These are kind of false comparisons. It's comparing man-years spent watching Gangnam Style against years spent building the Taj Mahal. There's a huge difference. Divide the number of years given by the population of planet Earth to get the number of years the entirety of humanity wasted on Gangnam Style (it's something like 0.00000207 years - off by 11 orders of magnitude). Or multiply the number of people who built the Taj Mahal by the number of years they spent building it to get the number of man-years they spent. I'd guess around 1,000 people built the Taj Mahal. That's 21,000 man-years, even more than was spent watching Gangnam Style.

Of course, if you added all the numbers for all the stupid youtube videos, memes, worthless news articles, facebook posts, etc. together, then you'd probably get something terribly depressing. My guess is some tiny fraction of humanity actually sustains the rest of the species. They are the (much less than) 1%.
