Tourism puts enormous stress on local land use, and can lead to soil erosion, increased pollution, natural habitat loss, and more pressure on endangered species.

The main impact of tourism is a multifaceted "triple bottom line" affecting the economy, environment, and local culture. Economically, tourism is a massive engine for job creation and infrastructure development, often accounting for a significant portion of a country's GDP. However, it can also lead to "over-dependency" and inflation in local prices. Environmentally, tourism brings both the risk of increased carbon emissions and habitat disruption, but also the benefit of funding conservation efforts and raising global awareness for protected areas. Socially and culturally, it facilitates "global exchange" and can help preserve traditional crafts and music by creating a market for them. On the negative side, "over-tourism" can lead to the "commodification" of culture and friction with host communities. In 2026, the global focus has shifted heavily toward sustainable and regenerative tourism, aiming to ensure that the positive economic gains do not come at the expense of the destination's ecological or social integrity.
