LONDON - This year, Brazil produced 15 million tons of oranges. About 86% of those oranges were then turned into fresh orange juice. Imagine, then, the number of orange peels thrown away in Brazil.

The orange-peel abundance in Brazil is enough to attract attention from the British chemist James Clark, a professor at the Center for Green Chemistry at the University of York. Clark wowed the most recent British Science Festival by presenting a technique for converting orange peels into biofuel, using microwave energy. It is one of many research projects in the Old Continent attempting to develop biofuel in order to help reduce CO2 emissions.

Since the beginning of the war, more than half of the population — about 500,000 people — have left the city, even as others are flowing into Odessa from other war-torn regions in southern Ukraine, where the situation is even worse: people from Nikolayev, Kherson, Crimea, and even from Moldovan Transnistria.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.
