Sustainability & Future Development Flashcards
(42 cards)
What are Developed Nations?
Developed nations – currently consuming resources much faster than they can regenerate.
What are Developing Nations?
Developing nations – have rapid population growth, and face the urgent need to improve living standards, with the associated demand for energy and resources.
Name and explain any events that happened throughout history that had trade and resources at their core?
Libya 2011
Iraq 2003 – The US and UK, invaded Iraq, with the fictional story that Saddam Hussein had Weapons of Mass Destruction (WMDs). This was not found to be true, and was more to do with establishing control over the nation’s oil, in a volatile region of the world.
Why does the energy demand increase while the population decreases?
As a nation becomes more affluent, their demand for energy increases, and the nation seeks to become more successful in terms of education, employs adequate health services and needs the infrastructure for these (roads, buildings etc.). And so as the population growth decreases, the demand for energy increases!
What does a sustainable society need?
- Stable or reducing population
- Very high levels of reuse and recycling.
- 100% renewable energy.
- No net loss of soil or biodiversity
How much are humans consuming?
According to the World Wildlife Fund / Global Footprint Network ‘Living Planet Report’, we are collectively consuming the renewable resources of 1.5 Earths
How many planets are needed to support the current world population
Global Foot printing Network data show that between three and four planet earths would be needed to support the existing world population at the present per-capita consumption levels of the UK
What way’s can the earth stabilise its population?
Option 1 – Happen sooner, through fewer births, this being the humane way of informed decision making on family size.
Option 2 – Happen later, by more deaths, the natural, inhumane way of famine, disease and predation of war.
What is the equation that is used to find the environmental impact of humans on the earth?
I = P x A x T I = Environmental Impact P = Population A = Affluence T = Technology
Who created this equation?
In the 1970s leading environmental thinkers were at loggerheads as to the main sources of environmental impact. Ecologist Paul Ehrlich and John Holdren identified population size and growth as the most urgent source of environmental impact.
This simple mathematical equation is generally credited to Ehrlich
What event occurred which resulted in an rapid increase in human activity, resource consumption and environmental impact?
The industrial revolution
human activity, resource consumption and environmental impact have grown relentlessly. We are now using many resources at a greater rate that they can be replenished.
As this continues, the resources become exhausted and in some cases irreversible damage is done to the environment and its ecosystems.
The quantity of resources we use and out impact on the environment effectively depend upon three main factors, What are these factors??
Population (P) – How many of us there are consuming resources and creating waste.
Affluence (A) – The average amount of goods and services we each use.
Technology (T) – How efficiently / harmfully we produce these goods and services.
The IMPACT is the combination of all three factors and it can be summarised by what is known as the Ehrlich or IPAT equation, I = P x A x T.
What is technology ?
Technology is the way that we convert natural resources into real goods and services that we can eat, drink, wear, live in, travel on, etc.
What is resource efficient technology ?
Resource efficient technology gives the greatest benefit for the smallest input of resources over the lifecycle of the ‘product’
What is the ‘lifecycle of a product’?
Stage 1 - The resources needed to make the good in the first place, i.e. the metals, plastics, minerals & fossil fuels required to manufacture a car.
Stage 2 - The resources needed to use the product, i.e. how much fuel you need for a vehicle per km (this will have a huge impact over the perhaps 200,000 miles the car may travel in its service life.
Stage 3 - The resources implicated at the end of the products service life, i.e. how much resources are needed to recycle the cars components, or dispose of the battery safely
Why is it still difficult to manufacture and supply goods using progressively smaller amounts of resources?
- Technology can only ever improve as far as the laws of physics allow.
- Renewable resources, including energy, are only renewable to a limited extent and are often expensive to harness.
What is the concept of sustainable design?
This requires exploring if a product is manufactured in the most energy efficient and resource efficient manner using minimal materials or components that can be recycled or reused.
What is affluence?
Affluence is all about wealth, and generally the wealthier a nation the most its citizens will consume. These can take the form of products, cars, TVs, laptops, phones, clothes, houses, schools / roads / bridges / water & sewer pipes – i.e. all different forms of infrastructure.
Why does developed nations have a high level of affluence?
Developed nations citizens have more expendable income, and so can afford more of these services and products, and hence they have a much larger affluence (wealth) than developing nations. They therefore have a very high value of Affluence. North America and Western Europe
Why does developing nations not have a high level of affluence?
Developing nations have much less expendable income (some are just about surviving) and as such they have much less affluence (wealth). They therefore have a very low value of Affluence. Most of South America and Africa would be in this category.
What is population?
Every person consumes resources and therefore has an impact on the environment.
What finite resources are needed more as the population frowns?
Finite amounts of land, water and energy resources have to be shared out between increasing numbers of people and the amount available for each individual gets smaller. More people means;
-More food and water required to sustain the population.
- More land is required on which to grow food.
-More raw materials are needed to provide clothing, shelter and other manufactured goods.
-Large amounts of energy are required for cooking, heating and industrial activity.
-Greater demand for resources increases the likelihood of conflict
-There is less margin to survive changes in the environment, be they climate change or natural disasters such as earthquakes and flooding.
Define ‘Ecological Footprint’
‘Ecological Footprint’ - compares human demands on nature with the biospheres ability to regenerate resources and provide services
What does the Ecological Footprint represent?
The Ecological Footprint represents the productive area required to provide the renewable resources humanity is using to absorb its waste. This value can then be compared to the biocapacity, which represents the planets biologically productive areas including our forests, pastures, cropland and fisheries.
