《环境科学》研究了地球环境的物理，化学和生物组成部分，其多样的系统以及它们相互作用的复杂方式。环境科学家使用各种科学和分析技术来测量环境参数，评估环境系统的状态以及预测由于人类活动和气候变化而导致的环境系统的变化。自然和物理系统的行为对于评估人类活动（如农业，工业以及资源提取，加工和使用）的影响至关重要。针对过去，现在和将来的做法和解决方案，研究了污染和污染，全球变暖和生物多样性丧失等环境问题。
Environmental Science examines the physical, chemical, and biological components of the Earth's environment, its diverse systems, and the complex ways in which they interact. Environmental scientists use a variety of scientific and analytical techniques to measure environmental parameters, to evaluate the state of environmental systems, and to project the changes in environmental systems as a result of human activities and climate change. Natural and physical systems behavior is key to evaluating the implications of human activities such as agriculture, industry, and resource extraction, processing, and use. Environmental problems such as contamination and pollution, global warming, and biodiversity loss are studied with regard to past, present, and future practices and solutions.
