Which of the following is a negative impact of tourism?

Pollution and littering represent a significant negative impact of tourism. As the number of visitors to a destination increases, the amount of waste generated also rises, which can overwhelm local waste management systems. Tourists often leave behind litter, contributing to environmental degradation, and can lead to pollution of natural environments, such as beaches, parks, and wildlife habitats. This not only affects the aesthetic appeal of these areas but can also harm local ecosystems and wildlife, resulting in long-term environmental consequences.

The other options highlight the positive contributions of tourism, such as job creation and economic growth, which can improve local economies. Cultural exchange promotes understanding and appreciation between different cultures, while infrastructure development enhances services and facilities for both tourists and local residents. In contrast, pollution and littering underscore the detrimental side of increased tourist activity, reflecting the challenges that come with managing the environmental impacts of tourism.
