I learned about reusing (carefully cleaned and dried out) juice bottles to use to store dry foods like lentils, rice, flour, sugar, etc. I am excited to do this. I am also using milk jugs but some people would only use PETE plastic. Here are some links.

it should keep insects out but rodents can chew through the plastic. if you have a rodent problem you can just store the jugs of food in thicker plastic containers though
I think nuclear will be necessary at least temporarily in order to get off fossil fuels fast enough to stop climate change maybe after that we can try for more renewable energy sources and rely less on nuclear power luckily there seem to be some recent technological advancements where it has been discovered how to use the waste to produce more energy another way but you’re right, I am concerned about capitalists cutting corners to save money and causing deaths that were entirely preventable
