What does it mean to do the greatest good for the greatest number? When the Los Angeles Aqueduct opened in 1913, it rerouted the Owens River from its natural path through an Eastern California valley hundreds of miles south to LA, enabling a dusty town to grow into a global city. But of course, there was a price. Today on the show: Greed, glory, and obsession; what the water made possible, and at what cost.

The U.S. is the largest exporter of natural gas in the world. And Louisiana's Gulf Coast is where much of America's natural gas is piped in to be liquified for export. Over the last twenty years, liquified natural gas (LNG) has been heralded as a clean and efficient "bridge fuel" for nations transitioning away from coal and oil, towards a future of renewable energy. But the promise of LNG has not reflected reality. In today's episode of The Sunday Story, WWNO reporters Halle Parker and Carlyle Calhoun talk about the impact of the LNG export industry on Louisiana's Gulf Coast. And they follow the supply chain of LNG all the way to Germany and Japan. To hear more of Halle and Carlyle's reporting on LNG, listen to their three-part series, "All Gassed Up," on the podcast Sea Change from member stations WWNO and WRKF. Part One: The Carbon Coast Part Two: The German Connection Part Three: The Sugar Daddy of LNG Learn more about sponsor message choices: podcastchoices.com/adchoices NPR Privacy Policy

Generally, we at Short Wave are open-minded to the creepies and the crawlies, but even we must admit that leeches are already the stuff of nightmares. They lurk in water. They drink blood. There are over 800 different species of them. And now, as scientists have confirmed ... at least some of them can jump! Interested in more critter science?

More than a hundred years ago, a British engineer proposed linking two rivers in India to better irrigate the area and cheaply move goods. The link never happened, but the idea survived. Today, due to extreme flooding in some parts of the country mirrored by debilitating drought in others, India's National Water Development Agency plans to dig thirty links between rivers across the country. It's the largest project of its kind and will take decades to complete. But scientists are worried what moving that much water could do to the land, the people — and even the weather. Host Emily Kwong talks to journalist Sushmita Pathak about her recent story on the project. Read Sushmita's full story here. Interested in more science stories like this?

Every year for two weeks between mid-May and mid-June, Congaree National Park in South Carolina is home to a fairy-tale-like display of flashing lights. These rhythmic performances happen all because of thousands of fireflies, flashing their belly lanterns at exactly the same time. According to the National Park Service, there are just three types of these synchronous fireflies in North America, making the experience all the more magical for the lucky visitors who get the chance to see them. Firefly scientists and enthusiasts hope these displays in places like Congaree will inspire people to care about other kinds of fireflies, also known as lightning bugs, in the U.S., which are not as well-studied – or well-protected – as synchronous ones. Some community scientists are already taking on this mission with projects like the Firefly Atlas, where volunteers can help survey for fireflies and report sightings. This story was originally reported for NPR by science correspondent Pien Huang. Read Pien's full story here. Want more of the science behind wildlife wonders? Email us at shortwave@npr.org.

About ten years ago, science writer Ferris Jabr started contemplating Earth as a living planet rather than a planet with life on it. It began when he learned that the Amazon rainforest doesn't simply receive the rain that defines it; rather, it helps generate that rain. The Amazon does that by launching bits of biological confetti into the atmosphere that, in turn, seed clouds. After learning this, he began looking for other ways life changes its environment. That led to his new book Becoming Earth: How Our Planet Came to Life. He talks to host Regina G. Barber about examples of life transforming the planet — from changing the color of the sky to altering the weather. Have a story about the environment you'd like us to cover?

The National Oceanic and Atmospheric Administration is predicting a record number of hurricanes this season, which began on June 1 and runs through Nov. They're forecasting anywhere from 17 to 25 storms in the Atlantic basin, including at least four major hurricanes. Scientists think this storm activity could be due to strong winds, warmer ocean temperatures and a scientific mystery unfolding in the Atlantic. Questions about hurricanes or other weather disasters?

Wildlife trafficking is one of the largest and most profitable crime sectors in the world. The illegal trade estimated to be a multi-billion dollar industry. On a high level, that illegal trade causes problems for everything from global biodiversity to local economies and the balance of entire ecosystems. And on the immediate level, authorities are tasked with caring for confiscated animals and placing them in long-term care facilities. One network launched last year by the U.S. Fish and Wildlife Service and the Association for Zoos and Aquariums hopes to help. And with wildlife trafficking surging globally, the organizations are now in talks to expand the program to other parts of the country.

June 6, 1944 the Allied Forces stormed the beaches of Normandy and took the Nazis by surprise in the largest sea-to-land invasion in history. This would be remembered as D-Day and would ultimately lead to the end of World War II in Europe. However, this planned attack wouldn't have been possible without deep knowledge of ocean tides! We get into the whole story, including why tides sit at the intersection of astronomy and marine ecology — and why understanding tides are key to a greener future.

Baobabs are sometimes called the "tree of life" with their thick trunks, crown of branches and flowers that only open at twilight. But theories about their geographic origin was divided among three places: the savannas of sub-Saharan Africa, the Kimberley region of western Australia and the dry forests of the island nation of Madagascar. To solve this mystery, a global research team led by scientists at the Wuhan Botanical Garden at the Chinese Academy of Sciences examined high-quality genomic data from all eight baobab species.

Wildlife ecologists have seen white-tailed deer expanding their range in North America over many decades. And since the early-2000s these deer have moved north into the boreal forests of western Canada. These forests are full of spruce and pine trees, sandy soil and freezing winters with lots of snow. They can be a harsh winter wonderland. And ecologists haven't known whether a warmer climate in these forests or human land development might be driving the deer north. A recent study tries to disentangle these factors – and finds that a warming climate seems to play the most significant role in the movement of deer. Read more in the journal Global Change Biology.

Today, we're going full nerd to talk about a new board game — Catan: New Energies. The game's goal is simple: Build and develop a modern-day island without catastrophically polluting it. Although the concept mirrors the effects of climate change, those words don't actually appear in the game. NPR correspondent Nate Rott talks to Emily about the thinking behind the new game and how the developers hope it can start conversations around energy use and pollution.

Ten years ago, Flint, Mich. switched water sources to the Flint River. The lack of corrosion control in the pipes caused lead to leach into the water supply of tens of thousands of residents. Pediatrician Mona Hanna-Attisha recognized a public health crisis in the making and gathered data proving the negative health impact on Flint's young children. In doing so, she and community organizers in Flint sparked a national conversation about lead in the U.S. water system that persists today. Today on the show, host Emily Kwong and science correspondent Pien Huang talk about the state of Flint and other cities with lead pipes. Efforts to replace these pipes hinge on proposed changes to the EPA's Lead and Copper Rule. Have questions or comments for us to consider for a future episode?

NPR's Tom Dreisbach is back in the host chair for a day. This time, he reports on a story very close to home: The years-long battle his parents have been locked in with the local wild beaver population. Each night, the beavers would dam the culverts along the Dreisbachs' property, threatening to make their home inaccessible. Each morning, Tom's parents deconstructed those dams — until the annual winter freeze hit and left them all in a temporary stalemate. As beaver populations have increased, so have these kinds of conflicts with people...like Tom's parents. But the solution may not be to chase away the beavers. They're a keystone species that scientists believe could play an important role in cleaning water supplies, creating healthy ecosystems and alleviating some of the effects of climate change. So, today, Tom calls up Jakob Shockey, the executive director of the non-profit Project Beaver. Jakob offers a bit of perspective to Tom and his parents, and the Dreisbachs contemplate what a peaceful coexistence with these furry neighbors might look like.

Roughly 196 million tons of fish were harvested in 2020, according to the Food and Agriculture Organization of the United Nations. The organization also notes that the number of overfished stocks worldwide has tripled in the last century. All of this overfishing has led to the decline of entire species, like Atlantic cod. Enter the Monterey Bay Aquarium's Seafood Watch. It and other free guides give consumers an overview of the world of fish and seafood, helping people to figure out the most sustainable fish available to them. With the help of Life Kit's Clare Marie Schneider, we figure out how to make informed decisions about what we eating – whether that's at a restaurant or the local supermarket.

The Panama Canal has been dubbed the greatest engineering feat in human history. It's also (perhaps less favorably) been called the greatest liberty mankind has ever taken with Mother Nature. But due to climate change, the Canal is drying up and fewer than half of the ships that used to pass through are now able to do so. So how did we get here? Today on the show, we're talking to Cristina Henriquez, the author of a new novel that explores the making of the Canal. It took 50,000 people from 90 different countries to carve the land in two — and the consequences of that extraordinary, nature-defying act are still echoing through our present.
