This article discusses the three key impacts of marine litter on wildlife and highlights potential solutions to the problems.
What can society do to decrease the damage on wildlife from marine litter? Prevention is the key ! Society should continue in its effort to reduce the amount of waste produced and attempt to reuse and recycle existing items where possible. Furthermore, by supporting beach clean-up events and other environmental debris removal methods, it is hoped that society will be able to assist conservationists in ‘turning the tide on marine litter’ . Because of the cost, impracticalities and time-consuming nature of removing floating debris, there is an urgent need to promote prevention!
