Answer:
China's water supply has been contaminated by the dumping of toxic human and industrial waste. Pollution-induced algae blooms cause the surface of China's lakes to turn a bright green, but greater problems may lurk beneath the surface; groundwater in 90 percent of China's cities is contaminated.Many times in these cases, the pollution is caused by chemical dumping from nearby factories. Dumping of industrial chemicals, agricultural waste, and urban wastewater has contaminated China's water resources such that over half of all rivers in the country are unsafe for human contact.China's sweeping campaign to cleanse filthy lakes and rivers has improved water quality in some regions — but dirty water still plagues parts of the country. China began tightening environmental rules in 2001, in an effort to cut water pollution emitted by cities, industrial facilities and farms.Dam construction has played significant roles in flood control, irrigation, navigation, and energy supply; however, the enormous negative effects, such as landslides, ecological problems, and water quality decline, could surpass positive gains.
As we write this tip sheet, the government just approved the merger of Sprint and T-Mobile, which are two of the four biggest cell phone carriers. If Sprint and T-Mobile complete the merger, there will be three major carriers—AT&T, Verizon, and T-Mobile (which is what the combined Sprint and T-Mobile will be called). These carriers provide the best coverage and are the main players in the industry. Their coverage and plans differ from each other, so you’ll want to do some research to see which one provides the best coverage in your area, and which one offers the data plans that best meet your needs. But these are not the only options. There are other, smaller carriers that may provide coverage in your area, and offer plans that cost a lot less than the plans offered by AT&T, Verizon, and T-Mobile. How do you find these other carriers? Try Googling for information on carriers and plans from reputable sources like Consumer Reports. Here’s a link to a 2019 Consumer Reports guide to low-cost cell-phone plans. Consumer Reports updates this information yearly. You can also get good information about plans from Whistle Out
