Retired IT entrepreneur sets out to change the world: The Protein Crunch

I’d happily give this a go. As long as the pig slurry and maggots are down the food chain a bit. I don’t fancy eating them every day.
But they don’t make it easy for you. I liked the book jacket design, but it seems to suggest that mankind is killing his own planet, without offering any hope for our redemption. Presumably, our redemption is the subject of this book.
OK, so civilisation is on the brink. Got that. Where’s the happy ending though?
The book claims to reveal the shocking truth of how we have abused the very ground we stand on, the water we drink and the seas that cover our planet. Well, OK, that is generally well understood.
Jason Drew said he has a plan. That’s what I want to hear. Show us the maggots Jason. Show us the maggots!
But first, we have to plough through more pre amble that tells us   nothing new. It’s all true, it’s shocking. But tell me the bit I haven’t heard before. The bit that describes how we can solve the problems. Show me the maggots Jason! Show me the slurry!
“These natural resources have become critically degraded at a time when our expanding population needs them most: WE MUST ACT NOW. This accessible, mass market bestseller offers radical new explanations, arguments and solutions to the way we live and treat our planet.”
Yea yeah, OK. But show is the maggots! Show us the maggots!
“PART ONE Elements of the Eco-Crunch Water Land The Seas”
No, I don’t want to work through that. Just show me the slurry
 PART TWO At the Limits and Beyond. Cities and Population Growth Animal Cities and the Agri-industry
PART THREE They promise, begins to start describing what The Protein Crunch is, and how it can end world hunger.
I can’t wait that long!
To be honest, I haven’t read all the book yet. It’s fascinating. But at the same time, I wish they’d give me some incentive to keep reading. Maybe the next version will do this.
Show me the happy ending Jason. Or give us a hint at least.
