Задание 39 ЕГЭ по английскому языку

Although most noise pollution is man-made, natural events can produce a lot of noise and increase noise pollution, too. During a thunderstorm, lightning and thunder produce loud, sudden noises that can frighten people and cause much stress, especially during nighttime. Volcanic activities produce loud noises as well, which affects both local people and wildlife. Earthquakes, even small ones, make noises, too. Some natural weather conditions like heavy rain, strong winds, and flowing rivers generate constant noise that can also affect both humans and animals in many ways. Apart from these natural events, there is biological noise. It refers to sounds produced by living beings. While often minor ones, certain noises can contribute to overall noise pollution in some cases. Sounds from wildlife, such as bird songs or insect noises can add to noise levels in nature reserves and parks.
