According to research, more than 50 counties in China are slowly sinking. Experts compare land sinking to a chronic disease, that goes unnoticed but remains dangerous. More than 50 county-areas in China are suffering from land subsidence, while the total area of land lower than 200 millimeters has reached 79,000 square kilometers. Parts of the cities may be submerged under water in the future. The areas which have the most severe situations are the Yangtze River Delta, the North China Plain and the Fen-Wei basin. According to the China Geological Survey, in the past decades, the economic losses caused by land subsidence in the Yangtze River Delta have totaled up to 315 billion yuan. The economic losses of the North China Plain amount to 332.8 billion yuan. As large as 79,000 square kilometers of land has dropped more than 200 millimeters, Zhang Zuozhen, vice-president of China Geological Environmental Monitoring Institute, told CCTV. The subsidence mainly occurs at the Yangtze River Delta, North China and plain areas covering North China's Shanxi province and Northwest China's Shaanxi province, he said. The lowering of ground is mainly caused by excessive exploitation of underground water, which has led to damage of buildings, bridges, underground pipelines and dysfunction of urban drainage system, according to the report. The State Council has approved a plan of preventing land subsidence from 2011 to 2020, which was jointly created by several ministries and commissions including Ministry of land and Resources.

I've been talking about sea level rise as a serious thing to come and ironically i received a little brochure talking about flood zones. In miami beach where i live, during high tide the streets are flooded now. I'm pretty sure miami will be flooded eventually and this goes to all other coastal cities.

could it be because they've grown so much rice and burnt away the substance after harvest? Mass is lost this way, soil does go down over time.
