micromobility without equal effort to build safe access for it.
"Scooter ordinance" passes unanimously in Denver City Council, getting scooters off sidewalks
Denver City Councilman Chris Hinds, said new technology will be in place to make sure e-bike and scooter riders stay off the sidewalks and don't finish their ride until they can park in a corral.
