Question 16

Impact of Tourism: Regulation

Answer 16

Many countries have implemented regulations to manage tourism’s impact on the environment, such as limiting visitor numbers in sensitive areas.

Question 17

Land Degradation: Desertification

Answer 17

The process of fertile land transforming into desert, often due to deforestation, overgrazing, and poor agricultural practices, is a significant issue in arid and semi-arid regions.

Question 18

Land Degradation: Soil Erosion

Answer 18

Land degradation often leads to soil erosion, where the topsoil is worn away, reducing the land’s agricultural productivity.

Question 19

Land Degradation: Deforestation

Answer 19

The clearing of forests for agriculture or development is a major cause of land degradation and loss of biodiversity.

Question 20

Land Degradation: Sustainable Agriculture

Answer 20

Techniques such as crop rotation, agroforestry, and conservation tillage can help prevent land degradation and restore degraded lands.

Question 21

Land Degradation: Land Restoration

Answer 21

Efforts to restore degraded lands include reforestation, the establishment of conservation areas, and soil conservation measures.

Question 22

Pollution: Air Pollution

Answer 22

Caused by emissions from vehicles, industries, and agriculture, air pollution contributes to respiratory diseases and climate change.

Question 23

Pollution: Water Pollution

Answer 23

Contaminants such as industrial waste, sewage, and agricultural runoff pollute water bodies, harming aquatic life and human health.

Question 24

Pollution: Soil Pollution

Answer 24

Chemicals from pesticides, fertilizers, and industrial waste contaminate soils, reducing agricultural productivity and posing health risks.

Question 25

Pollution: Noise Pollution

Answer 25

Urbanization and industrialization have led to increased noise levels, affecting both human health and wildlife.

Question 26

Pollution: Plastic Pollution

Answer 26

The accumulation of plastic waste in the environment, particularly in oceans, poses significant threats to marine life and ecosystems.

Question 27

The Sea and Marine Environments: Overfishing

Answer 27

Over-exploitation of fish stocks threatens marine biodiversity and food security for communities that rely on fishing.

Question 28

The Sea and Marine Environments: Coral Reefs

Answer 28

Coral reefs, which are vital to marine biodiversity, are increasingly threatened by climate change, pollution, and destructive fishing practices.

Question 29

The Sea and Marine Environments: Marine Pollution

Answer 29

Pollution, especially from plastic waste and oil spills, severely impacts marine life and ecosystems.

Question 30

The Sea and Marine Environments: Marine Protected Areas

Answer 30

These are designated regions where human activity is restricted to conserve marine biodiversity and ecosystems.

Question 31

The Sea and Marine Environments: Ocean Acidification

Answer 31

The absorption of excess atmospheric CO2 by oceans leads to acidification, affecting marine organisms, especially those with calcium carbonate shells or skeletons.

Question 32

Urbanization: Urban Sprawl

Answer 32

The uncontrolled expansion of urban areas into surrounding natural environments leads to habitat destruction and increased pollution.

Question 33

Urbanization: Infrastructure Development

Answer 33

Urbanization requires extensive infrastructure, such as roads and buildings, which can disrupt natural ecosystems and contribute to environmental degradation.

Question 34

Urbanization: Heat Islands

Answer 34

Urban areas tend to be warmer than their rural surroundings due to the concentration of buildings and human activities, a phenomenon known as the urban heat island effect.

Question 35

Urbanization: Sustainable Urban Planning

Answer 35

Incorporating green spaces, efficient public transport, and sustainable building practices helps mitigate the environmental impact of urbanization.

Question 36

Urbanization: Waste Management

Answer 36

Recycling programs help reduce the amount of waste sent to landfills, conserving resources and reducing environmental impact.

Question 39

Waste Management: Composting

Answer 39

Organic waste can be composted to produce nutrient-rich soil, reducing the need for chemical fertilizers and decreasing landfill waste.

Question 40

Waste Management: Waste-to-Energy

Answer 40

Some waste can be converted into energy through processes like incineration or anaerobic digestion, providing an alternative to landfilling.

Question 41
