There seems to be a growing hunger for cutting out plastic. We need to stop it at source. With plastic in the zooplankton at the very bottom of the ocean food chain, how long will it be before plastic fills every gut of every marine animal there is, and then long outlasts the corpse... and goes on to fill more fish, birds and sea animals (and ourselves, who eat them!).
In terms of how - I think we can boil down our responses to 5 things:
1 - Feed the right wolf (buy the biodegradable material rather than the plastic item) in our own shopping;
2 - Live simply (negating the need for that purchase in the first place);
3 - Advocate for change (through change.org, uplift.ie, sumofus.org, avaaz etc., through letter and email campaigns, through communicating with manufacturers, local and national governments etc., Extinction Rebellion etc.);
4 - Hold hands (find like minded company for support and assistance and company while you engage with the other elements);
5 - Hold the vision (what top athlete will tell you that she succeeded in getting that Olympic gold by picturing a good clear image of a terrible outcome? None. Similarly, even as we face into uncertain times, we may do well to hold a very clear positive image of a desirable goal: even something as simple as feeling really good that our local health food shop now stocks wash-up loofahs, to take just one example)
That's all ;-)
