噪音污染
Air and noise pollution are negative effects of vehicular transport. Air pollution negatively affects human health and the environment. Air pollution can cause acid rain, eutrophication, haze, wildlife deaths, thinning of Earth’s ozone layer, crop damage, and global climate change. Noise pollution disrupts ecosystems and wildlife. Active mobility reduces air and noise pollution by substituting for cars that produce greenhouse gases and noise, benefiting the environment and urban ecosystems.
