Increasingly, more and more land is made into buildings, I do not deny it, it is a fact that occurs due to the factor of increasing human population every year, vertical agriculture is certainly a solution to deal with this problem, but yes it will certainly take up a lot of waste from this agricultural practice As it is today, which on average requires plastic tools in its implementation to make it easier and cheaper, but I don't mind that.
There’s still a lot of lands available on other country while highly urbanized country can always import agricultural goods from other country that focus on this as main source of product. Vertical is indeed very popular on highly urbanized area but most of them is just using the goods for their own consumption and not for market distribution.
Maybe in the future this will become popular and a must but right now there’s still a lot of country especially 3rd world country that farming crops for export purposes. Rich country can pay for the export fees since they are getting huge income from taxes of people job on highly urbanized areas. It’s a give and take.
If it includes a broader, it is certainly not good if you meet the needs of your country by only holding on to other countries, utamanaya the third state, it is a narrow thought in my opinion, because if you are too dependent on other countries in this case, your country will is under the influence of other countries and it is not good for the sovereignty of the state because it can be disturbed, over time the exact price of organic food commodities will increase because the narrower production land and demand more, the owner of the goods will ask for more payment, and your country will be very beaten if a significant price increase is implemented.
Like European Union that relies on nickel from Indonesia, then Indonesia is louder to manage it itself, and carry out an export stop policy that makes nickel prices rise, and the European Union can only report and report to the WTO.
