Full Answer

Emissions from buses, trucks, trains and factories introduce nonbiodegradable toxins into the atmosphere, which cause harm to humans and the environment. Planes, trains, buses, cars and factories produce noxious fumes and smoke that contain mostly synthetic compounds. The byproducts produced in these emissions do not dissolve when exposed to air particles. Instead, they may linger in the atmosphere for decades or longer and disrupt critical environmental functions, such as the proper filtering of UV rays, in the process. Water pollution, which comes in the form of industrial waste products added to rivers, lakes and streams, may poison organisms in aquatic habitats and result in less biodiversity. Soil pollution that is caused by runoff containing pesticides, fertilizers and other chemicals may spoil crops, stunt the growth of plants and native vegetation and harm microorganisms that live in dirt. Lastly, light and noise pollution may cause hearing damage and confuse migratory animals such as birds.
