Today we globally celebrate Earth Day. What better occasion to read and share the Letter to Humanity written for all of us by NNN director Koert van Mensvoort? Humanity is at a crossroads, there are two paths along which our relationship with technology can develop: a dream or a nightmare. That's why the Letter to Humanity urges us, humans, not to be slaves or victims of our own technology, but rather to use it to enhance our life on this planet. US Senator Gaylord Nelson initially introduced Earth Day day in 1970 to protest an oil spill in California. Today it is about the relationship between man, nature and technology, as technology is becoming a nature of its own. Until date, Earth Day is among the most widely celebrated eco-events across the world. Acknowledged in 192 countries, today it focuses on creating awareness about our planet and demonstrating support for environmental protection. It's a day to celebrate our planet, that despite all the differences between people, we still share. For NNN this day is the opportunity to spread the Letter to Humanity. Because after all, humanity is all of us. Read, share and inspire via #lettertohumanity or visit lettertohumanity.org. If you'd like to do more, you can also copy, translate and further distribute the letter, or write your personal one!
