  1. Air pollution

  2. Water pollution

  3. Deforestation

  4. Increased biodiversity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tourism can have a negative impact on biodiversity through habitat destruction, pollution, and the introduction of invasive species. However, it can also have a positive impact by raising awareness of conservation issues and generating revenue for protected areas.

Multiple choice

How does tourism contribute to water pollution?

  1. Sewage discharge

  2. Industrial wastewater

  3. Agricultural runoff

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tourism can contribute to water pollution through sewage discharge, industrial wastewater, and agricultural runoff. Sewage discharge can contaminate water sources with bacteria and other harmful microorganisms, while industrial wastewater can contain toxic chemicals. Agricultural runoff can also pollute water sources with nutrients, which can lead to algal blooms and other water quality problems.

Multiple choice
