Challenge 1 Flashcards
What is the title of challenge 1?
How will the UK’s population change in the mext 50 years and what are the implications of this for resource consumption?
How has and how will the population of the UK change from 1971 to 2031?
It went from 56 million in 1971 to 67 million today to an estimate of 71 million in 2031.
What implications are there of the increasing UK population?
Housing will become more expensive, so less people can afford housing.
There will more energy demand, so pollution may worsen.
Food and water scarcity will increase, so less food and water will be available.
Greenhouse gas emissions will increase as a result of higher energy demand and consumption.
What characteristics of deciduous woodlands are there?
Leaves fall off during winter
3 layers - canopy, shrubbery, ground
Broad leaved trees.
What characteristics of heathland are there?
Many birds breed as well as invertebrates.
Open countryside.
What characteristics of moorland are there?
Low pH, low growing shrubs.
Preserves dead organisms.
What characteristics of wetlands are there?
Areas of low-lying land, predominantly wet and boggy.
What characteristics of marine ecosystems are there?
Water around, fish farmed - high pollution.
Large and open (71% of Earth’s surface).
How will increased demand for housing increase pressure on ecosystems?
As more people live in the UK, more areas of heathland will be cleared to make way for new houses to be built.
This will lead to animals migrating.
How will increase demand for water increase pressure on ecosystems?
As water demand, more highland areas will have dams built to supply freshwater.
This may destroy highland forests.
How will increased waste increase pressure on ecosystems?
More waste will be produced due to a higher population so more landfill will be filled with waste, destroying habitats.
How are Voi scooters increasing sustainability in Bristol?
You can find them anywhere, so they are easy to
collect.
It is sustainable as it releases little CO2.
Bikes can be stolen however.
How is congestion charging increasing sustainability in Bristol?
A certain area fines you if you drive there in certain times, this prevents overpollution and is more friendly to pedestrians.
People may just drive around it though.
How are designated bus lanes increasing sustainability in Bristol?
Bus lanes are created to encourage civilians to use public transport, decreasing congestion.
This could increas traffic jams as it moves cars into one lane.
Which region will see the most growth?
South East + London
What will the UK population be by 2050-55?
78-80 million.
What result will increased demand for energy have?
Transport uses more energy, so more greenhouse gases will be used and cities will become more crowded and polluted.
Forests may also be cleared to gather the energy resources.
What will pressure on UK ecosystems lead to?
Increase in food production needed.
Growth in agribusiness.
Greenhouse gas emissions as more fossil fuels used.
Increased demand for water.
New housing gets built on floodplains.
Need for more housing. Pressure on greenfield sites.
What are the pros and cons of using sustainable energy sources?
Pros
Low carbon footprint
Cheap in many ways
Usable throughout the country.
Cons
Expensive in some circumstances
Inconsistent
Not as cost effective.
What are the pros and cons of using brownfield sites rather than greenfield sites?
Cheaper planning permission
Doesn’t disrupt the environment
Prevents areas from being left behind
More work needed for renewable energy
Structural issues could make it more difficult.
What are the pros and cons of switching to alternative energy sources to reduce greenhouse emissions?
Lower carbon footprint
Last longer
More expensive
Inconsistent supply
What are the pros and cons of managing river catchments to reduce risk and impact of flooding?
Cheap
Doesn’t affect environment
Doesn’t affect river flow
Doesn’t protect buildings
Can damage property
What are the pros and cons of educating people and businesses in resource conservation?
Helps take management out of government hands
Helps improve sustainability
Encourages more awareness
Expensive to educate everyone
Uses lots of resources
What are the pros and cons of finding new sources and reducing water wastage and leaks in homes?
Helps reduce landfill
Helps reduce the amount of waste water treated
Encourages less water scarcity
Costly to build
Requires lots of co-operation
