This book is about the possibility of realising a sustainable relationship between humans and the rest of nature, partly by creating a sustainable planetary culture of peace in which it is a matter of course that ecosystems, too, have rights, and partly by developing our legal systems so that, in effect, it becomes illegal to destroy ecosystems. The question of how to make peace with nature seems to be present as an unspoken longing in many of the efforts, on every level and in every sector, to reach the goals of a sustainable society. Peace and rights are interconnected, and the conversation about the rights of nature is attracting more and more attention. This makes it important to examine these ideas more closely.
