Why Beachcombing Is Not Really Sustainable
Beach combing may be popular, but it’s not really sustainable. Sand and pebbles are on beaches for a reason (they prevent coastal erosion, and shells in particular house small creatures from hermit crabs to insects. Even ‘crabbing’ can cause harm to injured creatures.
It’s actually illegal to remove sand and pebbles from beaches (also don’t remove driftwood, as again it provides essential habitats for wildlife).
Read how to keep dogs safe by the seaside. Also avoid walking on sand dunes, to avoid disturbing nests and native wildlife.
Natural beach materials provide important functions. Birds peck at broken shells and seaweed, for food and nesting. Harvesting seaweed (without knowing what you are doing) can harm shrimp habitats. Experts just ‘give seaweed a haircut’, without removing the roots.
Keep dogs away from seaweed fronds. They can expand in the stomach, once dry.
What About Sea Glass?
Sea glass is broken bottle litter washed smooth by the waves, to create jewellery. As long as it’s not disturbing habitats, this is okay used to make beautiful jewellery. Your earrings may have been a pirate’s beer bottle from hundreds of years ago. Shiver me timbers!
Why are Beaches Sandy or Pebbly?
It just depends on the beach. Cliff areas have stronger higher waves, so more pebbles. Sandy beaches tend to have gentler waves. The colour of sand depends on what it’s made from (iron oxide makes sand brown, Caribbean coral makes sand white or pink).
