The Waitematā Harbour is an intertidal ecosystem inhabited by clams, cockles, crabs, algae, and microscopic worms.
In a recent University of Auckland study on the effects of microplastics in the Waitematā Harbor PhD Candidate Sam Ladewig found that plastic pollution is fundamentally altering the natural cycles of life in the harbour's waters.
The investigation found that microplastic pollution is altering the flow of oxygen through the systems, and the long-term effects of this are currently unknown.
This week on The Green Desk, Troy spoke to Ladewig about the study and the harms of plastic pollution on New Zealand’s oceans.
Sometimes you can't see the forest from the trees but spare a thought for the wilderness beneath the waves. Kelp forests are found in shallow ocean waters off a third of the world's coastlines, and, according to new research are worth hundreds of billions of dollars to society.
Marine ecologist Dr Aaron Eger led the study and is also the founder and director of the Kelp Forest Alliance – a research-driven not-for-profit dedicated to accelerating the protection and restoration of kelp forests worldwide. Today he's on The Green Desk to discuss his work putting a dollar value to the kelp forests below the sea level.
This week on The Green Desk things get shitty — New Zealand has a poo problem: An estimated 100 million tonnes of cow and sheep manure fall onto New Zealand pastures each year, causing an environmental and economic stink.

Bronwyn speaks to Kevin Moran from Save Our Springs about Te Waikoropupū Springs which are currently the subject of a Water Conservation Order being challenged in the Environment Court.
Located close to Takaka in Golden Bay, these freshwater springs are the largest in New Zealand and contain some of the clearest water found in the world. The iconic blue-tinted waters are recognised as a wāhi tapu by the Māori Heritage Council and are of great cultural and spiritual significance to local iwi Ngāti Tama, Te Ātiawa and Ngāti Rarua.
In 2017, Ngāti Tama and Andrew Yuill applied for a Water Conservation Order, however the special tribunal's recommendatory report was not published until the 17th of March this year. In response, ten parties have lodged further proceedings in the Environment Court, some believing the tribunal's report was too strict and others, not restrictive enough.
Save Our Springs is among those appearing in court later this year, calling for improvements to the draft order.
