Pressures on air quality

Māori and the air

To Māori, air is a taonga or treasure. The Waikato region generally has good air quality, but some areas experience air pollution. Māori are concerned about effects of pollutants on health, the environment and the spiritual values of other taonga.

Climate change

The Waikato region is already experiencing the effects of our changing climate. The changes present risks to our economy, our people, our property and our environment.

Ozone depletion

Some human activities release chemicals into the air that remove ozone. Less ozone in the atmosphere increases the amount of ultra-violet rays that reach the earth.

Weather and air quality

What the weather is doing can have direct effects on air quality at a given location.
