1. CHAPTER 1 Environmental Problems, Their Causes, and Sustainability

2. Core Case Study: A Vision of a More _______World in 2060
A transition in human _______ toward the environment, and a shift in _______, can lead to a much better future for the planet in _______.
___________: the capacity of the earth’s natural systems and human cultural systems to _______, flourish, and adapt into the very _________ future

3. Figure 1.1: These parents—like Emily and Michael in our fictional vision of a possible world in 2060—are teaching their children about some of the world’s environmental problems (left) and helping them to enjoy the wonders of nature (right). Their goal is to teach their children to care for the earth in hopes of passing on a better world to future generations.

4. 1-1 What Are _______ Principles of Sustainability?
Concept 1-1A Nature has sustained itself for billions of years by using ______ energy, biodiversity, and ________ cycling.
Concept 1-1B Our _____ and _______ depend on energy from the sun and on natural resources and natural services (natural capital) provided by the _______.

5. Environmental Science Is a Study of Connections in Nature (1)
Everything around us
“The environment is __________ that isn’t ____.“
________________: interdisciplinary science connecting information and ideas from
_____________: ecology, biology, geology, chemistry…
_____________: geography, politics, economics
____________: ethics, philosophy

6. Environmental Science Is a Study of Connections in Nature (2)
How nature works
How the environment affects us
How we affect the environment
How to deal with environmental problems
How to live more sustainably

7. Nature’s Survival Strategies Follow Three Principles of Sustainability
Reliance on ______________
The sun provides warmth and fuels photosynthesis
_______________
Astounding variety and adaptability of natural systems and species
________________
Circulation of chemicals from the environment to organisms and then back to the environment
Also called ____________________

8. From Simple Cell to Homo Sapiens
First simple cells appear (about 3.5 billion years ago)
First multicellular life appears (about 1 billion years ago)
First major land plants appear (about 475 million years ago)
Dinosaurs disappear (about 65 million
years ago)
Figure 1.2: Here, the span of Homo sapiens sapiens’ time on earth is compared with that of all life beginning about 3.5 billion years ago. If the length of this time line were 1 kilometer (0.6 miles), humanity’s time on earth would occupy roughly the last 3 one-hundredths of a millimeter. That is less than the diameter of a hair on your head—compared with 1 kilometer of time.
Homo sapiens arrives (about 200,000 years ago)

9. Three Principles of Sustainability
____________
Figure 1.3: Three principles of sustainability.
We derive these three interconnected principles of sustainability from learning how nature has sustained a huge variety of life on the earth for at least 3.5 billion years, despite drastic changes in environmental conditions (Concept 1-1a).

10. Sustainability Has Certain Key Components
______________: supported by solar capital
Natural __________: useful materials and energy in nature
Natural __________: important nature ____________ such as renewal of air, water, and soil
Humans _________ natural capital
Scientific solutions needed for environmental sustainability

11. Natural Capital = Natural Resources + Natural Services
Figure 1.4: These key natural resources (blue) and natural services (orange) support and sustain the earth’s life and human economies (Concept 1-1a).
