I read that throwing food in the trash is bad for the environment cuz it produces (I think it said...) ?

It has to do with aerobic vs anaerobic decomposition.

If you throw your, say, apple core in the compost, there's a good chance (unless it's a very large and/or poorly tended compost heap) that it will decompose aerobically. It will be eaten by insects or worms, or by fungi, or otherwise eaten by things that breathe oxygen and give off carbon dioxide. Plus, after what's left becomes dirt, you can use it to improve your garden.

On the other hand, if you throw your apple core in the trash, it will get buried, pretty quickly. That means it won't have a chance to decompose aerobically, since there will soon be little or no air around it. Instead, it will decompose anaerobically. Anaerobic decomposers don't have oxygen around to turn carbon into CO2, so they just turn it into methane.

Food breaking down produces methane whether it's in the compost bin or the landfill (or for that matter even being digested in your stomach!)

Composting will allow much of the nutrients in the food to be recycled to grow more food (or trees/shrubbery/lawns,etc.) But OTOH many landfills have ways of recapturing the methane and recycling it. So there's no one perfect solution. 8^)

Not true. Nothing wrong with the environment/ all non solids that rise into the upper atmosphere separate into nothingness. all season have returned to normal since Global warming ended in 2012. Mike

You are correct. It will produce methane or CO2 and the methane it produces quickly oxidizes to CO2 anyway.

Why do those denialists need to drive SUVs and have accidents in their pants every time the toilets back up an nuclear power plants. Throwing food in the trash is so much cheaper than the former and so much less embarrassing than the latter.

If you see food in the trash you should eat it.

The planet is at stake.
