Unless they’re being replaced at a rate equivalent to or greater than the rate we’re using them, they’re being diminished.
Oil and coal can’t be produced naturally in a fraction of the period we’ve converted our lives to depend upon extracting them from the ground.
They have to be diminishing.
Forests are being destroyed all over the world, notably in places like South America and South East Asia, with giant fires that pollute the atmosphere, to the extent that it’s a major issue between Indonesia and Malaysia. It’s the planetary equivalent of smoking cigarettes flat out and chopping out alveoli in our lungs every second of the day.
Whatever the reason, the polar ice caps are melting.
Nobody thinks they can live on a creek and throw their garbage and pour their sewage into and it’ll still be okay downstream, but those who assure us that there is nothing wrong with the planet assume that we can do the same to the planet on an immensely larger scale and none of the shit will ever clog up the planet’s systems.
I don’t think one needs a Ph. D. in anything to work out that every system gets overloaded if crap is constantly pumped into it. It’s just a question of whether one wants to accept that, say, the river has had a fatal dose of crap because dead fish are floating on the surface; no fish are caught there any more; the algal bloom kills things in the water and people who drink it because deforestation or irrigation diversion etc upstream has destroyed natural flows to flush the river; or it’s just an aberration that will pass when the missing El Nino pattern restores itself.
How many of the doomsday predictions of this, that is, or the other resource running out by such and such a date have been even close? None of them.
It is pointless to cripple ourselves on the basis of a nonproblem (or something that may become a problem in hundreds of years time) just because it makes us " feel good" about doing something for “the children”. The cure is often worse than the supposed disease – for instance, DDT was banned on the basis of some extremely wonky research, and millions unnecessarily died from malaria as a result. It is now being reintroduced, but are those responsible for the damage caused by banning it being held responsible? No. Are they even being made to say sorry? No.
I share your scepticism, but without the scienctific knowledge to evaluate the risk. Which puts me in the same camp as about 95+% of science educated people. And the other 5% can’t agree.
I remember the Club of Rome in the 1970’s predicting disaster not too far off. And sundry books about impending catastrophe, some written by scientists.
I’m not convinced that global warming is even an unusual event. We’ve only had records for less than the blink of an eye in human occupation of the planet, which isn’t even the blink of an eye in the planet’s history. The current experience may just be part of large scale normal processes over geological time unrelated to human activity.
It might also be a consequence of human activity, and common sense suggests that human activity has at least contributed to it.
So I think we’d be stupid to continue as if there’s no risk.
We can’t do any harm by taking a risk-reduction approach, except on an economic basis.
Which comes back to my consistent point that economics, money, whatever people want to call it, ain’t the be all and end all of existence. Although if we don’t wake up to ourselves it might be the end all of existence.
