"Every story is a journey, and every journey is a story."

农业的可持续性不是一种选择，而是对后代子孙的必要责任。

The peculiar evil of silencing the expression of an opinion is that it is robbing the human race； posterity as well as the existing generation； those who dissent from the opinion， still more than those who hold it.

可持续发展不再是选择，而是生存的必需。
