Other faiths offer different views, but for the purposes of this blog post I’m taking a look at four big challenges that present a serious threat to life on earth: water scarcity; increasing energy demand; food security; and climate change. What are chemical  engineers doing to tackle these issues and avert the apocalypse?

But it’s more complicated than that. The water, energy, food and climate change challenges are interrelated. The former Chief Scientific Adviser to the UK Government, Sir John Beddington, used the term Perfect Storm to describe this phenomenon arguing that climate change will intensify pressure on resources further, adding to the vulnerability of both ecosystems and people.

Chemical engineering can provide shelter from John’s ‘Perfect storm’.  Here are some examples.
