What You'll Learn
Reduce stormwater runoff
Stormwater runoff is a significant contributor to coral pollution. It carries trash, microplastics, and other pollutants such as nitrogen and phosphorus from fertilizers, directly into the ocean. These pollutants can smother corals, block sunlight, and interfere with their ability to feed, grow, and reproduce. To reduce stormwater runoff and protect corals, several measures can be implemented:
Install Water Catchments or Rain Gardens
Homeowners can install water catchments or design and install rain gardens near beach park showers to collect and absorb rainwater, reducing the amount of water that runs off roofs and roads after rainfall. This prevents stormwater from entering storm drains and diverting it from flowing into the ocean.
Use Rain Barrels
Rain barrels can be used to collect rainwater, which can then be utilized for irrigation or other non-potable purposes. This helps reduce the demand for potable water and decreases the amount of stormwater runoff.
Restore Watersheds
Restoring watersheds to their natural state can effectively divert stormwater from flowing into the ocean. This can be achieved by implementing green infrastructure and sustainable practices, such as using native plants to stabilize sediment and natural filters like big planters to capture stormwater runoff.
Reduce Fertilizer Use
Nitrogen and phosphorus from fertilizers are washed into waterways and eventually make their way into the ocean. These nutrients pollute the water and harm coral reefs. Homeowners can reduce stormwater pollution by minimizing fertilizer use or opting for green alternatives that are safer for coral reefs and marine life.
Educate the Community
Spreading awareness about the impacts of stormwater runoff on coral reefs is crucial. Educating family, friends, local schools, and businesses can foster a collective sense of responsibility for protecting coral reefs. This can lead to a more conscious use of fertilizers, proper trash disposal, and support for sustainable practices in the community.

Avoid toxic chemicals
Corals are facing serious threats from toxic chemicals, which can be found in industrial discharges, sunscreens, urban and agricultural runoff, mining activities, and landfill runoff. These chemicals, including metals, organic chemicals, and pesticides, can have detrimental effects on coral reproduction, growth, and physiological processes. Here are some ways to avoid toxic chemicals and protect corals:
Avoid Chemical-Based Sunscreens
Some common sunscreen ingredients, such as oxybenzone and octinoxate, have been identified as toxic to coral reefs. These chemicals can induce bleaching, damage DNA, deform coral young, and even lead to their death. Instead, opt for mineral sunscreens that use non-nano zinc oxide as their active ingredient, as these are considered less harmful to aquatic life. Additionally, wearing UV-protective clothing, such as long-sleeved shirts, rash guards, sun shirts, or pants, can provide sun protection while avoiding the use of potentially harmful sunscreens altogether.
Choose Green Alternatives for Fertilizers and Pesticides
Agricultural and residential fertilizers contain nutrients like nitrogen and phosphorus, which can wash into waterways and oceans. While these nutrients are beneficial for most marine ecosystems, coral reefs thrive in low-nutrient environments. Excess nutrients can lead to excessive algae growth, blocking sunlight and consuming oxygen needed by corals. Therefore, using green alternatives for fertilizers and pesticides that won't harm coral reefs and marine life is essential.
Properly Dispose of Trash and Avoid Single-Use Plastics
Trash, such as plastic bags, bottles, and discarded fishing gear, can make its way into the sea and directly harm corals. Additionally, degraded plastics and microplastics can be consumed by corals and other reef animals, blocking their digestive tracts and introducing toxins. Reducing the use of single-use plastics and properly disposing of trash can help prevent this type of pollution.
Educate Yourself and Others About Coral-Safe Practices
Learn about the potential toxic chemicals that can harm corals and share this knowledge with your community. Educate family, friends, local schools, and businesses about the impact of toxic chemicals on coral reefs. Spread awareness about coral-safe alternatives and encourage others to adopt lifestyle changes that benefit coral health.
By taking these steps to avoid toxic chemicals, we can play a crucial role in protecting corals from watershed pollution and ensuring the health and longevity of these valuable ecosystems.

Improve water quality
Improving water quality is essential to protecting corals from watershed pollution. Here are some ways to achieve that:
Reduce Nutrient Pollution
Excess nutrients, particularly nitrogen and phosphorus, from sources like agricultural and residential fertilizer use, sewage discharges, and animal waste, can fuel the growth of algae and microorganisms that block sunlight and consume oxygen needed by corals. This disrupts the entire ecosystem. To address this, individuals can opt for green alternatives to fertilizers and use only the water they need, reducing wastewater and runoff.
Minimize Stormwater Runoff
Stormwater runoff is a significant source of pollution, carrying trash, microplastics, and pollutants like pesticides and herbicides into waterways and oceans, where they harm coral reefs.
