I have removed all branding from my site that contains nature. This means my logos, which are panda-based, and other images have been altered to remove nature so we can see what a world without nature looks like. These changes will persist from approximately midnight on the morning of 3 March in Kiritimati (Christmas Island, UTC+14) to midnight on the night of 3 March in Alofi (UTC-11).
I might not be a company, but I do have nature in my branding: bamboo and a panda – which I share with the WWF, who are the reason I can’t have panda.org as a short URL! I think it makes sense that I remove these elements from my branding on this day.
