Question 1

What is Biocapacity

Answer 1

Land and water to supply resources for humanity

Question 2

What is ecological footprint

Answer 2

The amount of land required by a group/person to full fill all their resources and assimilate their waste.

Question 3

What is energy security?

Answer 3

Having access to clean,reliable and affordable energy for cooking, heating, lighting etc.

Question 4

What is water security?

Answer 4

Having access to clean and safe drinking water and sanitation

Question 5

What is food security?

Answer 5

Having access to safe and nutritious food, meatiness the dietary needs and food preferences for an active and healthy life.

Question 6

What is nexus

Answer 6

The interactions/connections between food, water and energy

Question 7

What is virtual/ embedded water

Answer 7

Transferring water from one country to anotehr via exports

Question 8

What is the issue with a growin population and population of rich people?

Answer 8

An increase in consumption of recourses

Question 9

What does eating meat do to an ecological footprint?

Answer 9

Increase it, different from only relying on vegetables

Question 10

How can the ecological footprint be reduced?

Answer 10

• vegetarian diets
• recycling/ reusing resources
• reducing amount of pollution
• transporting waste to other countries’
• reducing amounts of recources

Question 11

How is the ecological footprint increased?

Answer 11

• meat diets
• large consumption per household
• Relying on fossil fuels
• high levels of imported products

Question 12

Why do HIC’s have a greater ecological footprint than LIC’s?

Answer 12

• Greater infrastructure
• can afford more food
• eat more meat

Question 13

How is water distributed around the world?

Answer 13

unevenly

Question 14

What is teh relationship between water availability and consumption

Answer 14

Increased consumption means an increase in water scarcity. There are no major differences of how water is used in HICs and LIC’s

Question 15

All of what factors increase pressure on water?

Answer 15

• tourism (water parks eg)
• urbanisation (invest in sanitation for water)
• growing middle class (showers, gardening)
• climate change(droughts, floods)

Question 16

How to increase crop yield

Answer 16

• using genetically modified dna from other organisms
• irrigation
• more land for crops

Question 17

How does urbanisation strain food consumption?

Answer 17

Strain on meat due to fast food

Question 18

Which type of countries need more energy?

Answer 18

NIC’s as they are currently industrialising

Question 19

Difference between renewable and non- renewable energy

Answer 19

Renewable energy doesnt reduce any natural capital while non-renewable does.

Renewable (hydroelectric, wind, solar)
Non-renewable (fossil fuels

Question 20

Why is mostly non-renewable energy used?

Answer 20

It is cheaper, no need for refining, technology is already developed.

Question 21

Advantages of nuclear power

Answer 21

• doesnt emit CO2, doesnt contribute to global warming
• technology is developed and available
• creates large amounts of energy in small plant
• very efficient compared to fossil fuels

Question 22

Disadvantages of nuclear power

Answer 22

• creates radioactive waste, harmful
• dangerous, never 100% sure of irs reliability
• the more nuclear powers, the higher risk of failure: explosion
• targets for terrorists
• energy source is uranium which is scarce
• takes 20-30 years to build
  Chernobyl eg.

Question 23

Disadvantages for renewable energy

Answer 23

Location site is minimised/ availability minimal
- not visually appealing

Question 24

Advantages of renewable energy

Answer 24

• they will NOT run out
• do not contribute to climate change/ acid rain

Question 25

WHat is Hydroelectiv power

Answer 25

Turbines switched on and off in dams, producing energy

Question 26

Advantages and disadvantages for HEP

Answer 26

A:
- cheap to run
- fit by dams
- can be turned on and off

DA:
- cause flooding downstream
-Accelerate river velocity
- cause increased erosion in river
- dams restrict transport of sediments

Question 27

What is biofuel energy

Answer 27

Burning of biomass-> ethanol-> fuel

Question 28

How do wind turbines work?

Answer 28

They are driven by occurring winds (turbines)
Rotational energy is put into a generator -> electricity

IF there is no wind, no energy is produced

Question 29

Why is recycling important?

Answer 29

Saves scarce materials, reduces pollution

Question 30

What is the issue with E-waste

Answer 30

It gets illegally shipped to developing countries

Question 31

Explain how E- waste effects the area it is shipped to

Answer 31

Once in a landfill, assimilated Ewaste containing toxic substances such as lead and emrcury seep into the environment (land, water etc) and contaminate them. The workers suffer from illnesses and infection- short life expectancy.

Question 32

Why is an increase in E-waste occurring ?

Answer 32

There is so much innovation and improvement of technology

Question 33

What is overpopulation

Answer 33

When the population exceeds the amount of recources available

Question 34

What is underpopulation?

Answer 34

The the amount of recources aren’t able to be used up by the population

Question 35

Formula for standard of living

Answer 35

(Natural resources x technology)
/ population

Question 36

What is recources stewardship

Answer 36

A concept suggesting that we can use recources in a way to be available for future generations aswell

SOCIAL EQUITY over the recources

Question 37

What is a circular economy?

Answer 37

• preserving natural capital by balancing recources flows
• optimize resource yields by circulating products (recycling)
• eliminating pollution and climate change
