The earths resources are running out, who deserves to live and die?

this is something we may have to consider in the future, and it may even be within the next 100 years and therefore possibly in my lifetime. The earth only has finite resources and yet the worlds population is expanding at a mive rate. At some point we will have too many people. Solutions could be banning people from having babies, euthanizing people over a certain age (like in the movie logans run), and/or people who cannot benefit society (mental/physical handicapped aswell as below par intellect). These all may seem unthinkable but they are all possible questions that will be considered in the future. These thoughts scare me, what do you think will happen? Will we find a way to avoid running out of resources? Or will we be forced to take other extreme measures? If so which ones?
