I think this song is about the world as a whole.
People take the world for granted and just think, 'Oh, I made this little bit of mess, I'm sure a little bit of garbage won't hurt it. ' But the truth is, it does. And no one realizes it.
See the thing is, people start wars with little things. And this really damages the world and the world's natural beauty.
Also, it shows a lot in the video too. They are in Greenland, and they are stood on these mountains, in a space on their own. And in little clips of the video, it shows the mountains falling apart. And I know that this is cause by global warming.
This song is about caring for things and how when you look around, the world is beautiful, but in reality, it isn't, because people are destroying it.
