Paper 2 resources in the UK Flashcards
how has demand for food in UK changed
before supermarkets most food was seasonal and from UK or preserved
Now food is from around the world even seasonal fruit is imported as grown cheaper
how has increase in demand for nonseasonal products had an impact on LICs in a negative way (3)
less land available for locals to grow their own food
often crops need lots of water where the supply is unreliable
people growing crops are exposed to chemicals without protective clothing
how has increase in demand for nonseasonal products had an impact on LICs in a positive way
jobs created
wages=tax paid government
what is organic farming
farming which does not use chemicals pesticides and fertilisers
why has demand for organic products risen
to protect environment by using natural preditors to control pests
people are concerned about effects on health
why is organic farming thought to be more healthy
farmers maintain good soil using crop rotation and natural fertilisers
weeds are controlled mechanically
animals are farmed without antibiotics and growth hormones
how has demand for organic produce changed and why
demand began to rise in 90s when people were worried about health demand fell between 2009-2011 due to global recession
what are food miles
distance food travels from producer to consumer
what is a carbon footprint
a measure of impact of human activity on environmnet in terms of greenhouse gases they produce
how does importing food increase uk carbon footprint
transport used to import food into uk adds CO2 into atmosphere and increases carbon footprint
is transport of food the biggest increase in foods carbon footprint
no CO2 produced when food is grown and harvested emissions caused by producing food in uk is sometimes bigger than transporting from overseas
why do we need to reduce food flown into the UK
to reduce carbon emmissions
how can we do this (5)
eat seasonal products grown in uk
limit imported foods to only ones you cant grow
limited food transported by air
eat locally produced food
grow food at home
what is agribusiness
treating food produced on farms like a business
how is this done (4)
increase the size of the farm by
removing hedgerow
combine smaller farms
use modern production methods
increase mechanisation
what are the causes of water pollution (8)
chemicals from farming run off farmland
hot water from cooling processes is pumped into rivers
rubbish is dumped
pollution from boats
untreated waste from industry
runoff from roads and motorways
people putting waste items and engine oil
pumping sewage in
how does water pollution effect the UK (7)
1 toxic waste poisons wildlife and can transfer to humans
2 drinking water can be poisonous
3 increased water temperature leads to death of wildlife
4 increase in fertilisers can increase nutrients in water, spreading up growth of algea so not enough O2 in water so wildlife die
5 pesticides can kill parts of the ecosystem
6 microbacteria in sewage can spread disease
7 people whose livlihoods depend on cleanwater may suffer
how is water quality in the UK managed (6)
legislation - strict laws for factories and farms
better treatment plants
pollution traps
greenroofs and walls
education campaigns to inform public about the damage
waster water treatment plants
how is the demand for energy changing and why
we are using less energy becasue of the decline of heavy industry but there is an increase in the amount used fore transport as there are more cars
what is the reduction in domestic energy explained by (3)
1 new energy efficiency devices
2 increase public awareness
3 increase in energy costs
