Why we drink rainwater?

We should not drink rainwater. Rainwater is not safe to consume because it can be contaminated with a variety of pollutants, including bacteria, viruses, and heavy metals. Raindrops can pick up pollutants from the atmosphere, including nitrogen oxides, sulfur dioxide, and hydrocarbons, which can form acids when they dissolve in water. Rainwater can also pick up pollutants from surfaces it flows over, such as roofs, gutters, and soil, which can contain bacteria, viruses, and heavy metals. Drinking rainwater can pose a serious health risk, and should be avoided.
