Generations of New Zealanders have lived by the 'Go big or go home' attitude.
In 1908 the government passed an Act that authorised large-scale drainage of wetlands. That was followed by the provision of government incentives to make sure any soggy land was cleared and 'put to better use.'
In later decades, successive governments encouraged the felling of native forests to make way for further sheep and beef farming, which, let's be fair, did hugely help with our bounce back from both world wars, and provided lavish subsidies to boost livestock numbers and to keep fertiliser cheap.
What the government and markets encourage one day may be something that very soon we're all pouring resources into trying to find solutions to fix.
After the '80s, the sudden removal of subsidies forced farmers to be more productive and efficient, and encouraged them to chase the highest-value land use. Dairy turned from being farming's poor cousin to a boom industry. Mass conversions followed, with dairy literally providing the butter to our bread.
