The idea of land/house ownership is at fault with any viable, conceivable solution for a sustainable future of the planet.
While the Earth's human population is growing ever more rapidly, the area of available habitable land is shrinking, giving the field to the acquisitions for the industry, urbanisation and exclusive private ownership.
Nobody should claim a permanent right to any land or water mass in the same way as nobody should own the air, the skies or the sun.
Making the land a common good and value would bring greater care and appreciation for it. Ownership and use of land should never be a permanent right, in the way human lives are not to last forever.
Private ownership of the land leads inevitably to the abuse and lack of concern for the latter.
Responsible cohabitation needs to be perceived as natural, ethical, modern and fashionable.
I guess that propagation of the above idea should start at the earliest stage of any social education, with the help of leading influencers and intellectuals.
