But perhaps (5)what is most significant is the way in which people have worked in harmony with nature to make these terraces and grow rice.The terraces are cleverly designed, with hundreds of waterways that connect with each other.During the rainy season, (6)it is along these waterways that rainwater moves down the mountains and into the terraces.The sun heats the water and turns it into vapour.This forms clouds (7)from which rain falls down onto the mountain terraces once again.These terraces also provide a perfect environment for birds and fish, (8)some of which feed on insects that can harm the rice crops.
