When it comes to sustainability, we seem to have dug ourselves a hole which, if we carry on, will bit us in the backside hard eventually. Human history has shown that societies that lived unsustainably ultimately perished or at least suffered badly.
We are told that we need more working people because health care for elderly people (especially those with ongoing health conditions) and pensions is expensive, and the ratio of retired people to working people is increasing, generating an increasing tax burden on those working people. There is an upper limit to how much tax revenue the government can squeeze out of people (because wages are finite and a basic income required to live is greater than zero). The standard solution is to either increase the birth rate, which in a couple of decades leads to more young people entering the job market, or have people move here from abroad for work, who then contribute to tax revenue. The problem with this is those working people eventually become retired people, and you then need even more people in the workplace to generate tax revenue to support those retired people. What you end up with if you want to keep balancing social care with tax revenue is an increasing population. An increasing population is not sustainable because land space does not increase over time, so there is an upper limit to how high the population can get before undesirable things start happening (like, for example, massive house price inflation due to demand exceeding supply).
The current mantra of continunal economic growth is ultimately "wrong" because it is unsustainable as a result of resources being finite. The solution is a steady state economy, but that is an anathema to capitalism, so you need to ditch capitalism and create a completely new way of living that is compatible with resource consumption being balanced by resource creation. Good luck with that.
To be honest I wouldn't mind doing that if anyone was interested, alternatively I would like to talk to some of those who have been panic buying to try and understand their thinking, and I would be happy to explain why I don't panic buy.
