OK, but...that entire tank contains less CO² than the average car emits every kilometre. I don't think soda stream are contributing massively to global warming. The fact that it's an Israeli company with a history of exploitation of Palestinian labor, complicity in settlement expansion, and continued violations of Palestinian human rights, is a very good reason not to use it.
Edit. Oops, worked that out from the assumption of 60L of CO², closer inspection shows 410g, which would be around 3.5 KM.
Edit 2. The average person breaths out more than twice this amount of CO² a day. Perhaps being complicit in genocide is Soda Stream being carbon neutral?
What if we collect the CO2 from cars and fill up the cartridges with it and then we drink the car CO2 water? We can drive cars and combat climate change!
I think the loss of human lives at a large scale will eventually bring a new earth cycle to normality. It may not be the same ecosystem that it was, but it might be stable with humans being less of an infestation. This may be virus or starvation. We'll all see soon enough.
