Healthy Planet offers a clear and concise overview of the global ecological crisis that humanity has brought upon itself, and what options we still have to save a benevolent climate, to restore biodiversity, reduce pollution, and heal the ecosphere of this planet, including ourselves. Since well before the Covid-19 crisis the United Nations have been emphasizing that only a healthy planet can support healthy people. The degradation and pollution of nature also poisons our own bodies. Climate breakdown and the global loss of biodiversity also threaten the human species. But what is a "healthy planet"? How does it work, how much do we disrupt the planet’s life support systems, and what changes are overdue? We have all the necessary means at our disposal, though just patching up the worst symptoms won’t do anymore, we have to address the underlying causes, including our habits, values, and paradigms. We are at a crucial crossroads, and time is running short. If we act fast enough, a dignified and truly sustainable healthy future awaits.
