During the early part of the 20th century the world underwent a chemical revolution and many new chemicals were formulated to promote the growth of plants (nitrogen), to kill pests (DDT), to keep our food cold (CFCs) and to prevent transformers from over heating (PCBs). After decades of use science showed that each of these chemicals had unwanted side effects including polluting water, killing birds, and putting holes in the ozone layer. Now these chemicals are banned or their use is strictly regulated.
During the second half of the 20th century the world underwent an electromagnetic revolution and many new frequencies were used for radio and TV broadcasting, radar, mobile phones1 and for a variety of wireless devices.
