The mid-20th century was the golden age of natural product discovery. Scientists discovered groundbreaking drugs, like penicillin and tetracycline, from sources in nature.

But as the search for natural products continued, pharmaceutical companies kept finding the same products over and over again. By the early 2000s, most of these companies shut down their natural product discovery programs.

In an age of booming biotechnology, it might be easy to forget how much we still rely on the bounty of the natural world. Some microbes make us sick, some keep us healthy, while others continue to give us some of our best cures in the form of naturally occurring products such as penicillin and tetracycline.
