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.
Hi there!
I'm glad you've joined Brainly.
During the rise and peak of Islam, a very structured and organized law system was established based according to the Quran and religion which had been highly depended upon. Due to this, many people did not commit crimes, steal, or lie, knowing that their Lord may punish them. Therefore, this all comes down to establish the very core of the matter: the caliph set laws and punishments which were all agreed upon by scholars, community elders, and respected Muslims.
The caliphs of that age had a system which they called Hokm Islami. This translates to Islamic rule without force. Later, the Ottomans established the forced rule for all, based on certain groups and religion types.
Abu Bakr set many limits on himself as other Caliphs had done. This included equality of wealth for all. There had been a treasury which they called "Bait Ul-Mal" , which the Caliph was not allowed to take money from, unless it was to help the community or poor folks. The Caliph also limited himself to water and basic food to live. He lived in a humble home as other men did.
Aside from money, the Caliph Abu Bakr also made sure that he did not order anything unless it was backed by the Quran, and agreed upon.
I hope this helped. If not, please comment below and I'd certainly be glad to elaborate and add to this description. Thanks! :)
