The main tenet of this book is that climate change will necessitate the migration of up to three billion people in the coming decades. The entire earth's geography will be redrawn and those areas which are tropical or warm such as the Caribbean, Africa and Central and South America will not longer be able to sustain life. This will have their inhabitants moving to areas that can be lived in. But how would this work?
The author believes that the only way for humanity to survive is for those currently living in areas that will be sustainable will have to completely change their ideas about immigration. They must welcome those seeking new homes, whether it is former farmers from their own country or people from other countries who are totally different in their culture, language and appearance. Governments must support the immigrants with food, child care, shelter, health care and job training.
Food will be totally different. Humans will move to a plant-based diet and entire industries such as cattle and chicken production and fishing will disappear. This will free up more land for farming plant crops. Humans will get their protein from eating such things as insects or lab grown food. Many current occupations will disappear while new ones will be developed.
Gaia Vince is a science writer and broadcaster. While she provides many novel ideas, I find it difficult to believe that humanity will change their attitudes, occupations, diets and energy production as quickly as she sees it happening. She believes that all energy production must be green energy by the 2030's. I can't imagine humanity being happy with a insect-based diet. Most importantly, I find it difficult to believe that attitudes towards immigrants will change as rapidly or thoroughly as the author believes is necessary. Countries around the world are becoming less welcoming of immigration rather than more welcoming as more and more countries are moving towards the far right in terms of immigration. Still, these are interesting and provocative ideas. I listened to this book and the author was the narrator. Her voice added to the mix as it was calm yet definitive in her suggestions. This book is recommended for nonfiction and science readers.
