Explained

On whose green Earth?

Are we supposed to take care of the planet or should it take care of us? Willis Jenkins explains how religion shapes the conflicting views over climate change and other environmental issues.

Climate change can set the stage for violence

Worsened by global warming, drought and other environmental stressors play a role in fanning the flames of civil conflicts

The dazzling history of solar power

PODCAST: Once fringe and futuristic, this renewable energy shines brightly today as a cheap and efficient source of energy. Still, it remains controversial ­— for much different reasons. (Season 1/Episode 3)

Will the food of the future be genetically engineered or organic? How about both?

Feeding the planet — now and tomorrow — is no small task. Plant biologist Pamela Ronald says sustainability means using every tool in the toolbox.

The race against radon

Scientists are working to map out the risks of the permafrost thaw, which could expose millions of people to the invisible cancer-causing gas

Fighting fire with fire ... and fauna

Climate change is aggravating the seasonal burns that Australia has always known. They won’t be snuffed out, but new ecological strategies may help.

Make electric vehicles affordable for the rest of us

OPINION: EV subsidies are poorly designed and mostly benefit the rich. Some simple changes could make them more effective and equitable.

Pollution evolution: The little fish that could

Where other species succumbed, the killifish survived contaminated habitats. It’s a finding that could help researchers understand environmental risk factors for humans.

Russia is guilty of ecocide

OPINION: All perpetrators of environmental destruction should be held accountable

The fight against an invasive fish in California’s Clear Lake

VIDEO: Can removing carp help the lake’s native fish and keep toxic algal blooms in check?  

To help birds and insects, cultivate native gardens

Entomologist Doug Tallamy explains how filling our yards with local plants can provide our feathered friends with a caterpillar buffet

How wind turbines could coexist peacefully with bats and birds

As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.

Does it work to pay people not to cut the forest?

Evidence that the approach helps to save trees, preserve ecosystems and reduce carbon emissions is often hard to come by. But it can succeed if it’s done right, says an economist.

The quest to understand tornadoes

Scientists are still grappling with how and why violent twisters form. Will new technology and computing power help?

Can a fire-ravaged forest of Joshua trees be restored?

VIDEO: In August 2020, the Dome Fire burned more than 40,000 acres of the iconic species’ range in the Mojave Desert, leaving a graveyard of blackened trees. A massive replanting effort now underway hopes to return life to the fragile ecosystem by boosting numbers of the climate-threatened plant.

The photosynthesis fix

As world food needs rise, so does the need for faster, more efficient plant growth. Bypassing an error-prone enzyme is one way to do it.

What the world can learn from Britain’s humble hedge

Hedgerows were historically planted as barriers between fields, but in a human-dominated world, they are critical havens, corridors and connectors for wildlife

Getting lab-grown meat — and milk — to the table

Beef, chicken and dairy made from cultured cells could offer a smaller footprint than conventional farms. Companies are working on scaling up and bringing prices down.

New Zealand’s quest to save its rotund, flightless parrots

DNA sequencing, GPS tracking and tailored diets are slowly restoring the endangered kākāpō

Baking resilience into the food system
