Acid rain is having harmful effects both on people and on the natural ecosystems of the world.  Scientists today are convinced that acid rain is severe in many areas, and that it is having an adverse effect on the environments of those locations.

The problem of acid rain is rapidly spreading.  Because it is mainly caused by industrial processes, automobiles, and power plants, those countries that are developed have the most severe acid rain problems.   However, as the undeveloped nations begin to industrialize, acid rain will increase greatly.

Determining just how much the planet is being hurt by acid rain is very difficult because the ecosystems that it affects are so diverse and complex.

Many ecosystems are affected by acid rain.  Bodies of water, such as lakes and rivers, see many of their inhabitants die off due to rising acidity levels.

Acidic water also ruins plant nutrients, hurting plants' ability to survive and to give life to other organisms.

Human-made products are also experiencing degradation from acid rain.  Cars can lose their finishes, and outdoor statues are beginning to rust.

Acid rain's effects are destructive and long lasting.  Though scientists have studied lakes, streams, and many other natural ecosystems to prove its negative effects, acid rain continues to be produced and is increasing in many parts of the world.
