Really good book, it really shows off the issues we are facing, the solution that we can work out to improve a better lifestyle to the population who lives in urban areas, without suffering too much on pollution, high rates of vegetables and make agriculture even greater by value the professionals, For example: alternative food for students and employees in big commercial areas such as factories and shopping centers; who many are vegetarians or make more diverse health options to make a better health life.
Agriculture has grown so fast due to technology, so i guess we should use that growth and expand more in urban agriculture; food garden on shopping rooftops or more community gardens around the world to get more healthy choices which leads to a better life to people and a big rise in economy improvement in their houses = savings - ( food and gasoline (less pollution) ).

I recommend to any professional in agriculture industry, gardeners and landscape designers/architects to get this book, I'm still learning a lot by using this book, which will certainly give a great help in future projects ! 5 stars
