That did and in some places does still matter. Homes moving away from heating with coal to natural gas reduces smog. Thus it is seen as clean energy. Because everything is cleaner in the true sense of the word clean. Green is often a better predictor.

Personally I like charging up batteries in the Nether and bringing them back so the emissions don't matter.

Nothing inherently, you can go ahead and eat apples from your apple tree.

The main issue with "organic" foods is that the term is usually very badly regulated. Sometimes there is no difference between "organic" and "non organic"... besides price. Sometimes "organic" foods use very ecologically unfriendly techniques, or are grown/processed in countries where supply chains are not inspected anyway.

Then there's the fact that if something is different, it may not always be an environmental or health win. Growing your food in 30cm of water may be one organic and traditional way to avoid using pesticides (see: rice), but doing that with corn in the middle of Arizona would obviously be a terrible idea!

Anyway, overall I don't think organic foods are worse if you're well off enough that the price is not an issue. But you shouldn't feel personal guilt for buying whatever's cheaper, because quite often the alternative does not justify the price anyway. Eating truly "organic" food unfortunately requires a lot more involvement than picking the green package at a national supermarket chain.

It's a bullshit marketing term to appeal to pseudoscience and anti-intellectuals.

It's a heavily abused and arbitrary marketing term that doesn't actually indicate anything about what the food is made of or how it's made or grown. It also doesn't indicate anything about how healthy the food is or how good it tastes. At most it's slightly better for the environment in some areas with some brands when used properly, but even then regulations are too lax and inconsistent worldwide for it to be a trustworthy label.

Depends on where you live. As far as I know the term is not well protected in many countries, so it means next to nothing there.

However, I live in the EU / Germany, where we have several organic farming standards that are all fairly strict. Generally, organic actually means organically produced food here, grown without artificial pesticides, chemical fertilizers, and so on.

It's more expensive, and it's typically not that much better than inorganic.

Just out of curiosity since I assume you know more about this, is "plant based" the same as vegan? Because that's the hip new term but I've always wondered if they're equivalent or if they do have some animal products which is why they're dancing around the word vegan. I've never gotten a straight answer from the people at the store/restaurant.

Because I doubt there is anything we eat that's non gmo, we have been influencing the genetics of plants around us for centuries.

For example saying you only eat organic watermelon is fucking stupid, look at how it looked 2000 years ago and how it looks now.

OP, see here how it's done.
