Scientists improve enzyme that eats plastic bottles
Scientists have unintentionally created a variant of a bacterial enzyme that is 20% better than the original at breaking down polyethylene terephthalate, commonly used to make plastic bottles. The researchers were investigating the properties of a bacterium that has naturally evolved to digest plastic.
Europe is the world's second-smallest continent by surface area, covering just over 10 million square kilometres or 6.8% of the global land area, but it is the third-most populous continent after Asia and Africa, with a population of around 740 million people or about 11% of the world's population. Its climate is heavily affected by warm Atlantic currents that temper winters and summers on much of the continent. In the European Union, farmers represent only 4.7% of the working population, yet manage nearly half of its land area.
