Questions about equal-cost conversion

China is one of the four ancient civilizations with a long history, early agricultural development, and high land utilization. It seems that China is very good, but in turn, we don't have much available land for development now! At the same time, due to years of poor management, many used land has gradually lost her past glory. We have to face this grim reality!

Using farmland for construction, well, invigorating the economy, and seeking for greater development -- it seems to be good at first glance, but think about it again-the RMB cannot be used as a meal ?! Naturally, some people want to supplement the farmland. This idea is even more beautiful, but we are bringing in the first paragraph. It seems that we are not so many supplements ??? -- My doubts are here!

Is there enough space to make up for the compensation balance? I found enough places, but these places may not necessarily produce the same amount of food as before? As much food is produced, transportation may not be as convenient as before ?...... There are a lot of problems. I can't try it for a while.
