What You'll Learn
Reduce carbon emissions and use environmentally-friendly transport
Carbon emissions are a major threat to coral reefs. The increased emissions from burning fossil fuels for energy and heat, as well as deforestation, contribute to the rise in greenhouse gases, which in turn increase ocean temperatures. This warming of the oceans can lead to coral bleaching and even coral death.
To reduce carbon emissions, individuals can make simple changes to their daily routines. Opting for environmentally friendly modes of transportation is one of the most effective ways to lower emissions. Walking, biking, and using public transportation or carpooling are all great ways to reduce your carbon footprint. These methods of travel produce fewer greenhouse gas emissions, which helps to mitigate ocean acidification and temperature rise.
If you do need to drive, consider buying a fuel-efficient vehicle, such as a hybrid or electric car. These vehicles emit fewer pollutants, reducing the amount of carbon released into the atmosphere and, subsequently, the oceans.
In addition to individual efforts, broader changes are also necessary to significantly impact carbon emissions. Civic and political engagement can drive community-wide initiatives that reduce negative impacts on coral reefs. Volunteering, voting, and advocating for sustainable practices can influence companies and institutions to adopt more environmentally conscious practices, reducing carbon emissions on a larger scale.
By combining individual actions with collective efforts, we can effectively reduce carbon emissions and play our part in protecting and preserving the delicate coral reef ecosystems.

Avoid harmful fertilisers, pesticides, and chemicals
The use of fertilisers, pesticides, and chemicals on agricultural land can have a detrimental impact on coral reefs. When it rains, these substances are washed into rivers and streams, eventually flowing out to the reefs. This process increases the growth of phytoplankton, causing algal blooms that block sunlight and reduce coral diversity. Excess nutrients can also make corals more susceptible to bleaching and disease, and inhibit photosynthesis in marine plant species.
To avoid causing harm to coral reefs, individuals can take steps to reduce the use of fertilisers, pesticides, and chemicals. Homeowners can install water catchments or rain gardens and use rain barrels to collect rainwater, preventing it from being diverted into storm drains. This simple action can help to reduce the amount of harmful substances that end up in waterways and oceans.
Another way to reduce the impact of these substances is to adopt more sustainable agricultural practices. Farmers can utilise new technologies that allow them to apply chemicals only where they are needed and improve their irrigation practices. By targeting specific areas, farmers can reduce the amount of excess chemicals that wash off the land and flow into the reefs.
Additionally, individuals can support and advocate for policies that regulate the use of fertilisers, pesticides, and chemicals. By spreading awareness about the harmful effects of these substances on coral reefs, communities can influence local and national decision-making processes to implement stricter controls on their use and disposal.
Finally, it is important to dispose of chemicals properly and avoid flushing them down the drain or pouring them into waterways. Proper disposal ensures that these substances do not end up in the oceans, reducing their impact on coral reefs and other marine ecosystems.

Dispose of trash properly and reduce plastic waste
Plastic pollution is a major threat to coral reefs, with plastic waste ending up in the ocean due to poor waste management practices on land. This includes litter from natural disasters, such as hurricanes and floods, being blown or washed into waterways and oceans. Marine activities, such as fishing, also contribute significantly to plastic pollution.
To reduce plastic waste and protect coral reefs, it is important to dispose of trash properly. This means recycling and reusing items whenever possible, and ensuring that any waste is placed in bins to avoid it being blown or washed away into waterways and oceans. On beaches, it is crucial to leave no trash behind, including cigarette butts, which can be harmful to coral reefs.
At home, individuals can recycle plastic waste and reduce single-use plastic consumption by choosing reusable items. It is also important to check local recycling regulations to ensure proper recycling. Individuals can also support legislation that aims to reduce plastic production and improve waste management practices.
Additionally, individuals can reduce stormwater runoff by installing water catchments or rain gardens, and using rain barrels to collect rainwater. This helps to prevent water pollution and protect water resources, reducing the impact on coral reefs.
By taking these steps to properly dispose of trash and reduce plastic waste, we can help protect coral reefs and the marine biodiversity they support.

Avoid harmful sunscreen and wear sun-protective clothing
The world's coral reefs are suffering due to pollution, coastal development, and warming waters. It is estimated that 14,000 tons of sunscreen are washed into the oceans each year, contributing to the problem. To prevent coral reef pollution, it is essential to avoid sunscreens containing harmful chemicals and opt for sun-protective clothing instead.
Avoid Harmful Sunscreens
Sunscreens often contain chemicals such as oxybenzone, octinoxate, and avobenzone, which are harmful to coral reefs. These chemicals can wash off our bodies and harm the health of coral reefs. Even if you don't swim after applying sunscreen, it can go down drains when you shower, eventually making its way into the ocean. Aerosol versions of sunscreen can also spray large amounts of the product onto the sand, which is then washed into the ocean. Therefore, it is crucial to choose reef-friendly sunscreens that do not contain these harmful chemicals.
Opt for Sun-Protective Clothing
Sun-protective clothing, such as UV-blocking shirts, hats, and sunglasses, can provide effective sun protection while reducing the need for sunscreen. Wearing such clothing can reduce sunscreen usage by up to 90%. Additionally, these items are likely to last longer than a bottle of sunscreen. When visiting coral reefs, consider wearing a stylish hat, sunglasses, and a UV-blocking shirt, such as a rash guard or sun shirt. These clothing items will protect you from sunburn while helping to protect the delicate coral reef ecosystem.
By avoiding harmful sunscreens and choosing sun-protective clothing, you can play a vital role in preventing coral reef pollution and preserving the health of these precious ecosystems.
