experienced (thankfully) throughout my adolescence. In an attempt to combat teenage loitering, numerous businesses and storefronts throughout the U.K have placed a sound box outside, known as 'The Mosquito'.

Biologicals are one type of natural noise in the marine environment. Biologicals refer to when marine animals use their underwater acoustics to communicate with each other, explore their surroundings, or to find prey.

Is that even English? “9 times out of 10, most of the noises you hear can be quite annoying to others.” Ninety percent of the noises everyone hears are annoying to other people? Does everyone…

In addition, the water and soil pollution can also affect our health in various ways. According to the…
