Fish and vegetables from Berlin, Germany.
There, basil is grown in the same water as the water in the aquarium where the fish are grown.
Basil converts the carbon dioxide produced by fish into oxygen.
Since the production area and the consumption area are the same, the transportation cost can be reduced.
Some say that there is an epoch-making attempt to produce fish and vegetables in supermarkets and reduce the transportation distance to zero.
At first glance, this is a wonderful initiative, but we must not forget that the excessive evolution of civilization has damaged the earth.
I pray that we are humble human beings on the earth.
