Four Ways Microbial Fuel Cells Might Revolutionise Electricity Production In the Future
The world population is estimated to reach 9.5 billion by 2050. Given that most of our current energy is generated from fossil fuels, this creates significant challenges when it comes to providing enough sustainable electricity while mitigating climate change.
One idea that has gained traction over recent years is generating electricity using bacteria in devices called microbial fuel cells (MFCs). These fuel cells rely on the ability of certain naturally occurring microorganisms that have the ability to “breathe” metals, exchanging electrons to create electricity.
African Countries Must Protect their Fish Stocks From the European Union - Here’s How
Income accrued by small-scale fishers in Africa has reduced by up to 40% over the last decade. This is because less fish are available. It’s a huge food security challenge in places where fish are the only source of protein.
The reduced catch is also associated with rises in unemployment. In Senegal, for example, many blame fisheries agreements with the EU for destroying their livelihoods. This in turn pushes scores of young people to make the difficult and illegal journey to Europe.
