Global Ecological Balance (The human settlement that we need)
We are in the middle of a major ecological crisis on a global scale. We have no practical experience on how to face it, since it is the first time such a dangerous type of crisis has occurred on a global scale, at least in historical times. To face it humanity, since 1869, has started the science of ecology by using natural history approaches which go back to Aristotle's natural history. Now there are many studies, some of which are of very high quality, which begin to open our eyes to what really happens and what has to be done.
