What does a growing population mean? Give 4
More resources eg. wood
More food
More water
More energy
More houses
More services eg. hospitals & schools
How does a growing UK population impact people and the environment? Give 4
Increased urbanisation (urban sprawl) 🡪 loss of greenfield sites/risk of flooding
Loss of habitat (decrease in biodiversity)
Deforestation 🡪 loss of habitats/increased erosion/risk of flooding/↑ CO2
Increased pollution of air, land and water
Loss of farmland (housing)
Pressure on ecosystems (over exploitation)
More houses build on flood plains (20% of new homes) 🡪 increased risk
of flooding
Increased water scarcity (drought)
Increase in greenhouse gases (GHG’S) 🡪 worsening climate change
As the UK population continues to grow rapidly, it will place further p________ on housing and the
environment.
UK population growth is due to a combination of rising l___ expectancy, a relatively high b____ rate and high n__ immigration.

What is immigration?
Immigration is the process of moving to a new country or region with the intention of staying and living there.
Pressure on ecosystems comes from: Give 3
- building on greenfield sites
- the destruction of natural habitats and declining biodiversity
- pressure on water supply and quality
- increased food production intensifying agricultural practices.
A growing population exerts ever increasing p_______ on the e_________ and their goods and services.
D_____ for food, w____, energy and housing can affect the f______ of ecosystems and their biodiversity.
pressure
ecosystem
Demand
water
function
Why are UK ecosystems impacted by population pressure to different degrees and in different ways? Give 2
Local population pressure
Suitability of the ecosystem
Some are better managed than others.
Some are better protected by laws
What impact would the use of fertilisers and pesticides have on ecosystems?
Fertilisers - Impact on aquatic ecosystems through run-off 🡪 Eutrophication
Pesticides – Change the diversity of species. Bee population in decline - a primary pollinator - 30% crops +
90% of wild flowering species.
What might increase the yield of wheat in the UK?
Chemicals and new technology have helped increase the yield.
What are 2 impacts of increased food demand on ecosystems?
Overgrazing in upland areas
Draining of wetlands to create more farmland
Clearing of woodlands
New s____ and w___ farms will place pressure on UK ecosystems,
particularly in u_____ areas and the
m_____ ecosystems.
The UK Government has said that
new g__ f____ power stations need to be built to replace o__ power stations which need to be retired.
solar
wind
upland
marine
gas fired
old
Give 3 ways Climate Change can also impact on Ecosystems in the UK?
1) Milder winters/more storms
2) Increased risk of drought
3) Increased risk of fire
4) Change in species
Changes in l___ use and environmental pressures have led to d_______ in the number of species.
Increasing the production of food w_____ safeguarding ecosystems is a major c________.
land
declines
whilst
challenge
How Can the UK Reduce the Impact of an Increased Population on Resources and Ecosystems? Give 4
1) ‘Buffer zones’ around fields that are left to nature. Help absorb excess runoff from fields.
Provide valuable habitat insects, birds and mammals.
2) Move to more organic agricultural methods. Reduce use of pesticides and fertilisers.
3) Nature corridors to connect wild areas.
4) Stricter regulation on the use of chemicals.
5) Reduce food waste- wonky veg!
6) Building higher density and using brownfield sites so greenfield sites could be used for farming
and habitats
7) Choose alternative sustainable energy sources to meet increased demand and reduce GHG
emissions
8) Find new water sources and reduce water wastage and leaks to boost domestic water sources
9) Manage river catchments to reduce flooding risk/impact
What does sustainable transport mean?
This involves maintaining the standard of transport that is required for society and the economy without
placing too much pressure on the environment.
Cambridge and London sustainable transport:
Cambridge – Park and Ride, Cycles and Car Sharing
London – Congestion Charge, Santander Cycles
Give 4 Sustainable Transport Schemes:
Car sharing
Cycle hire
Congestion charging
Lanes for 2 or more people
Traffic flow lanes
Cycle lanes
Bus lanes
Public Transport eg. trams
Talk about London sustainable transport in more detail:
1) In 2003, London introduced the congestion charge, designed to reduce the amount of traffic in central London during certain times of the day. It would reduce congestion and pollution. The money collected is used to improve London’s Transport System.
2) Congestion Charge (CC): Operates 07:00-18:00 Monday Friday, 12:00-18:00 Saturday-Sunday and bank holidays. No charge between Christmas Day and New Year’s Day bank holiday (inclusive)
3) By 2019, it had the following benefits:
-> Traffic reduced by 39%
-> 65,000 fewer car journeys a day
-> Increase in bus passengers
-> Increase in cycle journeys
-> 12% less nitrous oxide
4) London also has Santander Cycles – public bike hire scheme - costs £2 for unlimited journeys up to 30 minutes, within a 24 hour period. For journeys longer than 30 minutes, you pay £2 for each additional 30 minutes.
-> In 2014 32 million bike journeys made
-> Cycling increased 400% by 2025.
5) Ultra Low Emission Zone (ULEZ): Operates 24 hours a day, every day of the year, except Christmas Day (25 December)
6) Low Emission Zone (LEZ): Operates 24 hours a day, every day of the year.
The daily Congestion Charge in London is now:
- £15 if paid in advance or on
the day of travel - £17.50 if paid by midnight of
the third day after travel
Park and ride schemes allow…
… shoppers to park their cars in a parking area on the edge of the urban area and catch the bus into the town centre.
They help reduce congestion and pollution in the town.
Park and Ride 2 points:
- Cambridge has 5 park and ride sites covering all the main routes coming into the city centre.
- There are 4,500 spaces available at Cambridge’s 5 park and ride sites. Double decker buses carry up to 70 passengers and leave the parks every 10 minutes during the day from Monday to Sunday.
- The Madingley and Trumpington Road park and ride sites in Cambridge are next to the M11. The Milton and Newmarket Road sites are close to the A14, giving easy access for motorists driving into Cambridge from the area.
- The park and ride sites in Cambridge are well lit and have security systems operating during opening hours. There are waiting rooms, toilets and baby changing facilities.
Describe the Car Sharing scheme in London:
Anyone who lives or works in Cambridgeshire can sign up. Enter journey details and a commuter is matched with people travelling the same route.
What is the Two Speed Economy?
This refers to the idea that economic growth within the UK is not uniform.
The south east of England has higher and faster economic growth which leads to better social and economic opportunities, better quality of life and improved health outcomes.
