Old bikes were definitely not built for tall folks. I tried the 90s mountain bike and I wanted to love it, but the frame was just too small so I went back to my XL 29er and im happy as a clam. Im jealous of the average sized people that can make those bikes work for them though.

Im not a nuclear bro, but a vast majority of the planet’s Uranium is mined in Australia and Canada and both countries have pretty massive reserves. They have strict regulations and safety surrounding uranium operations. Naturally occurring uranium doesnt even pose much safety risk on its own, its the Radon that is generated by decay that causes problems for humans. Im not too familiar with how uranium mining is done but I imagine Radon risks can be mitigated pretty effectively with ventilation.

0·13 days agoHard agree from me. Cars are such an inefficient use of resources its crazy. If I had it my way we would all get around by train, tram, or bike.
Ok I think I get it now, it is basically the flaw behind resource allocation through capitalism. The cost of supplying these mining towns does not match their ability to pay for those supplies after the mine goes bust. Do I have that right?

0·13 days agoIm a Canadian geologist so I obviously dont have any personal stake in this but I do want to share my thoughts.
I think anti-mining sentiment is understandable in most places but not always justifiable. Lithium mining is absolutely required to transition from fossil fuels. Unless the number of cars on the road is greatly reduced, replacing them with BEVs will require significant amounts of lithium or improvements to Na ion batteries. There is not enough lithium available to get by just on recycling.
The question then becomes: where should this lithium come from? If it is not mined in western countries like USA or Canada, it will be mined by China or developing countries. In this comparison, who has better environmental regulations? Which countries have more human rights abuse?
If we decide that we can mine these deposits in the west, there is still a question about where they are mined. Do we extract lithium from basinal brines? My understanding is that these are generally more environmentally risky than extraction from pegmatites (the deposit type in New England).
The final question becomes, which communities will have to accept this mining? In Canada, most of the time it is indigenous communities that suffer most of the negative impacts of mining. There are many benefits to the communities too (usually), but the indigenous communities do not have nearly as much political sway as say rich cottage owners might, so their preferences and desires often get steamrolled by government in the name of “progress”.
The unfortunate reality is that if we want to get rid of fossil fuels, we need to do a lot more mining and extraction or come up with some serious technological and societal innovation. In a globalized economy, saying that you dont want mining near your home means that you want some other people to deal with the potentially negative consequences of it. I am not saying that we need to allow all mining everywhere, but these are important ethical considerations that we have to make when talking about how we want society to progress.
Sorry for the rant.
This is an interesting perspective I haven’t heard before. Are there historical examples of this happening?
Oh I see, thats very interesting thank you! Are you an archaeologist, or just someone very interested in stone-age history?
Where do European Neanderthals fit into this story?
I feel this way after finishing grad school and going into industry. Nobody wants to just nerd out

Climate@slrpnk.net•Farming insects mostly replaces already low-impact plant ingredients, not high-emission animal products. Farming insects is “Not Recommended” as an effective climate solution.0·3 months agoI found roasted crickets very bland and tasted like oats. I assume thats what they were fed.
I’d probably eat them if they were extremely cheap and accessible but I dont see the point when chickpeas, beans, lentils, and soy all taste better, are cheaper, and easily sourced.


This is pretty cool. Is it similar to how bamboo threads are produced?
