We drink coffee and do not think what a train, woven from the history of the earth and the growing up of mankind, stretches from a small cup with a fragrant drink. Do you know how old a coffee tree is? 27 million! It turns out that it needs multi-tiered forests that protect it from both thirst and high humidity. Do you feel what we are losing by cutting down forests? And the DNA of coffee and humans is almost equal on chromosomes: 44 and 46, respectively.
