Bob Hughes cannot be allowed to blame colonisation and Pakeha farming methods for all of the deforestation and damage to Aotearoa.
“When Māori arrived, about 1250-1300 CE, they burned large tracts of forest, mainly on the coasts and eastern sides of the two main islands. By the time European settlement began, around 1840, some 6.7 million hectares of forest had been destroyed and replaced by short grassland, shrub land and fern land.” — https://teara.govt.nz/en/interactive/11674/deforestation-of-new-zealand
ALL of the people who have lived in Aotearoa are responsible for where we are today — not just any particular group.
I might also point out that Māori were enthusiastic adopters of European farming, new animals and crops — and quickly became sharp traders in their own right and adopters of the money system.
We are in the sad environmental situation of today because all of us — collectively — have ignored all of the many warning signs that our way of living is contrary to nature, and despoiling the planet.
