Black gold
Another word for oil, because it is so valuable
4 of 24
How might farming and food production be unsustainable?
There could be a problem due to a growing population, so the land cannot meet the demand. Also due to over cultivation, floods can occur, making yields even harder to harvest.
5 of 24
What is the perfect storm?
When global warming, population growth and other factors eventually combine to create a global disaster.
6 of 24
Why is urbanization a concern with regards to food production?
Fewer people, and less land is involved in production. Also the needs of water and electricity will increase.
7 of 24
How is the global hunger index calculated?
it is based on the number of people who are calorie deficient , children under 5 who are underweight and child mortality rate
8 of 24
How could improving child nutrition have the biggest impact on reducing hunger?
After the age of 2, negative effects of under nutrition are largely irreversible. The older generation would not be so ill, and could work.

What was the green revolution?
1940s- 1970s development of farming techniques were discovered. These include, GM, pesticides and fertilisers

How did this help the inhabitants of Mauritius?
They had a sustainable way of farming and security. The quality of life inproved. Knowledge of contraception meant the spread of AIDs would decrease.

What are renewable sources of energy?
Solar, Wind, Tidal energy, Wave power, Geothermal, hydroelectric

Why is Black Gold important?
It is used for may things, farming fertilizers, transport, 3% of oil is in plastics.
21 of 24
What is peak oil?
When oil production reaches its maximum, and then declines
22 of 24
What are pros of wind energy?
It could power the UK 8x over. The SOURCE of power is free. Cheapest form of renewable energy. Uk is the windiest country in europe
23 of 24
What are cons of wind energy?
Visual impacts e.g Blacklaw Scotland. Inefficient, lower % of energy is harvested. Not always reliable if it is not windy. Needs to be used with fossil fuels to be practical.
