The main difference between a cultural landscape and a natural heritage site is that cultural landscapes are created by humans, while natural heritage sites are not.

Tourism is not a threat to cultural landscapes, as it can help to raise awareness of and support for these sites.

The best way to protect cultural landscapes is to educate people about their importance, support sustainable tourism, and work with local communities to develop management plans.

UNESCO plays a vital role in protecting cultural landscapes by identifying and designating them as World Heritage Sites, providing financial and technical assistance to countries to help them protect these sites, and working with local communities to develop management plans.

You can help to protect cultural landscapes by visiting them and learning about their importance, supporting organizations that work to protect these sites, and educating others about the importance of cultural landscapes.

When visiting a cultural landscape, it is important to be respectful of the local culture and traditions, stay on designated trails and avoid damaging the landscape, and take your trash with you and leave the site as you found it.

Visiting cultural landscapes can help us to learn about different cultures and traditions, appreciate the beauty and diversity of the natural world, and connect with our own heritage.

Cultural landscapes are a valuable part of our cultural heritage, provide important ecosystem services, and can help to promote sustainable tourism.

Cultural landscapes today face a number of challenges, including climate change, pollution, and tourism.
