New Zealand, like other countries, is exposed to a range of substances that can damage our health and the health of our environment.
These substances are:
- hazardous substances
- new organisms and other biological technologies
- ozone-depleting substances such as methane.
The types of damage that can be caused include:
- contamination of land, rivers, lakes and the marine environment from hazardous substances used in industrial processes
- damage to the health of native fauna and flora from new organisms
- damage to the ozone layer from ozone-depleting substances.
When well-managed, these substances and biological technologies help us achieve important economic goals and improve our well-being.
- new organisms are used to enhance crops and develop medicines
- hazardous substances (eg, pesticides) are used to protect our native species and crops from harm.
