Urbanization and Environmental Impact

The video discusses the impact of urbanization and deforestation on land and water. Urbanization leads to city growth, urban sprawl, and environmental issues like pollution and habitat loss. Deforestation, including clear-cutting, affects the atmosphere by increasing CO2 levels. Sustainable forestry practices, such as reforestation and prescribed burns, are suggested to mitigate these impacts.

What is urbanization primarily concerned with?

• The growth of rural areas

• The reduction of city populations

• The creation and expansion of cities

• The decline of suburban areas

Which city is highlighted as one of the most populated in the world?

• Tokyo, Japan

• New York, USA

• Mumbai, India

• Dhaka, Bangladesh

What is a major consequence of urban sprawl?

• Improved air quality

• Loss of cropland and wildlife habitats

• Decreased energy consumption

• Increased agricultural land

How has urbanization changed from 1950 to 2030?

• It has increased significantly

• It has decreased significantly

• It has remained the same

• It has fluctuated without a clear trend

What environmental impact is associated with decreased vegetation due to urbanization?

• Decreased temperatures

• Increased oxygen production

• Less air pollution absorption

• More wildlife habitats

Which method can help reduce the impacts of urbanization?

• Expanding urban sprawl

• Building more highways

• Increasing individual car usage

• Using mass transit systems

What is a characteristic of commercial forests?

• Used for timber and paper production

• Preserved as old-growth forests

• Used for parks and wildlife refuges

• Not used for any human activity

What is a disadvantage of clear-cutting forests?

• Increased biodiversity

• Decreased soil erosion

• Increased soil and stream temperatures

• Improved water quality

What is one way to mitigate deforestation?

• Increasing urban sprawl

• Clear-cutting more forests

• Reducing the use of mass transit

• Using integrated pest management

What is the purpose of prescribed burns in sustainable forestry?

• To destroy mature trees

• To reduce the canopy base height

• To increase the occurrence of natural fires

• To control destructive insects and diseases
