Acid Rain

by Brandon

All rainwater has some acidity. Acidity is measured by pH. The pH scale measures the amount of acid. PH is measured on a scale from 0-14, with 7 being neutral.

The lower the number is on the pH scale, the more acidic a substance is. Normal rainwater has a pH of 5.6. When the pH level of rainwater goes below 5.6, it is called acid rain.

We are contributing to acid rain whenever we turn up the furnace thermostat to keep warm in the winter. By burning oil, we are polluting the environment.

We can also cause acid rain by driving cars, trucks or motorcycles. We are polluting the air without thinking about the harm we are doing to the environment.

Acid rain is very harmful. Acid rain damages everything over a period of time because it makes the living things in the environment die.

Trees are dying because acid rain is harming them. Acid rain damages the outer coating that protects the leaves. When this happens, the acid seeps into the trees and eventually kills them.

Acid rain threatens our health by making us become sick. Breathing and lung problems in children and adults who have asthma have been linked to acid air pollution.

Lakes and streams are normally slightly acidic. Heavy rainstorms or melting snow can cause the acidity in lakes and in streams to increase.

All sea life will die when the water they swim in gets to be too acidic. For example, all fish will die when the water goes below a pH of 4.5.
