Overview

• Researchers found that human impacts are speeding up the decomposition of organic matter in rivers and streams globally.
• Accelerated decomposition releases more carbon dioxide and methane into the atmosphere, contributing to climate change.
• The study involved data from 550 rivers worldwide, highlighting the role of temperature and nutrient pollution.
• Increased decomposition rates can disrupt local food chains, affecting insects and fish that rely on organic matter.
• Reducing human impacts on waterways could help mitigate climate change and improve water quality.
