So oat milk is better for the environment?

Jacinda is our prime minister. Her role, among other things, is to foster a beneficial social and business climate that is conducive to our country's businesses but not to invest in their operations. You seem to be confusing our country's governing with that of a totalitarian communist state.

If this govt really cared about climate change, they would have it in their interests to reduce imports.
We need to be self-reliant and produce all the goods we need here ourselves.
When it comes to food production, thats even more important, we loose our farms, then who will supply us the food?

Two holes in that last assumption. We currently produce sufficient food to feed ~40 million people, so 8 times our own requirements, so reducing the production of a few farms isn't going to impact our ability to survive, and those 'lost farms' aren't going anywhere, they will just change their land usage.
