A “can’t do” attitude to maths is reported to have cost the economy £9 billion. And it will get worse, thanks to image the downgraded GCSE syllabus for maths where fewer pupils will be able to achieve good grades. I described it as “an education blackhole” in this post last month.

One reason that kids don’t connect with maths is because they don’t think they need to, that it will not be important in their lives as they can get all their answers on a calculator. I’ve been asked by my sons what is the point in learning algebra and geometry. They feel it is pointless. They don’t appreciate being able to exercise their brain cells in a different way, the joy of stepping out of their comfort zone and discovering that “eureka” moment.

What concerns me even more is the shortage of scientists in the UK, an issue I have highlighted several times. And our government is approaching this by promoting science in schools to take up a future career as a lighting expert at music festivals and Formula One engineers – more on this here. We have failed to focus enough on supporting our scientists with research to avoid a brain drain.

Every day now – and for the foreseeable future – we will read about food shortages, bio fuels, nuclear power, drought stress, climate change and tribal wars started by displaced communities in search of food and water.

We don’t have the answers to any of these major problems. All the best brains in the world cannot find a solution to them. It will take years of study and research to have proven technologies to overcome them. Some controversial questions will never be answered or consensually agreed. We need more scientists to be equipped with new skills to help face these daunting challenges.

In the meantime, a United Nation’s summit on resolving the world’s food crisis is being held in Rome. It’s farcical that Mugabe is there as Zimbabwe has an inflation rate topping 100,000%, and even subsided grains are unaffordable for many.

According to Oxfam, 80 percent of Zimbabwe’s population now lives on less than $1 a day, thanks to Mugabe’s policies, and lacks access to basic foods and clean water. This year’s harvest was poor, and Zimbabweans are fleeing their country in large numbers. Meanwhile, Mugabe is notorious for using food aid as a political weapon, distributing it only to those who reliably vote for him.

With many countries imposing export bans on food, it is clear that food has become a political weapon of the future.
