Read the passage and choose the best answers to the questions below.
Ecotourism is a form of tourism where tourists visit fragile, pristine, and relatively undisturbed natural areas. Its purpose may be to educate the traveller, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights.
However, ecotourism operations occasionally fail to live up to conservation ideals. Even a modest increase in population puts extra pressure on the local environment and necessitates the development of additional infrastructure. The construction of water treatment plants, sanitation facilities, and lodges come with the exploitation of non-renewable energy sources and the utilisation of already limited local resources. The environment may suffer because local communities are unable to meet these infrastructure demands.

A) the local population does not welcome visitors.
B) extra facilities and amenities are required to cope with a population increase.
