Final answer:
Tourism can have both positive and negative impacts on people and the environment. On the positive side, it can generate income, create job opportunities, and promote conservation. However, it can also lead to environmental degradation and pollution.
Step-by-step explanation:
Tourism can have both positive and negative impacts on people and the environment. On the positive side, tourism can generate income and create job opportunities for local communities. It can also promote the conservation of natural resources and cultural heritage through practices like ecotourism. For example, national parks like Yosemite in the United States draw millions of visitors each year, generating revenue for the region while ensuring the preservation of the park's natural beauty.
However, tourism can also have negative effects on the environment. High-traffic tourist sites can experience degradation due to the large number of visitors. Unregulated tourism can lead to environmental pollution, particularly from activities like cruise ship tourism. It is important to manage tourism in a sustainable manner to minimize its negative impacts and protect both people and the environment.
