# Pollution Runoff Causes Entire Lake to Turn Bright Pink

## Pink Lake

A lagoon in the southern Patagonia region of Argentina has turned a strikingly bright shade of pink, [*Agence France-Presse* reports](<https://www.ndtv.com/world-news/pollution-turns-argentina-lagoon-bright-pink-2494689>), the result of chemicals being dumped by a nearby plant.

The Trelew industrial park nearby uses sodium sulfite, an anti-bacterial, to preserve prawns for export. Sodium-sulfite runoff from the plant is now contaminating the Chubut river that flows into the Corfo lagoon, according to *AFP, in* yet another example of processing plants using natural waterways as their dumping grounds — a grim and horrifying pollution event.

"Those who should be in control are the ones who authorize the poisoning of people," environmental activist Pablo Lada told *AFP*.

## Pollution Party

Local residents were getting fed up with a continuous stream of trucks from the industrial park passing through their town called Trelew. The trucks were delivering fish waste to treatment plants just outside of the city and had to pass through town to get there.

So residents started blocking trucks from passing through town in protest. "We get dozens of trucks daily, the residents are getting tired of it," Lada told *AFP*.

As a result of the blockade, provincial authorities started allowing factories to dump their waste into the lagoon — instead of disposing the waste at the treatment plants in the outskirts of Trelew.

Sodium sulfite is a common antioxidant and preservative. It is predominantly used in the [pulp and paper industry](<https://www.icis.com/explore/resources/news/2008/03/10/9106600/chemical-profile-sodium-sulfite/>), but can also be added to stop dried fruit from discoloring and preserve meats, including prawns.

Despite the unnatural, pinkish hue, officials claim the tinting doesn't do any damage to the surrounding ecosystems and that the effect clears up in just a couple of days.

## Dump It Elsewhere

To environmentalists like Lada, the industrial park's contributions to the economy are outweighed by its environmental footprint.

"Fish processing generates work... it's true," Lada told *AFP*. "But these are multi-million-dollar profit companies that don't want to pay freight to take the waste to a treatment plant that already exists in Puerto Madryn, 35 miles away, or build a plant closer."

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
