Superphoshate is a fertilizer produced by the action of reacting concentrated sulfuric acid on ground phosphate rock. Calcium sulfate is a considerable waste produce of this process. Ca3 (PO4)2 + 2H2SO4 → Ca (H2PO4)2 + 2CaSO4Superphosphate used world wide by as a fertilizer the farming industry and gardeners. It increases plant production by as much as 106% as long as the plants are getting the required amount of water for normal plant growth. Super phosphate does little if nothing if there is no

China’s Pollution Problem China‚ one of the worlds largest industrial powers‚ is now facing a difficult situation. China’s industries rely largely on coal power which emits harmful gases‚ causing intense air pollution. The Chinese government‚ in fear that the country would fall in a recession‚ has not done much to stop these industries‚ so China has become the second largest greenhouse gas emitter in the world. The types of pollution created by this include air pollution and water pollution‚ both

quadrupled over the past 150 years. This increase can largely be attributed to grazing and cropping expansion in the catchment‚ which has also resulted in the loss of native vegetation and wetlands. Nutrient loads have also increased‚ encouraging algal blooms‚ which‚ in turn‚ provide food for larvae of the devastating crown-of-thorns starfish. In addition‚ nearly one-third of the reef is now exposed to pesticides. ------------------------------------------------- Overfishing Not only is the reef
