The document discusses different types of ethical tourism such as ecotourism, geotourism, and sustainable tourism that are growing in popularity. While more tourists want non-typical experiences, low-cost travel can have negative environmental impacts. Some criticize eco-tourism as not being truly "green" and instead serving as a marketing concept or form of ego-tourism where tourists seek novelty and social status rather than minimizing their environmental footprint. However, ecotourism can also benefit local economies if done responsibly with reflection on issues like hotel and transportation impacts. The challenges of greenwashing are also addressed, where companies make normal products seem environmentally-friendly through misleading claims.
