All the Great Lakes are at, or close to, record highs. But it is us, not the water, that needs to move out of the way.
Should lakes, rivers and other resources have legal rights? New Zealand, Ecuador and other countries have taken this step. Now Toledo, Ohio is a US test case.

What would you pay to keep trash off your favorite beach, or pollution away from a national park? Economists can tease these values out of our travel choices and use the numbers to help make policy.
Scientists have mapped a huge dead zone in the Gulf of Oman, without enough oxygen in the water to support life. This Speed Read explains why dead zones form in waters around the world.
Nitrogen and phosphorus are polluting US waters, creating algae blooms and dead zones. New research confirms that voluntary steps are failing in the Gulf of Mexico and unlikely to work in Lake Erie.
The same conditions – ultimately tied to nutrient runoff – that created the damaging toxic blooms and dead zones in US waterways of recent years are forecast to return this year.
