Human Activities Accelerate Decomposition in Rivers, Elevating Carbon Emissions

New study reveals how urbanization and agriculture disrupt natural processes, threatening biodiversity and climate stability.

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.
