I think many people share their passion for nature. I know many people who have their wallpaper as a photo of nature, or who just has a lot of pictures of nature in their gallery etc. I know, this is not an indicator of how many people love nature, but it shows that when many people have the choice of random photo (cars, cities, musical instruments, people etc) they choose a photo of nature. And that just goes to show. Hope this helps, feel free to message if you have any other questions
