Beaches are among the most dynamic and ecologically connected systems on Earth. Sand shifts with each tide, organisms migrate with the seasons, and ocean currents connect even the most remote shores to distant ecosystems. Yet these same systems are increasingly stressed by plastic pollution, chemical runoff, and unmanaged human activity.

The good news is that making a difference requires no specialist equipment, advanced training, or deep expertise. Simple habits can slow degradation and help restore resilience. So, let’s take a look!

Treat Plastic Like Invasive Species

Plastics behave in ecosystems much like invasive organisms: they persist, spread, and disrupt ecological functions. Once deposited on beaches, mechanical abrasion from waves and ultraviolet radiation fragment larger debris into microplastics (particles <5 mm) that can mix into sand, be eaten by plankton and animals, and even enter our human bodies.

An estimated 85% of marine plastic originates on land. This means that removing even small fragments before they wash out to sea can prevent them from entering marine food webs. A simple “litter scan” before you leave, collecting both your waste and any stray litter nearby, breaks the cycle of plastic fragmentation at its source.

Choose Reef-Safe Sun Protection

Coral reefs occupy less than 1% of the seafloor yet support roughly 25% of all marine species. Laboratory and field studies have shown that sunscreen chemicals such as oxybenzone and octinoxate can damage coral DNA, hinder larval development, and increase susceptibility to bleaching.

Even if your local coast lacks corals, hydrological connectivity allows contaminants to disperse across watersheds and into reef habitats elsewhere. Switching to mineral-based sunscreens containing non-nano zinc oxide or titanium dioxide, applying them at least 15 minutes before swimming, and combining UV-protective clothing, significantly reduces chemical runoff.

Swap Single-Use for Reusables

A refillable water bottle, washable snack container, and durable tote bag can reduce the need for most disposable packaging during a beach visit. This not only lowers your waste footprint but removes the risk of lightweight packaging blowing into dunes, washing into the sea, or breaking into microplastics.

Over time, more visitors bringing reusables means less litter on the shore, fewer hazards for wildlife, and cleaner beaches for the next person to enjoy.

Bin It Every Time (or Pack It Out)

Though obvious in principle, proper disposal remains far from universal. Global coastal clean-up records list beverage containers, food packaging, bags, bottles, and cigarette butts among the most frequently collected items. Depositing waste in the nearest bin, or carrying it away when no facilities exist, is among the simplest and most effective conservation actions available.

Make Your Mark a Positive One

Every coastal visit leaves a trace. These small, repeatable actions replace erosive traces with restorative ones, helping beaches and the life they support stay resilient long after you’ve gone. By committing to them, you avoid harm and actively leave the beach better than you found it.
