yeah, I really prefer cleaning natural place than city, but the result is quite the same in the final ^^

Yeah, I'm stuck in the city, but a lot of trash here ends up in the gutter, which washes down to the sewer, which empties into the rivers - without going through a water purification system, the street drains are separate. So I'm just stopping it from washing downstream! :)

That's absolutely true ! And it's already a very good thing ! it's good to act at every levels and advancement of the pollution !!
