Just googled for "earth flag". Among the various results, this is the only one that impressed me: http://marketblog.envato.com/wp-content/uploads/2015/05/ru75u9.jpg.png http://marketblog.envato.com/wp-content/uploads/2015/05/ru75... Not saying it could actually be used as a flag. Notice how it puts the accent on us rather than the environment. I find it fresh and combative, it reminds us of our unity but also of our animality. It says very well who and what we are (without giving away our address!). However it's not inclusive and well-meaning enough to be politically acceptable. Isn't that strange? All the other efforts, including the one linked by the OP, look trivial or perfunctory to me.
