Environment: the total of our surroundings
• All the things around us with which we interact: Biotic vs. Abiotic
• Living things
• Animals, plants, forests, fungi, etc. • Nonliving things • Continents, oceans, clouds, soil, rocks • Our built environment

按物质形态 按成因分 按主体分 人类环境 自然环境
水环境
大气环境
土壤环境
生物环境 环境 宇宙环境 地球环境 区域环境 特定空间环境
人工环境
按范围大小分
4 、环境的特性
(1) 整体性
人与自然环境是一个整体，地球的任一 部分或任一系统，都是人类环境的组成部分， 各部分之间存在着相互依存和互相制约的关 系。 所以环境的影响是整体的，无国界的。
4 、环境的特性 (5) 持续反应性
环境对人类的影响是可持续的，不仅对当 代人，而且对子孙后代有着深远地影响。 事例：日本水俣病事件 放射性污染等
4 、环境的特性 (6) 放大性
某一局部环境状况较小、不引人注目的 环境污染与破坏，经过系统的协同放大后其 危害性明显放大。从一定意义上讲，放大性
也体现了第一条——整体性。
4 、环境的特性
(3) 不可逆性
含义：环境一旦遭到破坏，只能实现局部
恢复，但不能彻底回到原来的状态。 污染容易，治理困难。 事例： 泰晤士河、莱茵河、中国淮河的污染 和治理等。
4 、环境的特性
(4) 潜在性
除突发性自然灾害和人为污染可直观其后 果，一般情况下环境的变化对人类的影响需 要较长时间才能显现出来。 事例：日本水俣病事件 农药DDT的影响
(2) 有限性
环境本底值
环境在未受到人类干扰的情况下，环境
中化学元素及物质和能量分布的正常值。 环境容量 在人类生存和自然环境不致受害的前提 下，环境可能容纳污染的最大负荷量。
(2) 有限性
环境自净作用
污染物进入环境后，将引起一系列物理

Water pollution is the contamination of water bodies such as lakes, rivers, oceans, lagoons, and groundwater. All water pollution affects organisms and plants that live in these bodies of water and in almost all cases the effect is damaging either to individual species and populations but also to the natural biological communities. It occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful constituents.

Pollutant
• If the concentration of a substance already present in nature or a new substance increases to undesirable proportion by human action so that it spoils the environment and lowers the quality of life or effects health • CO, SO2, NO2, Dust, Pollen etc. • Compounds of metals like Zn, Hg, Cd, As etc.
Global, regional & local, pollutants
• A global pollutant refers to a pollutant whose damage is determined by its concentration in the upper atmosphere • CO2 is often cited as a contributor to the greenhouse effect • Chloroflourocarbon emissions are linked to ozone depletion
Lithosphere
• Outer mantle of solid earth • Mineral occurring in earth crust & soil • Soil -most important component
Biosphere
The biosphere is made up of the parts of Earth where life exists—all ecosystems. • Realm of living organism & their interaction with environment • Biological world intimately linked with energy flow in environment

There is no doubt that developed countries are the largest group of timber consumption. Of course, part of the wood consumption in developing countries should not be ignored.
II. Greenhouse effect
There is no doubt global warming is a fact. Global warming is very serious consequences, such as glaciers melt, sea level rise, desertification, to the ecological system and the serious impact on agricultural production.
2、situation
The development of mankind itself has long been confined to areas of economic development, and economic development of the natural environment and natural resources to rely on the support of the productive forces, and inevitably the quality of the environment have a negative impact. Half of the 20th century, the development of humanity has been a global threat to the environment for the survival of human beings.

CHAPTER ONE Environmental Interrelationships
OBJECTIVES After reading this chapter, you should be able to: Understand why environmental problems are complex and interrelated. Realize that environmental problems involve social, political, and economic issues, not just scientific issues. Understand that acceptable solutions to environmental problems are not often easy to achieve. Understand that all organisms have an impact on their surroundings. Understand what is meant by an ecosystem approach to environmental problem solving. Recognize that different geographic regions have somewhat different environmental problems, but the process for resolving them is the same and involves compromise.
Environmental science is intended as a text for a onesemester, introductory course for students with a wide variety of career goals. They will find it interesting and informative. The central theme is interrelatedness . No text of this nature can cover all issues in depth. What we have done is to identify major issues and give appropriate examples that illustrate the complex interaction that are characteristic of all environmental problems.

1 The Nature of Environmental Science
Environment: the surrounding conditions that affect people and other organism. In a broader definition, environment is everything that affects an organism during its lifetime. 环境：与某一中心事物有关的周围事物，就是这个中心事物的环境。 Environmental Science: is an interdisciplinary area of study that includes both applied and theoretical aspects of human impact on the world.
Introduction of Environmental Science
A Study of Interrelationships
1
Environmental issue and it’s solutions
Environmental science is an interdisciplinary field. Because environmental disharmonies occur as a result of the interaction between humans and the natural world, we must include both when seeking solutions to environmental problems. It is important to have a historical perspective, appreciate economic and political realities, recognize the role of different social experiences and ethical backgrounds ,and integrate these with the science that describes the natural world and how we affect it.
