Read the passage below and decide whether the statements are TRUE or FALSE?

Light pollution is the excessive, misdirected or invasive use of artificial outdoor lighting. Mismanaged lighting affects the environment, energy resources, wildlife, humans and astronomy research.

Light pollution is not a new phenomenon. Over the last 50 years, as countries became affluent and urbanized, demand for outdoor lighting increased and light pollution sprawled beyond the city limits and into suburban and rural areas. This form pollution is now prevalent in Asia, Europe, and North America, particularly in cities like Los Angeles, New York and Washington D.C. In 2008, National Geographic magazine named Chicago the most light-polluted city in the United States.

However, the most light-polluted spot in the world is Hong Kong, China. In March 2013, the University of Hong Kong named the city the most light polluted in the world. A study by the university found the night sky in Tsim Sha Tsui, an urban neighborhood in southern Kowloon, Hong Kong, to be 1,200 times brighter than a normal urban city sky. Luminous pollution of this magnitude is on the rise worldwide. In a 2010 article from the Ecology and Society Journal, Hölker and others stated the use of artificial lighting increases by 20% each year, depending on the region, and noted there is an urgent need for light pollution policies that surpass energy efficiency to include humans, animals and the environment.

There are many causes that lead to water pollution.

Industrial waste consists of some kinds of chemical substances such as sulphur, which is harmful for marine life. Lead is known as the main reason for cancer disease. Cancer has become a popular disease in several communes which are called “cancer villages”. Another cause is the awareness of citizens, people always use water for many purposes and then they dump waste water or garbage directly into rivers, canals and ponds and so on. In 2004, because of a bird flu outbreak in Viet Nam, people threw poultry to water body that made water highly polluted.
