Organic farming isn’t pesticide free, they use a range of pesticides, and usually at a higher volume than normal farming methods, because they don’t work nearly as well.

Additionally, organic farming tends to produce lower yields (19-25% lower on average) than traditional farming, meaning you need to actually use more space and resources (water, fertilizer, plus application of both) for the same benefit.

Organic farming can be good for some things, like fixing already-damaged environments, but it’s not a silver bullet by any means.
