Shipping is a massive consumer of all kinds of oils, especially fuel oil and diesel.
Want to make a real difference? Stop shipping shit around the world, accept there are growing seasons, grow and manufacture locally.
Suddenly the number of massive ships constantly churning through hundreds of gallons of fuel per hour, and trucks moving shit cross country, would seriously dwindle.
If it isn't clear by now - the power brokers of the world love moving manufacturing to wherever they've made a political deal, and don't give a fuck about the rest of us.
Do I like getting off-season fruit in December? Sure. Do I need to get it from Chile? Fuck no, greenhouses are a thing. How the hell is it cheaper to move that shit 10,000 miles than to grow locally in a hot house? Clearly someone's getting paid.
Sorry about the rant. Shipping is the elephant in the room whenever I hear people complain about cars.
