A new citizen science programme called Upstream Battle has been launched by Keep New Zealand Beautiful.
The programme aims to identify the most common on-land sources and types of litter, using schools, community groups and individual volunteers to gather data that, in turn, will inform action to stop litter entering streams, rivers, lakes and oceans.
An estimated 80 per cent of all marine litter globally starts its journey on land.
Volunteers will be given training and provided with a resource pack. To learn how to join the campaign, visit: www.knzb.org.nz/programmes/citizen-science/upstream-battle
