I'm asking a general question, everybody is affected in some way or another, and no country is spared.

For instance see the multiple articles recently posted to HN about how microplastics are present even in the air we breathe, or in water in very remote, 'unspoiled' locations.

Edit : I'm interested in what others do, specific actions, like buying organic produce, avoiding tuna, filtering water, etc.

What things they do, how often, why, etc.
