Our responsibility

Reduce first: what you don’t use needn’t be recycled.

Many people’s small choices add up. The environment also belongs to the next generation: it is a duty, not just a choice.
Air pollution from factories and traffic worsens asthma and other lung problems.
A polluted river: report it and organise a clean-up. Indigenous plants need less water and feed local wildlife.

Remember this and test yourself

Remember this: your summary

Climate change: a long-term shift in the climate; for SA it means more extreme droughts and floods.
Most greenhouse gases come from burning coal, petrol and diesel.
Carbon footprint: the greenhouse gases your lifestyle causes. Walk, share lifts and save electricity.
Renewable (solar) replenishes itself; non-renewable (coal, oil) runs out.
Environmental justice: everyone has the right to a clean, safe environment; poor communities near factories suffer most.

Write these points in your book. Read them again the night before the test.

Memory trick

A carbon footprint is like footprints in wet cement: the heavier you step (more fuel and power), the deeper the print.
