Marine pollution continues to be an environmental issue, despite increased environmental awareness and international conventions on pollution. Over two-thirds of the earth is covered in water, and the consequences of polluted marine ecosystems on human health cannot be ignored. This latest volume of the comprehensive Issues in Environmental Science and Technology series includes chapters from leading marine scientists and discusses pathogens and pollutions in marine ecosystems, along with the impact of toxins released by algal blooms. Looking to the future, the book examines the potential effects of climate change on marine pollution and outlines the challenges facing policy makers.
