Yes, plants grows massively faster with higher CO2, plants has been CO2 starved for millions of years now but add it in labs and you can see plants growing more than 100% faster. Probably the reason we see less mineral density in crops today, CO2 levels has risen so they grow faster but mineral supply is the same. So probably not very beneficial, we aren't lacking in plant calories as is.
