We humans have lived on Earth for about 200,000 years. But it was only about 100 years ago that we began to spend most of our time in cities and indoor spaces. If we consider this to be a 24-hour day, we have only been inside for 6 seconds. Today we spend 90% of our time inside and only 10% outside. Therefore, we have set ourselves the goal of bringing back a piece of nature to people in everyday life.
