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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The cleaning was common back then. Every store took back the tall glass bottles of soda and in modern times oberweiss brought that back with milk. The glass melting is nice just as a final option really.

That's reuse, not recycling. Glass is much more suitable for reuse than plastics as it's longer-lasting and can withstand temperatures hot enough and cleaning agents strong enough to ensure it's food-safe after being collected, but you need quite a bit of infrastructure to get the bottles back to the company whose products they're for. At least for the parts of a bottle's life that the manufacturer's responsible for, it can be much cheaper to make fresh plastic, and if they can externalise the environmental cost of disposing of a plastic bottle (i.e. blame the consumer), it can look better for their carbon footprint etc., too.

yeah I was not limiting my comment to recycling just about how we don't really need to be using plastic everywhere and how things were pretty fine in the 70's where you only saw plastic in a few use cases.
