• Question 2:The
energy saved by
recycling one
aluminium drinks can
is enough to run a TV
for how long?
A: 30 minutes
B: One hour
C: Three hours
D: Ten hours
The answer is C
Recycling an aluminium can saves up to 95% of the energy
needed to produce the amount of aluminium ore required to
make a new one.

• Question 3:How
much energy does a
energy efficient
washing machine use
compared to an old,
inefficient one?
A: Two thirds less
B: Half as much
C: One third less
The answer is A
Energy efficient dishwaters cut energy use by nearly half
and energy efficient tumble dryers cut it by a third.

A: Human excrement
and pig excrement
• Question 4: Which of
B: Chicken excrement
the following are
and pig excrement
currently being used
C: Chicken excrement
to generate
and human
D: Chicken, pig and
human excrement
The answer is D
Electricity has been generated from human sewage
sludge for decades, and Britain’s first animal dung-fired
power station opened in 2002, using methane from pig,
cow and chicken slurry to generate electricity.

• Question 5: Biodiesel
A: Soya beans
is a natural,
B: Used chip fat
renewable fuel which
C: Carrots
can be used in diesel
D: Oilseed rape
engines – which of
the following can it
NOT be made from?
The answer is C
Biodiesel can be made from most vegetable oils,
including soya bean oil and the oil from oilseed rape
(canola). Some companies manufacture it from used oil
from restaurant fryers. It can be mixed with ordinary diesel.

is a cleaner vehicle
fuel than petrol and
diesel, but electricity is
needed to produce the
hydrogen. If all
Britain’s vehicles were

hydrogen power, how
many more nuclear
power stations would
be needed to generate
the electricity?
A: 10
B: 50

A: 50,000
heat energy stored in
B: 500
the uppermost 10km
C: 5
of the Earth’s crust is
D: 0.5
equivalent to how

The answer is A
The temperature a few metres below ground in the UK is
around 12C. "Ground source heat pumps" are now available
to pump this heat from below ground to warm individual
• Climate change is happening quickly
• It has serious health consequences
• Urgent action has both immediate and long term
benefits for health and the NHS
• Health professionals are trusted and have a duty to
get educated, engaged and set an example by
speaking out and acting on “the 21st century’s most
serious health challenge”
disease burden
• Unsafe water and sanitation, poor hygiene. This environmental hazard is estimated to
kill nearly 1.7 million people annually largely as a result of a range of waterborne
diseases, including diarrhoeal diseases.
• Indoor air pollution. Associated with solid fuel use, mostly in poor countries. Globally,
1.5 million people died from diseases caused by indoor air pollution in the year 2002.
• Urban air pollution. Estimated to kill about 800k every year. Elevated levels of fine
particulates in ambient air – typically emitted by vehicles, industry and energy generation –
are associated with increases in daily and long-term premature mortality due to
cardiopulmonary diseases, acute respiratory infections and cancers.
• Climate change. Causes an estimated 150000 excess deaths annually, as well as
injuries, from more extreme weather events such as heat waves, floods and droughts;
impacts on regional food production; and changed transmission patterns of vector borne
and other infectious diseases.
• Lead exposure. Contributes to both childhood mental retardation and cardiovascular
diseases associated with high blood pressure, together causing a loss of almost 13 million
disability adjusted life years (DALYs - a combined measure of morbidity and premature
mortality) annually, or nearly 1% of the global burden of disease.
Diseases with an
environmental contribution
Diarrhoeal diseases. Some 94% of the 1.8 million annual deaths from diarrhoeal
disease is attributable to environmental causes, particularly unsafe drinking water and
inadequate sanitation.
• Lower respiratory infections. Over 1.5 million deaths annually from lower respiratory
infections (41% of the LRI disease burden) are attributable to environmental factors, largely
associated with exposure to indoor smoke from solid fuels and outdoor (ambient) air
• Vector-borne disease. Over 500000 deaths annually, or 42% of the global disease
burden from malaria, are attributed to modifier able environmental factors such as poorlydesigned irrigation and water systems; poor housing and settlement sitting; deforestation
and ecosystem change/degradation.
• Road traffic injuries. An estimated 467000 deaths from road traffic injuries, or about
40% of the total annual disease burden from traffic injury, is attributable to environmental
factors, e.g. transport and land-use designs that expose pedestrians and cyclists to
excessive risks.
• Unintentional poisonings. Globally it is estimated that 71% of all unintentional
poisonings, which kill about 350000 people annually, are attributable to environmental
factors. In developing countries, such poisonings are strongly associated with poor chemical
management in agro-industries and occupational settings.
