The comment is referring to finding something to replace the Haber-Bosch Process, which is mostly fossil fuel driven, which makes most of our food itself dependent on fossil fuels.

Unrelated to the above, except in the mix of sustainability and agriculture - there are a bunch of companies working on bacteria to fix nitrogen for crops without requiring separate fertilizer similar to how legumes do it. I think Pivot Bio is the furthest along in the space - they’ve got a commercially available product - but it’s an active area of development in the industry right now.
