One Third of Freshwater Fish Face Extinction, New Report Warns
"Nowhere is the world's nature crisis more acute than in our rivers, lakes and wetlands, and the clearest indicator of the damage we are doing is the rapid decline in freshwater fish populations. They are the aquatic version of the canary in the coal mine, and we must heed the warning," Stuart Orr, WWF global freshwater lead, said in a statement Tuesday announcing the report.
WWF is one of the many organizations behind the report, along with the Alliance for Freshwater Life, Conservation International and The Nature Conservancy, to name a few. Together, the groups emphasized the incredible diversity of the world's freshwater fish and their importance for human wellbeing.
There are a total of 18,075 freshwater fish species in the world, accounting for 51 percent of all fish species and 25 percent of all vertebrates. They are an important food source for 200 million people and provide work for 60 million. But their numbers are in decline. The IUCN Red List of Threatened Species has declared 80 to be extinct, 16 of those in 2020 alone. The numbers of migratory freshwater fish such as salmon have declined 76 percent since 1970, while mega-fish such as beluga sturgeon have fallen by 94 percent in the same time period. In fact, freshwater biodiversity is plummeting at twice the rate of biodiversity in the oceans and forests.
Despite this, freshwater fish get much less attention than their saltwater counterparts, the report authors say. Titled "The World's Forgotten Fishes," it argues that policy makers rarely consider river wildlife when making decisions.
The main threats to freshwater fish include building dams, syphoning river water for irrigation, releasing wastewater and draining wetlands. Other factors include overfishing, introducing invasive species and the climate crisis.
"As we look to adapt to climate change and we start to think about all the discussions that governments are going to have on biodiversity, it's really a time for us to shine a light back on freshwater," Orr told NBC News.
To protect these forgotten fishes, the report authors outlined a six-point plan:
1. Let rivers flow more naturally;
2. Improve water quality in freshwater ecosystems;
3. Protect and restore critical habitats;
4. End overfishing and unsustainable sand mining in rivers and lakes;
5. Prevent and control invasions by non-native species; and
6. Protect free-flowing rivers and remove obsolete dams.
They also called on world leaders to include freshwater ecosystems in an ambitious biodiversity agreement at the upcoming UN Convention on Biological Diversity conference in Kunming, China.
But the solution will require more than just government action.
"It's now more urgent than ever that we find the collective political will and effective collaboration with private sector, governments, NGOs and communities, to implement nature-based solutions that protect freshwater species, while also ensuring human needs are met," Carmen Revenga of The Nature Conservancy told BBC News.
To save the planet, we must save the Amazon rainforest. To save the rainforest, we must save its indigenous peoples. And to do that, we must demarcate their land.

"Today's interim report from the UNFCCC is a red alert for our planet," said UN Secretary General Antonio Guterres.
The report, released Friday, looks at the national climate efforts of 75 states that have already submitted their updated "nationally determined contributions," or NDCs. The countries included in the report are responsible for about 30% of the world's global greenhouse gas emissions.

India's New Delhi has been called the "world air pollution capital" for its high concentrations of particulate matter that make it harder for its residents to breathe and see. But one thing has puzzled scientists, according to The Guardian. Why does New Delhi see more blinding smogs than other polluted Asian cities, such as Beijing?

In a historic move, the Delaware River Basin Commission (DRBC) voted Thursday to ban hydraulic fracking in the region. The ban was supported by all four basin states — New Jersey, Delaware, Pennsylvania and New York — putting a permanent end to hydraulic fracking for natural gas along the 13,539-square-mile basin, The Philadelphia Inquirer reported.

Colombia is one of the world's largest producers of coffee, and yet also one of the most economically disadvantaged. According to research by the national statistic center DANE, 35% of the population in Columbia lives in monetary poverty, compared to an estimated 11% in the U.S., according to census data. This has led to a housing insecurity issue throughout the country, one which construction company Woodpecker is working hard to solve.
