Lesson content

When Air Becomes Harmful

Clean air is needed for breathing, but air may carry smoke, dust, soot, harmful gases, very small particles, pollen or disease-causing germs. Smoke and fumes can irritate the eyes, nose and lungs. Dust or pollen may trigger coughing or breathing difficulty in some people. Respiratory infections spread mainly when an infected person releases droplets or tiny particles while breathing, talking, coughing or sneezing; pollution does not itself create viruses.

Harm to People and the Environment

Smoke from fires, vehicles and poorly vented cooking places can make breathing difficult.
Strong winds may remove topsoil, damage roofs or break branches.
Dust storms reduce visibility and can worsen breathing problems.
Air pollution can damage plants and make places uncomfortable to live in.

Simple Protection

Avoid smoke and unknown fumes, keep rooms ventilated when it is safe, cover the nose and mouth when an adult advises it, and report breathing difficulty immediately. Children should never burn refuse or mix chemicals.
