Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Shock horror. The famously corrupt industry that gets paid both to take waste and to sell their byproducts is corropt and doesn't deal honestly.
Also, FYI biodegradable plastic is a con. Plastic is polyethylene, which is a long chain of repeating ethylene molecules. To make it biodegradable they just put starch molecules in the chain every so often. Bacteria break down the starch leaving tiny microscopic ethylene chains you can't see - aka microplastics. Biodegradable plastics are in fact more polluting.
A lot of plastic is polyethylene, but nowhere near all of it. There are plenty of polymers that can break down naturally, mostly polyesters like PLA (which breaks down into lactic acid, the same naturally produced compound that causes muscle soreness after workouts). A lot of work is being put into making PLA have better material properties so it can replace more of the conventional plastics. It's also generally made from corn and can be pretty close to carbon-neutral. So long story short some biodegradable plastics are worse, but some have legitimate applications and are genuinely better than current options.
