High Tech Harvest: Understanding Genetically Modified Food Plants

I'm a jobless agronomist.I read this good book, here in Brazil.This book is concise and easy to understand.It isn't only for agronomists or farmers.It is also for general public.Even the language is for the general public. Failures of this book are small.To example, on page 146, this book has this sentence:"For example, the once-powefull insecticide DDT lost its effectiveness a long time ago".In fact DDT didn't lost its effectiveness.The DDT's ban came , because DDT was saving "too much" lifes in Africa, Asia and other places with colored races. The small chapter about plastics from GMO, tells that they are too expensive compared to oil.Well, when this book was writen, oil had a price smaller than the half , compared to oil's price of today.Even with oil at so big price, plastics from transgenics costs too much; at least for general aplications.Agriculture can produce plastics without the use of GMO.If you have a biodigestor, you will have methan(CH4).Then almost all oil and natural gas plastics can be produced using this gas.
