Sorry, but we are all appointed to die, that is a fact and nothing we can do to solve it.
I guess that's one way of looking at it.
lawnscaping and lawn hygiene are a problem en masse, because they're basically a variant of monoculture which speeds extinctions.
I was being completely serious. This is why I recommend people allow their backyards to grow partially wild. Lawns are huge source of monoculture. The benefit of any nearby natural preserves (which will go down as a result of climate change) will be higher the more 'native' habitats are around it. That's just the nature of extinctions. There will just be some species that
thrive more or 'hold on by their toenails' more easily if there's a larger habitat or a larger native ecology. Or even native-esque.
Sometimes people like the look of 'non-native' plants around their houses. It's not that it's 'bad', it's just that they're 'not good'. Now, with
edge effects, non-native diversity will always be better than monoculture, but that's about it. Non-native approaches monoculture for all intents and purposes. Unless native organisms can either thrive or (at least) benefit from the non-native plant, it might as well not be there. Now, that said, nature is
diverse, so there will
always be native organisms
wherever you look.
I tend to think in terms of extinctions, where the primary cause is shrinking habitats and knock-on effects. Who knows what the critical linchpin species is in your area? As well, because of natural selection 'buying time' while a species holds on by its toenails can be of benefit. So, the native wasp who
barely holds on due to your flowerbed is going to be food for some aphid that feeds some native bird that surely cannot live in your flowerbed. There're are a LOT of species that are currently holding on by their toenails, because habitats are shrinking. The preserves are mostly just a noble attempt, but they're insufficient.
"human corpse: freeze-dry it, shatter the brittle corpse into white powder, then compost"

I might be wrong, but it seems to me that a proper freeze-drying could take up just as much (or nearly as much) energy as a cremation.
Space concerns can be addressed without "ending unsustainable cemeteries"
It's a bit rough traditionally. Graveyards are a strong historic tradition, but from a time when population sizes (and thus death rates) were much, much lower. So, sadly, this might be one of those areas where "the free market solves it". As the price of graveyard space goes up, economical alternatives will be more and more sought by grieving relatives. We haven't buried someone in my family for more than a couple decades, and the last burials were of family members living in small-town Saskatchewan. I currently live in a city (Halifax) with a great deal of space devoted to graveyards, but they're (seemingly) mostly full. I don't know what the city-folk do with their deceased loved ones.
