To get the right to a plot you would pay relative tax and scout out a legal plot with your phone near where you live and pay the tax for it. if you pick the right plot it can cost less than an allotment today and works better with nature than owning more and more of a chunk of nature. Why not own more better stuff from a near endless green supply of the same stuff recycled instead of owning land and get greedy on wanting to find good fits where to do good and improve on natural wealth.
If you do work with real estate why not do you business with a strong ethical and ecological twist and profit at the same time.
Getting more money should be only one aspect of being the next millionaire or billionaire.
being ethical and ecological can have a style all of your own to it.
