As someone who spends 10+hr a day working outside I can assure you that being outside and doing physical activity does very little to aid my depression.
if you talk with some of the workers, they will often toss out the popcorn at the end of the nigh. Ive been know to take in a trash bag and fill it up.
It's only going to get worse in the coming years as weather gets more extreme and entire towns and city's get swallowed up by the ocean.
