I just had a great ideaWatch
So... all people who are out of work should be paid to run in giant hamster wheels all day in order to make electricity. That simple sentence would solve the energy crisis, global warming, unemployment and obesity all in one.
If you think a few thousand men running in hamster wheels can solve all of the things you stated. Lol
I also have other ideas relating to solving the housing crisis and the migrant crisis but one thing at a time.
