Green means happiness in Hainan

National surveys often show that people from the tropical island province of Hainan are high on the happiness scale. A healthy ecology and green-themed sustainable practices are the key elements cited.

"I travel around the world but Hainan is always home," one survey respondent wrote. The reasons the respondent gave for choosing Hainan as a permanent place of residence were many, but the island's quality ecological resources were at the top of the list.

Hainan has taken several proactive steps to preserve its lush rain forests, verdant mountains and pristine sandy beaches - both to protect ecological diversity and to make sure the province's proud reputation as a tourist haven remains unblemished.
