1. Environmental Protection: Measures are taken to protect coral reefs and marine ecosystems in pearl farming areas. This may include restrictions on fishing activities, prohibition of pollutant discharge, and establishment of marine protected areas.

2. Biodiversity Conservation: Pearl farms typically implement measures to conserve local marine biodiversity, such as avoiding large-scale pearl farming near coral reefs to reduce impacts on local ecosystems.

3. Technological Improvements: Sustainable pearl farming practices often utilize advanced technologies and methods to minimize the use of energy and water resources, and reduce disturbances to the surrounding environment.

4. Regulation and Compliance: Governments and regulatory bodies may enact regulations and standards to ensure that pearl farming activities adhere to principles of environmental protection and sustainable development.

5. Community Engagement: Sustainable pearl farming practices often actively engage with local communities to promote community participation and co-management, ensuring that pearl farming activities have positive impacts on local economies and social development.

Overall, sustainable pearl farming practices aim to achieve environmental, economic, and social sustainability through the protection of ecosystems, maintenance of biodiversity, improvement of farming techniques, and strengthened regulation.
