Do you like dolphins and turtles? If yes, please sign the petition to ban trawling in HK waters. Trawling is a destructive method of fishing that kills marine life including dolphins and turtles and depletes the fish stocks so that over time there will be fewer fish for next generations.
Not sure whether this is political or better in living in Hong Kong - so I put it here.
Here is the link to the organisation trying to get a petition together:
