1 Human/Environmental Interaction

2 human/environmental interaction describes how humans use, affect, and are affected by their environment.

3 1. Because of human interventions, certain animals are now extinct (do not exist) in our state.

4 animals like the American bison, wolf, and elk once thrived in West Virginia.

5 Because of these human interventions, these animals are now extinct (do not exist) in the state.

6 Over the years, geography has dictated where people live as well as how they make a living

7 Three major industries in West Virginia were created because unique geographic conditions exist in the state. Coal Chemical Lumber

8 2. The central and southern regions of West Virginia contain valuable supplies of coal.

9 Humans, however, had to alter the natural surroundings somewhat in order to make mining the mineral profitable

10 the lack of roads and navigable streams delayed the region’s development. It was not until the coming of the railroad in the mid- to late 1800s that the area began to grow and become economically successful.

11 Another term for surface mining is “strip mining.”

12 This type of mining actually strips the land, uproots trees, destroys land, and pollutes streams, increasing the potential for erosion and flooding.

13 Today, companies engaged in surface mining must restore the land when they are finished.

14 In some instances, the area is actually left in better condition than before it was mined.

15 The state contained almost limit- less quantities of five of the six elements needed for the production of chemicals.

16 carbon from coal, hydrogen from water, oxygen and nitrogen; from the air, and chlorine from salt brines.

17 Sulfur, the sixth element, was easily obtained from surrounding states.

18 The availability of these elements as well as an abundance of natural gas were major factors in Union Carbide’s decision to locate in the state.

19 4. The Kanawha Valley became known as “the Chemical Valley of the World.”

20 5. Although the chemical industry has brought economic growth and prosperity to the state, it has endangered the environment at times.

21 chemical waste was accidentally or deliberately poured into the state’s rivers and streams, killing wild- life and making some waterways unfit for human use.

22 chemical waste was dumped or buried, causing soil pollution that has left some land unusable.

23 chemical leaks and the machinery used to make the chemicals polluted the air, endangering the lives of those nearby.

24 6. When the first white men came, the entire state was covered with natural forests containing some of the finest hardwoods in the eastern United States.

25 The first trees were cut to provide building material for houses and wood for fuel.

26 they needed wood to make the boats to carry those products to market.

27 7. Lumbering brought other industries to the state; pulp mills and tanneries are two examples.

28 In 1805, stagnant water associated with the tanning industry created the right conditions for the outbreak of a fever that killed a number of people in the eastern panhandle town of Bath.

29 Not all human / environmental interaction has produced bad results.

30 Floodwalls, like the one completed in the year 1996 in Matewan, have been built to protect areas from flooding.

31 floodwalls and dams were built on West Virginia’s smaller rivers
floodwalls and dams were built on West Virginia’s smaller rivers. Some of these dams include those on the Tygart, Bluestone, Elk, and Gauley rivers.

32 The reservoirs created by the dams not only provided a way to control the level of water in the rivers, but also formed lakes that could be used for recreational purposes.
