I'm preparing a talk on resources for French civil servants (now they will have to attend one presentation on #climate, one on #biodiversity, and one on resources as part of a mandatory continuing education) and I thought I would share the images I'll be using here, as I find some of them are quite nice.

So see below for some impressive visualizations on our #resource #consumption.

I guess many may have seen these two, but I had to show them: it's been a few of years since we estimate the mass of human-made stuff since 1900 has exceeded the global biomass.

That's right: the weight of all the things we made is heavier than the dry mass of all living things on the planet (including viruses).

And at the speed we're increasing it, we'll exceed the wet mass (roughly 2.5 times this) in roughly two decades; less if we keep accelerating.

@tfardet funny how we mine 8 billion tonnes of coal a year globally but the fossil fuel and media companies have us convinced the “real” environmental damage is being done by mining technology critical minerals on the lowest tier of that mining chart whose amounts mined annually measure in thousands of tonnes, not billions.

Really puts things in perspective.

@bascule well, rare metals do have higher impacts per gram compared to fossil fuels, but given the amounts extracted, the overall impact is indeed much higher for fossil fuels.

One just has to see a coal mine to understand the scale of impact we're talking about.

But I'll talk in more details about that when I get to the notions of "ecological rucksack", material requirements and flow analysis, etc.
