Aim #78: How has technology & industrialization negatively impacted the environment?

1) What is Industrialization? Industrialization is the development of an economy in which machines produce many of the products people use.

2) What is Technology? The use of scientific knowledge & technical processes to meet human needs.

3) What have been the effects of Industrialization & Technology on human population? They have allowed for an enormous surge in population growth? a) Why? These machines & technologies have been able to meet the needs of more & more people.

4) What are the effects of these advances? Solid Waste Disposal Thermal Consume More Resources Air Toxic Waste Water Pollution

5) Consumption of More Resources: Industrialization increases the demand for energy, water, and other resources including fossil & nuclear fuels. a) What are the 3 main fossil fuels: Oil Coal Natural Gas b) What kind of resources are fossil fuels? Non-Renewable Help Generate Electricity

6) What is Nuclear Fuel? Nuclear fuel is an energy source that results from the splitting of atoms. Help Generate Electricity **Nuclear power plants do not pollute the air or water with toxic chemicals Problems: Cause thermal pollution of waterways. Difficult to safely dispose of nuclear (radioactive) wastes .

7) Consumption of Water: + Most factories use a lot of water. This can lead to serious consequences for the native plants and the consumers that depend on them for food.

8) Types of Pollution: Water Sewage, wastes from homes & factories, animal wastes from farms, & fertilizers can be disposed of in rivers, lakes, & oceans.

9) What are the effects of sewage & animal wastes in aquatic systems? Eutrophication Sewage & animal wastes act as fertilizer & increase the growth of aquatic producers (very rapid). 2) Produce a lot of oxygen during the day (photosynthesis) and none at night. 3) Use all the oxygen at night. 4) Other organisms suffocate.

10) Pollution: Toxic Wastes Toxic (poisonous) wastes can cause environmental problems because when they are disposed of they can collect in the cells of organisms. Mercury is a toxin that can be found in fish

11) Biological Magnification The concentration of toxic substances (DDT) as you move through the food chain increases.

12) Pollution: Thermal (Heat) Some power plants & industries use water to cool their machines. The warmed water is then released into a river or lake. The warm water cannot hold as much oxygen as cold water and some species may suffocate.

13) Pollution: Air + The burning of fossil fuels that were formed from the remains of organisms millions of years ago contribute to air pollution. CO2, SO2, NO2 + S = Sulfur N = Nitrogen

14) Effects of Air Pollution: Acid Rain Due to burning of fossil fuels SO2 & NO2 Rain mixes with gases in air Burning of trees and destruction of pond ecosystems

14) Effects of Air Pollution: Smog Smog is a kind of air pollution that results when certain pollutants react with sunlight.

15) Pollution: Solid Waste A new increased demand for disposable products has led to solid waste problems.

16) How much trash does Manhasset produce each year? The average U.S. citizen produces 4.5 pounds of trash each day. How many pounds of trash does Manhasset produce in one year? Manhasset Population = 8,080 Answer = 13,271,400pounds

Let’s Review! What is technology? How has it affected the human population? What causes acid rain? What is smog? What is thermal pollution? Why is this a problem? What is DDT? In which trophic level would there be the greatest concentrations of DDT? What is eutrophication?
