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?
Consume More
Resources
Thermal
Toxic Waste
Water
Solid Waste
Disposal
Air
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:
1)Oil
2)Coal
3)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.
**Nuclear power
plants do not pollute
the air or water with
toxic chemicals
Help Generate
Electricity
Problems:
1)Cause thermal pollution of waterways.
2)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
1)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.
Date: May 17th, 2017- period 5
Aim # 78: How has technology and industrialization
negatively impacted our environment?
Do Now:
1) What is eutrophication? What causes it? How does
it affect aquatic ecosystems?
2) What is DDT? Which level of the food chain would
have the greatest concentration? What is this called?
HW:
1)RRB pages 9-18 due Friday
2)Castle Learning (QUIZ #3) due next MONDAY
3)Human Impact Test next Wednesday
4)Ecology Test Corrections due next Thursday

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!
1) What is technology? How has it affected the
human population?
2) What causes acid rain?
3) What is smog?
4) What is thermal pollution? Why is this a
problem?
5) What is DDT? In which trophic level would there
be the greatest concentrations of DDT?
6) What is eutrophication?
