Discussion Ideas
Read about the Longitude Prize in the BBC article, and then take a look at the six potential challenges. Which do you think professional and citizen scientists should try to solve?

DEMENTIA: How can we help people with dementia live independently for longer?
- It is estimated that 135 million people worldwide will have dementia by 2050. This presents a great personal and financial cost to society, and with no existing cure there is a need to find ways to support a person’s dignity and extend their ability to live independently.
- Dementia places a burden not just on the health-care system but on individuals, families, and networks of care. With a growing global financial and social cost, an integrated care solution is required.

FLIGHT: How can we fly without damaging the environment?
- If aircraft carbon emissions continue to rise they could contribute up to 15 percent of global warming from human activities within 50 years.
- The rapid growth of carbon emissions caused by air travel needs to be addressed to help tackle climate change. The potential of zero-carbon flight has been demonstrated but it has had almost no impact on the carbon footprint of the aviation industry, which still relies almost exclusively on fossil fuels.

WATER: How can we ensure everyone can have access to safe and clean water?
- Clean freshwater is becoming an increasingly rare resource. One in 10 of the world’s population doesn’t have access to safe drinking water. Forty-four percent of the world’s population and 28 per cent of the world’s agriculture are in regions of the world where water is scarce. As water requirements grow and our water reserves shrink, many are turning to desalination—but current technologies are too expensive and damage the environment.

FOOD: How can we ensure everyone has nutritious, sustainable food?
- By 2050 it is estimated that 9.1 billion people will be living on our planet. As the world’s population grows, gets richer, and moves to cities, their tastes will turn to more resource-hungry foods such as meat and milk.
- The problem is multifaceted; solving the global food supply problem is not just about tackling starvation. Many people are not starving, but they do lack nutrients in their diets, making them unhealthy. We cannot rely on replicating carbon-intensive and unhealthy western diets in order to solve this problem.

ANTIBIOTICS: How can we prevent the rise of resistance to antibiotics?
- On average antibiotics add 20 years to each person’s life. The development of antibiotics has been vital to our survival, yet the rise of antimicrobial resistance is threatening to make them ineffective in the future.

PARALYSIS: How can we restore movement to those with paralysis?
- In the UK eight people become paralyzed each day. Paralysis can emerge from a number of different injuries, conditions, and disorders and the effects can be devastating.
