You know that forgotten lettuce wilting in your fridge? Turns out it's not just a waste of money, but a sneaky contributor to climate change too. When food ends up in landfills, it doesn't just disappear – it decomposes and releases methane, a greenhouse gas way more potent than CO2. And we're not talking small potatoes here (pun intended). Globally, if food waste were a country, it'd be the third-largest emitter of greenhouse gases! Crazy, right? The good news is, we can all pitch in by planning meals better, composting, or even getting creative with leftovers. Who knew that cleaning out your fridge could be an act of climate heroism?
