I think it's a combination of both technology and changes to our behavior. A cheap way to sequester CO2 and methane would be really helpful. The 2020 lockdowns showed us that slowing down on shipping and driving to work can make a measurable positive impact on our environment. But we'd have to get over our own ego and greed to do this full time.
2020 showed that we can have remote work as the primary method of work for a vast majority of jobs. The government could’ve mandated that if your company’s work could be done remotely, remote work has to be an option.
The amount of emissions to support daily commute of this many people (especially with commutes getting longer and longer) is insane.
