Climate change denial I understand where you're coming from, yet I fail to see how I could improve such a situation in any meaningful way. — Arcane Sandwich
One way you could improve the situation is by developing a better understanding of the issues. Plastic pollution is a serious environmental problem, but it is not a major contributor to anthropogenic climate change. The Earth is warming because of the insulating effect of changes in the atmosphere, mainly the increase of carbon dioxide from the burning of fossil fuels and the increase of methane from various sources, farmed cattle emissions, natural gas leakage, permafrost melting, etc. Plastics actually function to lock up carbon long term and so function in a minor way as a carbon sink. But do not take that as a vote in their favour.
So the issue for this thread at least, is the
burning of fossil fuels rather than their transformation into plastics, unless those plastics are incinerated. Petrol, diesel, aviation fuel, coal, natural gas, are all hydrocarbons whose combustion add to the insulation that warms the earth.
Pollution has some importance too, because it degrades the ability of the living environment to absorb carbon dioxide, and rebalance the atmosphere. But the major impact comes from oil and coal burning, and that is what needs to stop.
Of course things get much more complicated as one goes into the details, and we can talk about positive feedback and tipping points and sun-cycles and Milankovitch cycles, and bees, and krill, and plastics, and so on and on. But please understand, our total addiction to fossil fuels is the big problem and if we don't sort it, the world will heat up until we either do sort it or the heat sorts us.
