Acid Rain

Acid rain is such a kind of rain which contains harmful chemicals. It is a widespread problem all over the world. It is the result of chemicals from burned fossil fuel mixing with moisture in the atmosphere and falling to the ground as rain, snow, sleet, etc. Human activities are mainly responsible for acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mixture of gases in the atmosphere. Besides, natural sources such as erupting volcanoes, rotting vegetation, and sea sprays produce sulfur dioxide and fires, bacterial decomposition and lightning generate nitrogen dioxide. The chemicals released by natural sources get mixed up with water and oxygen and get dispersed over large areas because of wind patterns and cause acid rain. Acid rain has been shown to have adverse impacts on forests, freshwaters, and soils, killing the insect and aquatic life-forms, causing the paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health. However, acid rain has harmful effects on the world environment and public health. Due to acid rain the PH level of waterfalls so much below that the conditions become hostile for the survival of aquatic life. It makes trees vulnerable to disease, extreme weather, and insects by, destroying their leaves, damaging the bark and arresting their growth. It also kills useful micro-organisms and leaches nutrients of the soil. Acid rain on buildings, especially those constructed with limestone, react with the minerals and corrode them away. This leaves the building weak and susceptible to decay. In fine acid rain causes a great effect on public health leading to injuries and deaths.
