• True

• False

Why do some industries contribute to water pollution in cities?

• Lack of workforce

• Poor regulation

• High taxes

• Limited infrastructure

What is a major cause of water pollution in some cities?

• Inadequate infrastructure

• Lack of population growth

• Industrial development

• Excessive regulation

Water pollution is a problem in some cities due to:

• poorly maintained sewage and waste management

• high taxes

• poor regulation

• high population density

What contributes to poor health in some cities?

• Excessive green spaces

• Air pollution

• Strict air quality regulations

• Reduced risk of lung cancer

• Increased life expectancy

• Respiratory infection and lung cancer

What do vehicles in cities release that contributes to global warming?

• Oxygen

• Methane
