Conservation refers to the careful and controlled use of natural resources for the purpose of extending the time they are available as well as retaining biodiversity. This book explores aspects of conservation, particularly the conservation of plant life upon which ecosystems are built

The oceans contain 97% of the Earth's water and cover 71% of its surface. Sea level depends on global climate, and the Earth's climate is changing. We have reached the point where the oceans can no longer absorb the waste we throw into it. We offer a global scientific approach for middle school students by covering critical factors including; what and where salt water is and how human activity and climate change is affecting the purity of the oceans and the quantity and health of its sea life. All concepts and vocabulary are presented in a way that makes it accessible to students and easier t

This major textbook provides a broad coverage of the ecological foundations of marine conservation, including the rationale, importance and practicalities of various approaches to marine conservation and management. The scope of the book encompasses an understanding of the elements of marine biodiversity - from global to local levels - threats to marine biodiversity, and the structure and function of marine environments as related to conservation issues. The authors describe the potential approaches, initiatives and various options for conservation, from the genetic to the species, community and ecosystem levels in marine environments. They explore methods for identifying the units of conservation, and the development of defensible frameworks for marine conservation. They describe planning of ecologically integrated conservation strategies, including decision-making on size, boundaries, numbers and connectivity of protected area networks. The book also addresses relationships between fisheries and biodiversity, novel methods for conservation planning in the coastal zone and the evaluation of conservation initiatives.
