1. Choose suitable cultivation sites: Pearl farming should be conducted in environments with suitable conditions and clean water quality. Avoid farming in ecologically sensitive areas such as coral reefs to prevent damage to the ecosystem.

2. Reduce pollution: Minimize the use of chemicals such as fertilizers, pesticides, and herbicides in the pearl farming process. Control wastewater discharge to prevent the release of harmful substances into surrounding water bodies.

3. Preserve ecosystems: Protect local ecosystems, including marine life and vegetation, in areas where pearl farming is conducted. Maintaining appropriate water quality, temperature, and salinity is crucial for the health of pearl oysters and the quality of pearls.

4. Utilize resources efficiently: Utilize renewable resources and recycle waste as much as possible to reduce energy consumption and resource waste. For example, use solar or wind energy for power and implement a recycling water system to reduce water usage.

5. Community involvement and education: Collaborate with local communities to conduct environmental protection and sustainable development education activities, increasing awareness and understanding of environmental conservation. This can encourage community participation and ensure the sustainability of pearl farming practices.

6. Regulation and policy support: Governments and regulatory agencies should enact relevant policies and regulations to oversee the development of pearl farming, ensuring that it promotes economic development while protecting the environment. Policy support may include setting environmental standards, providing technical support, and rewarding sustainable practices.

By implementing these measures, it is possible to cultivate pearls while safeguarding the natural environment and achieving sustainable development in pearl farming.
