The source is petroleum, that dark viscous liquid found deep within the Earth, the product of once living organisms subjected to millennia of intense pressure and heat. It is not an understatement to say that petroleum is vital to modern life. It is of course used to produce the fuel that our cars, trucks, buses, ships and airplanes run on, but petroleum also furnishes the raw materials used to make our plastics, synthetic fibres, medications, agrochemicals and personal care products.</p> Wed, 24 Apr 2024 10:00:00 +0000 Joe Schwarcz PhD 9923 at /oss
