‘Shell Clash’ refers to the competitive and potentially destructive interaction between shells in marine habitats. Shorelines worldwide are witnessing a sharp increase in shell clash due to a rise in anthropogenic debris. Though seeming insignificant, this escalation creates an adverse effect on the welfare of multiple marine species, disrupting their natural habitats and causing a ripple in the ecosystem. It is critical to observe and acknowledge the buried impact of such subtle, yet serious environmental issues. Addressing this ‘Shell Clash’ is a crucial stride towards preserving our marine life and, in turn, our planet.
