Since 1950 there has been a steady increase in mental illhealth across the population. At the same time there has been a similar steady decline in IQ.ampnbspThere is strong evidence of dumbing down right across society. If this is allowed to continue it will be the greatest threat to the sustainability of the human race even greater than the more visible threat of climate change.ampnbspThe Global Mental Health Crisis is a direct result of the fact that over time the actual size of our brains is getting smaller. This is a historical fact but is entirely reversible with better brain nutrition. This has now reached crisis proportions.In 2023 The European Brain Council recognised that Brain Health conditions have become a globalampnbsphealth emergency. Back in 1972 Graham Rose wrote in the Sunday Times Unless action is taken to care for the nutrition of the brain We will become a race of moronsampnbspAuthors Michael A Crawford and David E Marsh have both devoted their lives to this vital area of research. This book is their legacy. In painstaking detail they put the case of how to reverse the Global Mental Health Crisis. With greater awareness of the problem its cause and the solution required to make a change their message could not be clearer.ampnbspampnbspBy reading this book you will not be able to say We didnt realise.This book may contain complex research and the result of detailed research but the message is simple. And so is the action we all need to take.We also explain the role of the environment in the evolution of the brain leading to early Homo sapiens with a brain capacity of over 1600cc and explain why it is now only 1366 cc and mental illhealth is escalating. The concepts in this book have been fiftyone years in the making. They cant wait any longer. There is no more time.ampnbspPresented with these incontrovertible facts it does not need a rocket scientist to work out what will happen if these dumbingdown trends continue Fortunately solutions are availa
