One of the main principles of green tourism is to protect and respect the cultural and social integrity of the host community.
This means visitors should value and maintain the traditional customs, heritage, and lifestyles of the local people.
Respecting socio-cultural authenticity helps preserve unique cultural identities and prevents the negative effects of mass tourism.
It also encourages meaningful interaction between tourists and local communities, creating mutual understanding and appreciation.
Options like avoiding gatherings, driving smart, or using off buttons are general eco-friendly practices,
but they do not specifically relate to the principle of respecting cultural authenticity in green tourism.
Therefore, the best answer here is to respect socio-cultural authenticity of host country.
