Playful Sea Lion Pup Plants Huge Kiss On Snorkeler (Video)

In 2003, the great pop band Busted wrote a song about their neighbour, called Peter, who’d built a time machine with a flux capacitor. True story. In the song, Peter documented his recent excursions to different eras along the space/time continuum. He said ‘I’ve been to the year 3000, not much has changed but they live underwater’.

Now if you ask me, if the entire human race lives underwater in less than a thousand years from now, that's a pretty major change, Peter. I'd love to know what else you've seen on your travels which makes humans going from above-ground creatures, to living underwater, seem like not that big of a deal. That lyric has stayed with me for years. There's so much to it. Not least, for example, the question, if we did live underwater, would we still have regular pets like cats and dogs, or would various sea creatures be the new household pet?
