How to protect oceans when you travel

From swimming and snorkelling to watersports and boat trips, oceans can be a source of joy and wonder on holiday.

But if you’re not careful, it's easy to harm the delicate ecosystems that exist below the waves – and contribute to climate change.

"Protecting the oceans is crucial for the health and wellbeing of our planet," says Santi Mier, co-founder of Ocean52, the beverage company that donates 52% of its profits to ocean protection.

"They play a vital role in regulating the Earth's climate by absorbing a significant amount of carbon dioxide, thereby mitigating the impacts of climate change."

These huge bodies of water are home to a vast array of marine species, some of which are yet to be discovered.

"By protecting the ocean, we can ensure the preservation of these invaluable ecosystems and safeguard the biodiversity they harbour," Mier says.

"Moreover, oceans are a source of food and livelihood for millions of people worldwide, and degradation can have severe consequences for coastal communities."

That's why it's important to make sure you minimise your impact in terms of plastic, pollution and sealife.

To mark World Ocean Day (June 8), here's how to protect oceans when you’re on holiday…

Use reef-safe sunscreen

"In 2018, Hawaii became the first nation to ban suncreams containing oxybenzone and octinoxate after scientists found these chemicals were harmful to ocean fauna," says Jo Royle, founder and CEO of Common Seas, a social enterprise tackling plastic pollution.

While many sunblocks are labelled ‘reef-safe’ or ‘reef-friendly’, these terms aren't regulated, so it's important to check the ingredients list.

Royle says: "Look for suncreams that contain active ingredients: zinc oxide and titanium. These physical UVS and UVB filters shield the skin from absorbing any rays, whilst keeping ocean life happy."

Don't touch the coral

As well as being affected by chemicals in the water, coral is susceptible to physical stress.

"Coral reefs are beautiful and it may be tempting to get close and interact with them for a closer look, but did you know they’re actually small creatures in the same family as anemones and jellyfish?" Royle says.

"To protect this delicate ecosystem already under threat, be careful not to touch or walk on the ocean floor."

Bring refillable containers

When taking drinks or a picnic to the beach, opt for reusable containers and don't leave any rubbish behind.

"Every year 4.2 million tonnes of plastic waste is produced by the tourism industry, and 85% of all marine litter is accounted for by plastic waste," says Royle.

Rob Greenfield, content creator at Earthtopia, one of TikTok's largest eco-communities, advises: "Fill a reusable bottle with tap water (if safe to do so) and bring it to the beach along with reusable cutlery. If you’re worried about tap water quality, try a reusable bottle with a filter in it."

Jenny Wassenaar, chief sustainability officer at Trivium Packaging, recommends taking a reusable metal water bottle.

"If made out of metal, the vessel can also be infinitely recycled, as opposed to plastic that very often only has a life cycle of just a handful of material loops."

Bin your butts

"If you smoke, make sure you bring a metal tin to the beach to put your cigarette butts in," says Greenfield.

"They can take up to 10 years to break down and release nasty chemicals like arsenic in the process."

Don't book a cruise

"For sustainable sea-lovers looking for their next holiday, it's best to look past cruise ships," Royle says.

These floating behemoths damage the oceans in numerous ways: "Contributing to ocean acidification; dumping raw sewage and grey water containing harmful chemicals from sinks, laundries and showers into the ocean."

Choose sustainable fish

As with buying fish to eat at home, it's best to avoid species where populations are low or where fishing practices harm other fish.

"When eating out or cooking, check where your fish is from by asking the waiter or fishmonger," says Greenfield, who recommends checking the Marine Conservation Society's Good Fish Guide.

"Make sure you only buy local line-caught fish to avoid eating any fish that has been caught using trawlers, which is unsustainable and can kill other marine animals as bycatch, or shipped over a massive distance."
