Resource managment Flashcards
What are the consequences of eating less food calories
Famine result in malnutrition illnesses and starvation which can cause weakness and difficulty to work
implications of eating too much calories
excessive weight gain causing difficulty to work and cardiovascular disease
Function of water
absorb nutrients and get rid of waste
How much water should you consume a day
1.6 - 2 litres
How is water used in drier countries
irrigation enabling crops to grow
What impact can water insecurity have on health
water-borne diseases such as cholera due to contaminated water source.
What do drought cause
crop failure reducing yield and increases food insecurity
What are uses of energy
heats homes, used to cook food and transport
how does energy insecurity have an impact on food production
demand large amounts of power to power machinery and farmers rely on fossil fuels
why is importing food beneficial for the UK
produce of seasonal food all year round and access to exotic foods that cant be grown in UK climate
why is importing food bad for the UK
greater food miles hence more co2 emissions and climate change occur
farmers may be exploited and underpaid
What is agribusiness
using intensive farming strategies and modern technology to improve crop yield
why is the consumption of water increasing
the population is increasing and each person is using around 150 litres of water
explain desalination
salt water converted into fresh water increasing volume of fresh water available however require energy and cost.
significance of water transfer schemes
reservoirs around UK to supply cities with water reducing water inequality
What is the aim of Kielder water
it holds up to 200 billion gallons of water during periods of high rainfall so it can be transferred to cities in south that suffer from water insecurity
what are benefits of water transfer schemes
surplus water can be used in insecure places
rural areas have more space to store reserviors
why are water transfer schemes bad
very expensive
habitats destroyed as fishes cannot migrate up river.
concrete used can release large amounts of co2
What can people at home do to maintain water levels
conserve water by reducing water wastage and turning off tap whilst brushing teeth .
What is grey water
water that isn’t clean but doesn’t have sewage in it
why is grey water beneficial
can be used to reduce clean water use
used in toilets and irrigating crops
what do the environment agency do
regulate water sports stop them in reservoirs to prevent water pollution
filter and purify water
what percentage of UK energy is generated by fossilfuels
40%
what percentage of UK energy is renewable
20%
Why is energy exploitation economically bad
Cost a-lot of money - building power-station then maintaining it and running cost
Why is energy exploitation environmentally bad
fossil fuels create emissions and noise pollution
uranium is radioactive
negative impact of agribusiness
increase use of chemical fertilisers - bad for enviroment
positives of agribusiness
more food security and cheaper prices providing jobs for skill workers
