The main objective of this book is to provide a comprehensive understanding of environmental law, covering its foundations, policies and contemporary challenges. Through an interdisciplinary approach, we seek not only to explain the legal bases of environmental law, but also to analyze how these are implemented and dealt with in practice. This book is designed for both students and practitioners of law as well as for anyone interested in environmental protection.Environmental law is a vital discipline in the protection and preservation of our planet. With the increasing impact of human activity on ecosystems, climate change and biodiversity, it has become essential to have a robust legal framework to regulate human activities and promote sustainable development. Environmental law not only protects natural resources, but also ensures that future generations can enjoy a healthy and balanced environment.
