What a load of crap that either the Maori or other indigenous people own the land, water, sun, air, forests, birds, fish or beasts.
All the above was in place before mankind, either through evolution or creator. Otherwise mankind, regardless of race, could never have existed.
We co-habitthis universe with many species of birds, fish, animals, plants, insects etc, all dependent on the above to survive.
The only species on this planet to claim ownership of such is mankind, with his own mankind laws, for no other reason but to have wealth power and control, as the agenda of a few is either to buy or take from others for themselves, and God help anything that gets in their way.
If Maori or other races claim ownership of land, water, air, oceans, sun, forests, birds, fish etc then they must be responsible for erosion, flooding, storms, droughts, volcanoes, earthquakes, snow storms, fires, tsunamis, tornadoes, avalanches, sea level rise and much more.
I guess they would cover their backsides, like insurance companies, and claim it is an act of God, so if that is the case then they believe in a creator, so everything belongs to Him, end of story.
Ownership is a man-made law, for no other reason than wealth, power and control, just like profits from money that does not exist, but the interest paid is real money.
