Q

Advantages of nuclear power

A
  1. Doesn’t emit carbon dioxide and doesn’t contribute to global warming
  2. The technology is readily available
  3. A large amount of electrical energy is generated in a single plamnt
  4. It is very efficient - 1kg of uranium contains 20 000 times more energy than 1kg of coal.
24
Q

Disadvantages of nuclear power

A
  1. The radioactive waste from nuclear power stations is extremely dangerous and remains so for thoursands of years
  2. Probability of failure - impossible to make it risk-free
  3. Potential terrorist attack target
  4. Energy resource is uranium which is rare and non-renewable
  5. Takes a lot of time to build
25
Q

Advantages of renewables

A
  1. They do not release pollutants such as greenhouse gases or chemicals that contribute to acid rain
  2. They will not run out
  3. Fewer greenhouse gas emissions
26
Q

Disadvantages of renewables

A
  1. Fossil fuel resources are still economically cheaper
  2. The locations are limited by politics
27
Q

Types of renewables

A
  1. Hydroelectric power
  2. Tidal power
  3. Solar energy
  4. Wind power

28
Q

Hydrocarbons

A

chemical compounds consisting of carbon and hydrogen, such as oil and natural gas

29
Q

31
Q

Grey water

A

waste water that has been produced in homes and offices. It may come from sinks, showers, baths, dishwashers, but it does not contain fecal material

32
Q

Nexus

A

the interrelationship, interdependence and interactions between water, food and energy. How changes in one sector impact the other two sectors.

33
Q

A

having access to sufficient, clean, reliable and affordable energy sources for cooling, heating, lighting, communication and productive uses

Having a sufficirnt amount of good-quality food

35
Q

Water security

A

continuing access to safe drinking water and sanitation

36
Q

How can climate change impact nexus?

A

For example in some places (Australia) the agricultural productivity is decreasing meanwhile in other (ig Lithuania could count in the future) it is increasing

37
Q

Circular economy

A

a model of production and consumption, which involves: sharing, leasing, reuising, repairing and recycling existing materials and products as long as possible. this way the life cycle of products is extended

38
Q

What is the aim of circular economy

A

TO make the of the material resources available to us by applying three basic principles: reduce, reuse and recycle.

39
Q

Solid domestic waste

A

a waste type consisting of everyday items that are discarded by the public

40
Q

Ways in dealing with solid domestic waste

A

Recycling, composting, landfill and incineration

41
Q

Problems with incineration

A

Air pollution, toxic ash

42
Q

Recycle

A

use in a different way

43
Q

Reduce

A

use less resource to meet the need

44
Q

Remove

A

eliminate demand altogether

45
Q

Recover

A

Capture some value

46
Q

Thomas Malthus theory

A

Main idea is that there was finite optimum population size IN RELATION to food supply and that any increase in population beyond this point would lead to a decline in the standard of living.

47
Q

Esther Boserup’s theory of population

A

She says that when a need for food arises, someone will find a solution.

48
Q

Emile Durkheim’s theory

A

An increase in population density would lead to a greater division of labour, which would allow greater productivity to be attained

49
Q

Neo-Malthusian theory

A

Same as Malthus theory, but also that contraception would help with the control of population (Malthus itself was against contraception)

50
Q

Optimum population

A

the number of people who, when working with all the available resources, will produce the highest per capita economic return. HIGHEST STANDARD OF LIVING AND QUALITY OF LIFE.

51
Q

Overpopulation

A

occurs when there are too many people, relative to the resources and technology available, to maintain an adequate standard of living. (Bangladesh, Somalia)

52
Q

Underpopulation

A

occurs when there are far more resources in an area that can be used by people living there. (Canada, Australia)

53
Q

The high seas, Antarctica, The atmosphere, The outer space

54
