Organic and recycled, why does it cost us more?

I am doing my best to eat well and be kind to the earth however I noticed a huge difference in my grocery bill while doing so.

Does it cost more to put no chemicals on food or is it simply a supply and demand thing?

Does it cost more to recycle and not use bleach then to use bleach and create new paper towels?

Am I over complicating this? I am guessing it is a supply and demand thing however it makes no sense to me that Organic Radishes cost $2.00 more than regular Radishes. Same with paper towels. I purchase the new ones that are bleached for .79 or purchase the recycled ones for $2.49 a roll that don’t even have as many towels and don’t absorb as well?

Seems backwards.
