Of course it won't be sweet as.
But if we do **** all it will definitely not be sweet as, and there will be even less chance of developing any sort of sustainability for the future.
We can't control what others do, but we can control what we do.
In doing so, we can potentially develop practices and technologies that are viable for other places to adopt, so that they don't have the excuse that it's too hard.
If we had listened to the experts, we would not have been able to prevent these fires.
However we might have been able to control them better, with better resources.
Instead, because you can't admit to climate change, and you can't admit to government having in a role in large scale issues, we have this situation.
If we had listened to the experts, we mightn't have most of the state ****ed by drought. Drought, yes; but better water management to take the edge off it, and maybe even not have towns that don't have a drop to drink.
If we had listened to the experts, we might be on the way to developing sustainable energy tech, instead of killing off biodiversity, polluting what little water there is left, both of which is pretty important in having sustainable agriculture.
Signing up to targets, and meeting them through effort as opposed to lip service, these things help to encourage better practises.
Not bothering because its too hard or it's probably futile leads to maybe a bit of short term gain for some sectors - none of them vital to anything - and longterm pain for most of us.
