环境科学是对地球的物理，化学和生物过程以及人类与这些过程相互作用的研究。它使用多学科的观点来考虑保护，保存和管理环境的方法。近年来，由于需要为今世后代保护自然和人类环境，环境科学变得越来越重要。现在，诸如气候变化，保护生物多样性，废物和自然资源管理，能源生产以及保护人类健康等环境问题已列在所有政府的议事日程中，从而制定了更加严格的法规和标准。这反过来又增加了对知识渊博和训练有素的环境科学家的需求。
Environmental Science is the study of the physical, chemical and biological processes of the Earth and of human interactions with these processes. It uses a multi-disciplinary perspective to consider approaches to protecting, preserving and managing the environment.Environmental Science has become critically important because of the need to protect the natural and human environment for present and future generations. Environmental issues such as climate change, conserving biodiversity, management of waste and natural resources, production of energy and protecting human health are now high on the agenda of all governments, resulting in stringent regulations and standards, but also new directions for research, focussed on improving the sustainability of all human activities. This in turn has created a greater need for knowledgeable and appropriately trained Environmental Scientists.
