 Although nature was the focus of much nineteenth and twentieth century philosophy, contemporary environmental ethics only emerged as an academic discipline in the 1970s. The questioning and rethinking of the relationship of human beings with the natural environment over the last thirty years reflected an already widespread perception in the 1960s that the late twentieth century faced a human population explosion as part of a serious environmental crisis. Among the accessible work that drew attention to a sense of crisis was Rachel Carson’s Silent Spring (1963), which consisted of a number of essays earlier published in the New Yorker magazine detailing how pesticides such as DDT, aldrin and dieldrin concentrated through the food web. Commercial farming practices using these chemicals to maximize crop yields and profits, Carson speculates, are capable of impacting simultaneously on environmental and public health. Their use, she claims, can have the side effects of killing other living things (besides the targeted insects) and causing human disease. While Carson correctly fears that over-use of pesticides may lead to increases in some resistant insect species, the intensification of agriculture, land-clearing and massive use of neonicotonoid pesticides has subsequently contributed to a situation in which, according to some reviews, nearly half of insect species are threatened with extinction (Sánchez-Bayo and Wickhuys 2019, and compare van der Sluijs and Vaage 2016, Komonen, Halme and Kotiaho 2019). Declines in insect populations not only threaten pollination of plant species, but may also be responsible for huge declines in some bird populations (Goulson 2021) and appear to go hand in hand with cascading extinctions across ecosystems worldwide (Kehoe, Frago and Sanders 2021).
