The food that is patented isn't essential to life, though. Essentially all of humanity has lived all of it's lifetimes without this modern varietal of nectarines just fine.

There are certainly tons of cases where modern developments might be actually essentially to life or extend life like with medication, medical devices, temperature control, moves to modern electric technologies versus combustion to reduce pollution, etc. How do we incentivize new medication development, something way more lifesaving than nectarine varietals, without some period of exclusivity? At least there, twenty years from now, the solutions will be more accessible versus never developed.

This relates in no way to the availability of food, which in the US at least is high enough that starvation is the preserve of the terminally ill, anorexic/bulimic, addicted and indigent, rather than people who can't find calories to eat. This is almost entirely an economic issue that would be a lot easier to discuss without the incessant and repetitive emotional comments.

What does this have to do with anything? Not all species are patented.

If farmers dont want to pay for patented species, then they will grow unpatented food, which you can eat.
