Consuming Resources
Flashcards do conjunto (27)
- 1What are resources?>Something that is 'found in the natural world that we need to survive'
>Something we use to 'make a living' - 2How much does the richest 20% of the human race consume? How much does the poorest 20% of the human race consume?> over 85% of all resources
> 1.3% of all resources - 3What are natural resources?Materials found in the natural world that are useful to man and that we have the technology and willingness to use
- 4What are human resources? What are material/capital resources?> The skills and abilities of the population
> A natural substance that humans choose to use - 5What is a non-renewable resource?> Can't be remade
> Once they are gone, they are gone
> E.g diamonds - 6What is a sustainable resource?> Can be renewed by humans and therefore will last
> E.g wood - replanting trees - 7What is a renewable sustainable resource?> They renew themselves and don't need managing
> E.g waves - 8'Have' and 'Have not' countries> Some countries have a large amount of resources whereas others don't
Countries with large quantities of natural resources may be more developed
HOWEVER, it doesn't always work like this
USA uses 25% of the worlds oil but has less than 5% of the world's total oil reserves - 9FACTS> MEDC's use technology to access resources
> MEDC's buy resources at low rates from other countries
> NIC's have developed because they are some resources - 10Malthus' Theory> Population grew exponentially but food production grew arithmetically
> Population would eventually outstrip food supply
> Population would decrease through starvation
> This was a 'natural check', other natural checks were war and disease
> Population would be reduced to a manageable level and would grow again until the next 'natural check' - 11Boserup's Theory> Food production does not limit or control population growth
> Population growth controls farming methods
> People would not give into disease or famine
> They would invent solutions to the problem
> 'Agricultural intensification' - farmers can grow more food from the same piece of land using better farming methods - 12Global Resource Case Study Oil consumptionOil is a finite resource
It's non-renewable
Known as 'black gold'
Used for pretty much everything - 13What is peak-oil?The point at which oil production reaches the maximum level and then declines
- 14Cheapest CarsThe location of the five cheapest cars are either in China or India which are both NIC's
The 'Nano' priced £1250 from India
The QQ3 priced £2500 from China - 15Hydrogen Fuel> Combination of many elements including carbon and oxygen
> Once separated it can be as powerful as oil
> Hydrogen is converted into making electricity which powers the engine - 16Pros and Cons of Hydrogen FuelPros:
> No emissions from hydrogen fuel
> Sustainable and Renewable
> Good alternative to oil
Cons:
> Expensive to make
> Transport emissions
> Emissions from separating the hydrogen - 17Why do we need to reduce the use of resources?> People are using resources at a 25% faster rate than the planet can renew them
> World has been in 'ecological debt' since 1897
> Estimates the Earth's ecosystems will collapse at this rate - 18What is sustainable development?Development that meets the needs of the present without compromising the ability of the future generations to meet their own needs
- 19Ways of reducing our use of resources locally> Use local farmers markets
+ reduces transport
- cost more energy to heat greenhouses in UK
> Reduce unnecessary luxuries
+reduces waste of resources and transport
- foreign workers might not have jobs
> Recycling
+ Huge savings of materials
> Cycling
+ no emissions
- older generations can't do this - 20How can we reduce use of resources on a bigger scale?> Eliminating waste
> Benign emissions
> Renewable energy sources
> Use resource-efficient transport
> Creating a new business model that demonstrates the value of sustainability - 21How can companies reduce resource demand?> 'Mission Statements' - frequently talk in terms of striving for sustainability
> Interface Inc.
> One of the largest manufacturers of commercial carpets globally
> Mission statement is very different from most - 22What is Interface Inc.'s mission statement?"Our vision is to lead the way to the next industrial revolution by becoming the first sustainable corporation"
- 23When will resources run out?> Silver = 9 years
> Uranium = 19 years
> Copper = 38 years - 24Julian Simon and Paul Enhrlich debate 1980Julian Simon said we wouldn't run out of resources as we were clever enough to find substitutes
Paul Ehrlich said that resources would run out - 25A Technological Fix> An innovation that can be used to solve a problem facing humans
> Tools machines and systems allow us to control nature and improve quality of life
> We have increasingly become dependent on new technology - 26Why is achieving sustainability important?> So we don't run out of resources
> So we can support the future - 27Ways in which technology can save the day?> Hydrogen Fuel
> Wind, hydroelectric and solar energy
> Biofuels
