April 22nd is 'Earth Day', a modern environmental movement that started in the 1970s. Since then, environmentalists have been trying to engage people in dialogue and action to preserve the planet we live in. But seeing the rate we're failing to do that, thanks to the ever increasing human population, over-consumption, hunger for non-renewable resources, etc., we can safely say that soon, Earth Day will be obsolete. Because there won't be any humans to remember it.
That is the legacy we, as a generation, will leave for our children. And this video nails it, while delivering an apology that might just be too little too late.
