30 Various Hobbies That People Invested Hours And Hours In And Which They Now Regret, As Shared Online

Do you know what exactly some urbanists saw as almost the main environmental problem of big cities at the end of the 19th century? I'm willing to bet you're unlikely to guess! So, scientists seriously believed that in the future, that is, for example, at the beginning of the 21st century, humanity would have to urgently solve the problem of recycling... horse manure!

And it's true, these scientists argued - if the population of the Earth grew, then the number of horse-drawn carriages and cabs would increase - and numerous horses, of course, would pollute the city streets with manure. An example that clearly shows how far even the smartest of us can be from accurately predicting the future. So don't laugh too hard at the stories in this list of ours, which collects people's skills and hobbies that later turned out to be not even worth the time spent mastering them.
