Pollution comes in many forms. Pollution from industry can put unwanted
chemicals into the air, damaging the environment. When people or animals
breathe this poor quality air it can make them sick.
Pollution can also be garbage that people throw on the ground or into
the ocean, lakes or rivers. In addition to making the earth look ugly,
this pollution can make animals sick or even kill them.
Chemicals and other materials that aren't good for the environment
must be properly disposed of to prevent pollution. Not littering and
recycling can help reduce pollution and make the environment more beautiful
and safer for people and animals.
