Human Interactions With The Florida Reef

After recently traveling to Florida to explore the Reef, we've come to the conclusion that humans have greatly impacted the Florida Coral Reef. The main problems are as follows:

• Overfishing: 95% of aquarium fish comes from coral reefs.
• Pollution: runoff from land, trash in the ocean, and poor water quality due to the copper found in the ocean. 
• Disease: human pollution and destruction o the biome has created harmful diseases to the organisms such as Aspergillus in sea fans
• Digging of Canals: a serious threat to the marine life's ecosystems

Question:

    What is one way to decrease human impact on the Florida Coral Reef?
