This year marks the 40th anniversary of the Clean Water Act, and while some great progress has been made, there are still many rivers which are endangered, including one flowing through our nation's capital.

Meet the Whanganui. You might call it a river, but in the eyes of the law, it has the standings of a person.

Modifications to the $3.5bn project have been made to address environmental concerns, but it may not deflect criticism.

From its tiny source to the Houses of Parliament, here are glorious photos of the River Thames.

A beautiful video by photographer Pete McBride shows how this epic and ancient river is now the most endangered in the country.

"It was cool to be in the right place at the right time," says Dr. Sciascia.

Forty years ago, activists blocked plans to dam the Buffalo River, eventually getting Congress and President Nixon to designate the river as America's first National River. Now, a factory hog farm is putting one of Arkansas' most beautiful spots at risk.

The River Thames has inspired artists throughout the ages; here's a modern take on it.

If a country is a body, rivers are its arteries through which vital blood flows. We must revive our waterways before more damage is done.

The Nature Conservancy teamed up with two artists to create a habitat-enhancing sculpture made from natural materials.

Data is not just for the internet giants; using remote laser-sensing technology, it can generate lovely maps of a river's long-past history too.

Research reveals that rivers deliver up to 4 million metric tons of plastic debris to the sea every year, with up to 95% coming from just 10 of them.

Rivers are people too, you know.

The levels were so high that scientists are revising up their estimates for global marine microplastic pollution.

A new study looks at how AVs are part of a much bigger picture of how we get around.

The car changed the design of our houses; the AV will change our houses and the way we live.

Phil Levin thinks it will change real estate completely; Christian Wolmar thinks it is ludicrous tech nerd fantasy.

Perhaps AVs should have their own lower speed limits until they figure this all out.

They want to build beacons into bikes. Will implants in pedestrians be next?

Judging from what I am reading all over the political map, I suspect that autonomous cars are the new Juiceroo.

On National Walking Day, a look at how putting cars first kills people who walk and drive.

A recent patent shows some of the thinking about fully autonomous cars, which might look nothing like cars do now.

They are going to be autonomous taxis. Is this a good idea?

Self-driving cars will likely be big autonomous mobile home theaters.

It may be decades before AVs are good enough, so in the meantime everyone will have to keep out of their way.

In which we learn a new and useful word: techno-chauvinism.

We are wasting too much time, energy and money on autonomous vehicles. We know what to do and it's not AVs.

In Ottawa, Canada, self-driving cars are being touted as a reason to delay transit investment.

The 107 million tons of grain that went to U.S. ethanol distilleries in 2009 was enough to feed 330 million people for one year at average world consumption levels. More than a quarter of the total U.S. grain crop was turned into ethanol to fuel cars

After several decades of Lrapid rise in world grain yields, it is now becoming more difficult to raise land productivity fast enough to keep up with the demands of a growing, increasingly affluent, population.

Few industrialists in recent times have done more to imperil environmental protections and public health than the Koch brothers. The force behind Americans for Prosperity and Koch Industries have galvanized

Kidney failure is killing sugarcane workers in Central America who supply sugar for both our sweet tooth and demand for ethanol.

An ethanol production mandate could be in conflict with efforts to reduce the Gulf Coast dead zone.

There is an election coming up and the farm vote matters.

The rare metal is now worth US $1,700 an ounce.

This poetic, one-of-a-kind urn floats on the water while slowly returning cremated remains to nature.

Climate crisis? What climate crisis?

This competition for the best environmental photography never fails to be interesting and professional.

It gets people in better shape using less equipment and energy.

It creates as much CO2 as a million transatlantic flights. Why isn't this a bigger deal?

There is a day for everything, and today we celebrate ride sharing.
