That is the book I've been reading. The book is kind of about agriculture <strike>book</strike>. At this time, I'm interested in reading books about agriculture and health.
<strike>There are</strike> I have  so many questions after reading those books. Why do we have to pay a price for costly of organic fruits or vegetables while they don't use chemicals, when they don't do anything except watering? ( For vegetables and fruits are grew by chemical are cheap, even cheaper by the time ) Can you calrify this sentence? I don't understand what you are trying to say.
There are 2 people who are Japanese farmers, they grow plants <strike>as</strike> in natural ways. They don't use fertilizers or chemicals, <strike style="">grasses are filled in their gardens</strike> (their gardens are filled with grass) but their plants are still growing well. Fruits are fresh, <strike>strong taste and good smell</strike>. (they are tasty and smell nice)
Why don't people stop using chemicals in agriculture?

I hope this helps. I will update later if I missed anything.
P.s. I don't know why they use chemicals in agricultural products. I really hate the fact that they use chemicals in agricultural products
