There are some people in my country who throw garbage to the river and when rainy season comes, water that cannot flow smoothly eventually causes flooding and indirectly inhibits economic activity in that area.
Simply go to researchgate.com and you would find millions of factors that correlate with your economy. I think that wasting time is also a factor that brings down the economy. Look at Japan. The country has progresses at an accelerated pace in the last 40 years just because even kids are involved in economic activities let alone the grown-ups and the businessmen.
