Study Finds Human Noise Pollution Impacts 80% of Species Across Ecosystems
A recent study analyzing over 200 experiments on 177 aquatic and terrestrial species found that human-generated noise pollution affects about 80% of species studied, altering biological traits such as reproduction, immune function, and survival. Noise increases stress, impairs cognitive and reflex functions, and disrupts predator-prey dynamics, with predators expending more effort but catching less prey. Marine ecosystems are especially vulnerable due to sound propagation in water, impacting navigation and communication among species like whales. The findings highlight widespread ecological consequences of rising noise pollution.
