While the change will be very drastic in the scale of decades, climate change will not be perceived by most persons from year to year. The changes on a yearly basis will be small. Even now there is a large population that believes that climate change is a hoax. People will adapt to living in harsher conditions. People are self absorbed in their own lives, and don't plan for the long term of future generations, or even 20 to 30 years down the road.
Although there have been efforts, hardly anything has been done to curtail climate change in the long term. Greenhouse gases emitted continue to increase year after year.
Some say that humanity performs best when under pressure, that when things get worst, humanity will unify in their efforts. There is truth in this, but there is also truth in the boiling frog hypothesis. People will just get used to the way things are in the future, and would rather work hard at maintaining consumption, rather than trying to fix the root of the problem.
The biggest changes I see, come from socialist countries that are not allowed to follow the natural progression that the masses will follow. China has controlled its population with its one child policy. China is also setting up “forest cities”, where the city landscape is dense in vegetation: https://news.culturacolectiva.com/mundo/china-crea-la-primera-ciudad-forestal-del-mundo. I prefer democracy, but I must give credit where credit is due. Some say the one child policy was cruel, but the long term consequences of overpopulation would have been worse.
Marcos: Do you think people should have to reuse their own containers, pouring or scooping out from bulk in the supermarket? Granted, some things are hermetically sealed to increase shelf life, but one could trade-in a similar container for one on the shelf? There are glass bottles for milk at the supermarket that have a $2 deposit.
Liz: The supermarket I use allows you to take your own container for meat and fish, and I am a fan of refilling things. It needs to be dealt with more at the supply level, as consumers may forget their container, but if things are packed in such a way to reduce their impact then the consumer doesn't have a say.
Marcos: There should be a container-tax, of sorts. Paying a dollar per plastic container would add up. The proceeds could go into environmental sustainability.
