Tea in Central Sri Lanka-high altitude and rainfall ideal for the plant. Yes, but the replacement of broad leaved hill forests by less dense tea crop is ideal for the soil to be eroded and contributes to landslides. But this is now given a critical gigantic push by the combined power of the reservoir contents of the world and the simultaneous, instantaneous,cumulative effect of the changes in the world's reservoir contents. This is of the order of 250 billion cubic meters at any instant driven by the water consumption needs of the entire world. When the landslide is about to occur, the entire brunt of this change is suddenly applied as a surge of some 560000 terawatts as if a great earthquake of magnitude 8.6 MM(moment magnitude) had occurred there. The power impulse was more than 2 million times the All-India electrical capacity of a quarter terawatts! A terawatt is a thousand billion watts, the rate at which 6 billion human beings do heavy work for a short time. The moral from this repeatedly applied blows on modern civilization(MC) is clear. MC is making khudkushi(suicide). This kind of growth oriented development breeds only insolvency and extinction. Go normal. Live in harmony with nature. To cut off dense forests on steep hillsides to enjoy a cup of tea is to be buried in terrific earthquakes, volcanoes and landslides. Reforest Mother Earth to Live!
