Around a third of freshwater fish species are threatened with extinction. Through photography, South African biologist Jeremy Shelton hopes to inspire conservation of these ecosystems.
This is having an impact on both nature and humans. Freshwater fish provide food for 200 million people and livelihoods for 60 million, the report says -- and we depend on river ecosystems for water, sanitation and power.
"Rivers are the arteries of our planet," says South African freshwater conservation biologist and photographer Jeremy Shelton. "They transport cool clean water from the mountains down across landscapes and give us this critical resource that we rely on so heavily for drinking, for farming, for industry."

Federal Reserve Chair Jerome Powell has told multiple associates and allies that there’s no chance he will bow to President Donald Trump’s calls for him to resign, vowing to withstand several more months of the president’s unprecedented, multi-pronged assault over Powell’s refusal to lower interest rates.
