Let’s be realistic. Inspiring a mind-shift to sustainability could take a generation, and we should have started long ago. If we wait 30 more years, it will be too late. So we advocate a two-track approach: 1) tackle the most urgent problems right now, such as climate change, nitrogen and phosphorus overload, and loss of biodiversity, but also 2) do everything we can to reconnect with nature over the long term. Earth deserves nothing less. Our world depends on nothing less.
