This document discusses environmental challenges and finding balance between human needs and environmental harm. It covers topics like deforestation, biodiversity, pollution, and how activities like farming, industry, and development impact the environment. It also discusses potential solutions like replanting trees that are cut down, hybrid cars that use less gas, and recycling to reduce pollution. The challenges of meeting human needs while minimizing environmental impact are explored.

I. First-Level Activities
A. Creating Farmland
a. As countries grow, what is the one challenge that must be met? The one
challenge that must be met is feeding the people.
B. Environmental Challenges
a. deforestation: or the loss of forest cover in a region._____
b. biodiversity: biodiversity is the richness of different kinds of living
things.
c. People need things to live, but there are often harmful effects on the
environment. Give an example and describe how it is both. One
example s the use of timber for houses, which is a necessity for shelter, but
too much timber being cut down equates to the loss of our forests.
d. Why do you think that many people have changed their lives
drastically, such as vegetarianism, with the industrialization and sprawl? Many
people see that with industrialization has come major consequences such as
pesticides in the water which goes into the fish that are used for food.
C. Finding a Balance
a. Name one example of modern science trying to find a balance between
need and harm. One solution is cutting down of timber, but also replanting once
an area is cleared.
II. Second- and Third-Level Activities
A. Providing Jobs, Reshaping the Environment
a. civil engineering: civil engineering is technology for building structures
that alter the landscape, such as dams, canals, roads, and bridges.
b. How do Hybrid Cars divert some of the natural harm to the
environment?
Hybrid cars use much less gasoline because they are powered by electric
motors as well as gas. Because hybrid cars use gas and electricity, they
produce far less amounts of pollution.
B. Environmental Challenges
a. pollution: pollution is waste that makes the air, soil, or water less clean.
b. Name another form of pollution. Another form of pollution is the
amount of garbage that we make as humans.
c. Is there anything in your life that you can do in order to create less
pollution? What would it take on your part?
