Abstract

Humanity’s impact on the planet has surpassed sustainable limits, driven by population growth, consumption and limited efficiency gains (Bradshaw et al., 2021; Ehrlich and Holdren, 1971). While consumption in the Global North remains excessive, welfare improvements in the Global South require some growth in consumption. A smaller global population would aid sustainability, yet the current population exceeds 8 billion – well above most estimates of a sustainable size (Crist et al., 2022). Although modern contraception has reduced fertility, over 120 million unintended pregnancies occur annually (Bearak et al., 2020), and induced abortion remains vital for achieving desired family size and stabilising population growth (Tietze and Bongaarts, 1957). This article examines countries with total fertility rates (TFR) at or below replacement level (2.1), where abortion laws remain restrictive, and explores how access to legal abortion influences reproductive autonomy, population stabilisation and long-term environmental sustainability.
