CHAPTER 1 INTRODUCTION TO CLEANTECH 1.1 What Is Clean Technology? Environmental technology or "green technology" is the application of the environmental sciences to conserve the natural environment and resources‚ and by curbing the negative impacts of human involvement. Sustainable development is the core of environmental technologies. When applying sustainable development as a solution for environmental issues‚ the solutions need to be socially equitable‚ economically viable‚ and environmentally

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities.

Maladaptive resource management in prior and present societies The situation with the Vikings on Greenland gives a good example of this. Trading walrus ivory with Europeans was an important part of the Economy. The iron was important for the Vikings in fighting against the Inuit people. The Europeans essentially started to trade for elephant ivory instead. There were good growing conditions in some western parts of Greenland in the summers and they lived off animal products‚ i.e. pastoralists. During
