Reduce, reuse, recycle. In that order.
If you don’t need to, don’t produce something. Chocolates don’t need to be all individually wrapped inside of yet another wrapper. Transport should be mostly by public and active transport (though we also need better city planning to help enable this), and private motor vehicles can, at this point, mostly be converted to the less-polluting EVs. That kind of thing.
If it’s been produced, rather than throwing it away, find ways to reuse it. Coke should be taking in glass bottles, washing them, and putting more coke back in it, rather than producing new bottles all the time.
If something has been produced and cannot be reused, we should try to find ways to recycle it. You’re right that recycling is bad, but that’s mainly true of plastics. Glass and paper are far more easy to recycle, if collected effectively. Which is also why the move from glass and paper products to plastic is such an environmental disaster, brought on because companies don’t want to spend the larger cost of producing those products, or collecting them in to effectively recycle the glass.
Safe, sure. Efficient? Not even close.
It’s far, far more expensive than renewable energy. It also takes far, far longer to build a plant. Too long to meet 2030 targets even if you started building today. And in most western democracies you wouldn’t even be able to get anything done by 2040 if you also add in political processes, consultation, and design of the plant.
There’s a reason the current biggest proponents of nuclear energy are people and parties who previously were open climate change deniers. Deciding to go to nuclear will give fossil fuel companies maximum time to keep doing their thing. Companies which made their existence on the back of fossil fuels, like mining companies and plant operators also love it, because it doesn’t require much of a change from their current business model.
