Please, just
quantify.
we all have different morals
No we do not, all non irrational humans are utilitarists, and many are without even knowing the "concept".
believe it's immoral to leave behind nuclear waste for future generation to care for.
Do you understand that nuclear waste is just a kind of pollution, which should be compared with other pollutions such as C02 emissions.
It is estimated that C02 kill 1000000 humans per year
Nuclear wastes kill 0 human per year.
It has not killed even one human in all nuclear history.
Most people who talk about nuclear waste don't know anything about nuclear wastes... And they don't realize they talk about something they don't know.
With recycling technologies such as what France do since decades, nuclear wastes generate useful byproducts (MOX).
France only generate a few tons of nuclear waste per year, recycle more than 90% of it.
0.1% of the wastes are "dangerous" which means don't be exposed to them more than a few days if you don't want to increase your ageing.
0.1%.... That's a few kilos per year.
The rest stop being radioactive 10 years after production.
Those 0.1% are safely contained since 70s and will never be an issue.
Geological containment is only a marketing for pleasing those with the irrational fear described in my last comment.
