Measuring the ‘ecosystem services’ that the ocean provides is difficult, but an essential step to understand how best to protect marine ecosystems.

The US Supreme Court opens its 2022-2023 term with a case that could greatly reduce federal protection for wetlands. Here is what makes these ecosystems valuable.

People wouldn’t last long without the countless other species we depend on for survival.

With the world losing species at an alarming rate, a conservation biologist explains how ideas about protecting biodiversity have evolved over the past 40 years.

Radical new thinking is required to fight climate change, and ‘gross ecosystem product’ might help.

Abandoned US oil and gas wells and their associated land cover more than 2 million acres, a recent study estimates – an area larger than Delaware and Rhode Island combined.

When something is free, people use a lot of it. Economists are urging governments to compute values for natural resources – wildlife, plants, air, water – to create motives for protecting them.

People both for and against pricing biodiversity need to work together to protect the natural world.

Healthy seagrasses form underwater meadows teeming with fish and shellfish. A successful large-scale restoration project in Virginia could become a model for reseeding damaged seagrass beds worldwide.

Restoring western forests – thinning out small trees and dead wood – is an important strategy for reducing the risk of massive wildfires. But these projects aren't fast, easy or cheap.
