This chapter explores the process of photosynthesis in plants, discussing how plants split water into hydrogen and oxygen and the potential for using hydrogen as a clean fuel alternative. It also examines the use of x-ray lasers to study photosynthesis and the mystery of the missing carbon in the atmosphere. Additionally, it delves into the identification of carbon sinks, focusing on boreal forests in the high north and the presence of unexplained craters and explosions in Siberia.
