Nid oes un ffordd o ymateb i’r materion hyn – mae gofyn cael dull gweithredu amlochrog ac amlasiantaethol sydd wedi’i ddatblygu drwy gydweithio ar draws sectorau, ar draws adrannau'r llywodraeth ac ar draws gwasanaethau.  Nid yw atal a chefnogi anghenion iechyd meddwl a llesiant y boblogaeth yn rhywbeth y gall – nac y dylai – y GIG ei wneud ar ei ben ei hun.
There is no single response to these issues – they require multifaceted and multi-agency approaches, developed through collaboration across sectors, across government departments and across services.  Preventing and supporting the mental health and wellbeing needs of the population is not something the NHS can – or should – do alone.
