Sustainable mining practices emphasize:

The correct answer is: d) All of the above

Sustainable mining practices emphasize resource conservation, environmental protection, and community involvement.

• Resource conservation means using mining resources wisely and efficiently, so that they will be available for future generations. This includes using less energy and water, and producing less waste.
• Environmental protection means minimizing the environmental impacts of mining, such as air and water pollution, and land degradation. This includes using best practices to prevent accidents and spills, and to rehabilitate mined land.
• Community involvement means working with local communities to ensure that they benefit from mining, and that the negative impacts of mining are minimized. This includes providing jobs and training, and investing in infrastructure and social services.

Sustainable mining practices are important because they help to ensure that mining can continue to provide economic benefits without damaging the environment or harming communities.
