Look, apart from cyber garden game thing, I come up with another awesome activity to solve food security problem.
We can add a small department to our community called Local Food Bonus. Basically, if you buy local food for one week in row, you will get a chance to grow a tea tree for free.
You know, in China, we have a large population. So you seldom see farmland in big cities. However people live in big cities are eager to do some farm work in weekend just for entertainment.
My idea can hit two birds with one stone. Bingo!!!
