Scuba diving is a wonderful way to explore the underwater world and discover its amazing biodiversity. However, not all diving destinations are equally respectful of the marine environment and the local communities. Some places may be overcrowded, overfished, polluted or damaged by irresponsible tourism practices. That’s why it’s important to choose sustainable diving destinations that are committed to preserving the ocean and its inhabitants, as well as providing a high-quality experience for divers.

What is sustainable diving and why does it matter?

Sustainable diving is a form of ecotourism that aims to minimize the negative impact of diving activities on the marine ecosystem and the socio-cultural context of the destination. Sustainable diving operators follow a set of best practices that include:

  • Choosing dive sites that are not overexploited or endangered, and avoiding sensitive areas such as coral spawning grounds or marine protected areas (MPAs).
  • Limiting the number of divers per group and per site, and ensuring that they have adequate training and experience for the dive conditions.
  • Enforcing a no-touch and no-take policy for all marine life, and prohibiting any form of feeding, harassment or disturbance of the animals.
  • Educating divers about the local ecology, culture and conservation issues, and encouraging them to participate in citizen science projects or volunteer activities.
  • Using environmentally friendly equipment and materials, such as reef-safe sunscreen, biodegradable containers, reusable water bottles and natural mask defoggers.
  • Supporting local communities and businesses, and contributing to their social and economic development.
  • Sustainable diving matters because it helps to protect the ocean from further degradation and loss of biodiversity. It also benefits the divers themselves, as they can enjoy a more authentic and rewarding experience, learn new skills and knowledge, and connect with nature and other cultures.

How to be a sustainable diver?

Being a sustainable diver is not only about choosing the right destination, but also about adopting a responsible attitude and behavior before, during and after your dive. Here are some tips to help you be a more sustainable diver:

Do your research: Before booking your dive trip, do some research on the destination, the dive operator and the dive sites. Look for reviews, certifications and awards that indicate their commitment to sustainability. You can also check out websites such as Green Fins or Friend of the Sea that provide guidelines and ratings for sustainable diving operators around the world.

Plan ahead: Plan your dive trip in advance and avoid peak seasons or holidays when the demand and pressure on the dive sites are higher. Also, try to reduce your travel emissions by choosing direct flights, public transportation or carpooling whenever possible.

Pack smart: Pack light and bring only what you need for your dive trip. Avoid single-use plastics and disposable items, such as plastic bags, bottles, straws and cutlery. Instead, opt for reusable or biodegradable alternatives that you can take back home with you or dispose of properly. Also, make sure to use reef-safe sunscreen that does not contain harmful chemicals such as oxybenzone or octinoxate that can damage coral reefs.

Follow the rules: Once you arrive at your destination, follow the rules and instructions of your dive operator and guide. Respect their policies regarding group size, dive duration, depth limit, safety procedures and environmental protection. Listen carefully to their dive briefings and ask questions if you are unsure about anything.

Dive carefully: When diving, be aware of your surroundings and your impact on them. Maintain good buoyancy control and avoid touching, kicking or standing on anything underwater. Keep a safe distance from marine life and do not chase, feed or harass them. If you see any trash or debris underwater, you can collect it carefully if it is safe to do so, or report it to your guide.

Learn more: After your dive, take some time to learn more about what you saw underwater. Ask your guide about the names, behaviors and threats of the marine species you encountered. You can also use apps such as iNaturalist or Seek to identify them yourself. If you want to get more involved in marine conservation, you can join citizen science projects such as Reef Check or Dive Against Debris that collect data on coral reef health or marine debris.
