| What are the three main resources that are running out? | Food, Water and Energy |
| Why could they be running out? | They could be running due to many reasons.
-For energy, Fossil fuels are hard to extract, Non renewable energy are very good but some are expensive or not enough or some countries cant keep up with the demand.
-For food, Climate change doesn't do us a lot of help as it can dramatically change the weather. Diseases could wipe out farms and wars could destroy the food supply.
-Finally for water, clean water isn't equally distributed, Infrastructure could affect the transport of water and Wars could erupt to gain more clean water. |
| Why do we have a problem with those key resources? | Its mainly due to the Distribution of it.
-North America and Europe tend to have a lot more than parts of Asia and Africa because they can buy more.
-Also, as more people get richer and better developed, They will consume more.
-China and India are both consuming more at a rate which could be problematic |
| Why can African nations not extract the resources? | Reasons are that it can be really expensive to extract to get. It could also be that they don't have that type of tech yet. Another reason can be of corruption like in the DRC |
| Why is food a problem if countires can grow enough? | Because some countries grow food but not to feed people but for a cash crop. Kenya grows green beans and China and the UK buy a lot of them. |
| What could water shortage lead to? | It results into industries being shut down, people being hydrated, people being clean, growing food. |
| Is there demand of water going up? | Yes. In the future, the middle east, south Asia, China, USA, Mexico and Europe will demand much more. |
| What are the types of ways to harness energy? | 1. Fossil fuels which is ready made energy source so you can just burn it to make energy.
2. Nuclear power which makes heat energy from spillting atoms.
3. Wind power which uses the global cycle of wind to its advantage
4. Hydro power which is using the ocean and lakes to make power.
5. Solar Power which uses the Sun to make energy |
| What are the advantages and disadvantages of them? | 1.Fossil fuels are ready made so is very easy to use but does release greenhouse gases which leads to Global warming
2. Nuclear power is really powerful and can last for a while but nuclear waste can be expensive to get rid off. Also the safety concern of it.
3. Wind power do nothing to the climate but the NIMBY movement and its quite expensive to establish.
4. Wave power can make a lot of energy but could easily be destroyed
5. Solar power does nothing and is cheap but transferring the energy is a problem
6. Hydroelectric dams can help control the river but a mistake could mean catastrophic consequences
7. Tidal power can be a predictable energy source but is expensive. |
| What is water security and insecurity? | Water security is when you have more than enough water to pass the demand for water but water insecurity is when you dont have enough water to keep with demand. |
| What can affect the energy supply? | The energy side can be affected by:
Physical effects like where it is and limitations
Technology which basically is new ways of extracting resources but the problem is some countries might not be able to catch on.
Political effects like wars to gain the resource or to convert to non renewable which could challenge middle eastern and south american nations and finally,
Cost of the resource as since they are running out, the price will go up. So high that countries could be stuck. |
