1 Pick 3 of the following words and write anything you know about them on a sticky note (each word should have its own sticky note) Environmental Science natural resource renewable natural resource nonrenewable natural resource sustainable 1

2 In every deliberation, we must consider our impact on the next seven generations. - The Iroqouis Confederacy 2

3 Environmental science is the study of how the natural world works, how the environment affects humans and how humans affect the environment 3

4 Environmental science and the issues that it studies are complex and interdisciplinary. Includes concepts and ideas from multiple fields of study. Decisions have impacts in all these fields of study. Source: Principles of Environmental Science, Cunningham,

5 A Natural resources is any of the natural materials and energy sources provided by nature that can be used for survival or economic gain (profit). 5

6 Renewable resources can be replenished or renewed in a short period of time. Wind energy, timber, water, crops, solar energy, geothermal energy, animals (fish, chicken etc.) 6

7 Nonrenewable natural resources are formed more slowly than they are used (these can be used up). Coal, crude oil (gasoline), minerals, metals, natural gas. 7

8 Coal is a nonrenewable resource. Over time, it will become more difficult and expensive to extract. This graph represents world coal reserves as of It is estimated we have about 250 years of the resource remaining at current rates of use. 8

9 Renewable Resource -sunlight -wind energy -wave energy -fresh water -forest products -farm crops -soil Nonrenewable Resource -crude oil -natural gas -coal -metals 9

10 Sustainability Meeting the human need for natural resources without compromising future generations ability to use them or the environments ability to function indefinitely. 10

11 A great deal of progress has been made since the birth of modern environmentalism, but many debates still rage on. An ecologist named Garrett Hardin wrote an essay called The Tragedy of the Commons, describing the source of environmental problems as a conflict: Short-term interests of individuals versus Long-term interests of civilization and the Earth itself 11

12 A small village consists mostly of farmers that raise and sell sheep at a nearby city. The only place for the sheep to graze is a commons in the center of the village. A commons is an area that belongs to no individual; it is shared by the entire society. Likely outcome: Villagers obtain as many sheep as possible, allow to graze in the commons. Maximize short-term financial gain. 12

13 What if the commons was instead divided into sections that was owned by each villager? Because the land is owned, individuals are much more likely to plan and use it for the long-term. 13

14 The Tragedy of the Commons describes the likeliness of a commons area being exploited for short-term economic gain. Modern examples include the atmosphere and oceans. Norilsk, Russia Source: ecojunk.wordpress.com Zadar, Croatia Source: Agence France-Presse 14

15 The following clip is from a movie about a place where they did not use their resources in a sustainable way. While you re watching look for the answers to the following questions so we can discuss them in small groups after. Name 3 examples you see of things they do differently in Tneedville. Why don t they use resources the same way that you do? 15

16 We will read the directions 1 st I will assign groups of 4 You may not eat the fish until the lab is over 16

17 No talking Raise your hand if you have a question Flip paper over and put pencil down when finished You have 10min 17
