Things that damage the economy indirectly.
For example I feel that fast food and an unhealthy lifestyle leads chronic health problems that probably affects the economy not just monetarily.
Of course we can't just deny these people care, just promote a healthier lifestyle.
What are other things that we can change that will affect the economy in a positive way?
Countries upgrade in technology. Permit me to use the recent event that occurred in Iran as an example, where a commercial plan was hit by a missile attack by the Iranian military. Which the military accepted as an act of mistake, and promised to upgrade their system to prevent future reoccurrence.
When countries refuse to upgrade in Technology due to selfish reasons, it can affect their economy negatively. And if they are open and accept new technologies, it will affect their economy positively.
