Restlessness is a resistance to finality. Shakespeare and Beckett were restless writers. ‘Parfois tu sais, […] c’est pire de ne pas écrire que d’écrire’,1 Beckett told Raymond Federman in one of their last conversations. The necessity to write that is accompanied by a profound scepticism about the success story of an enlightened, humanist modernity is a stance shared by both Beckett and Shakespeare. Written on the edges of modernity, their works create and reflect on the very thresholds they represent. They articulate a restlessness between representation and what happens when representation becomes impossible.

As the study of our “house,” ecology considers interactions between humans and our environments. Hutchinson noted modern society’s effects, including from overconsumption, on the major cycles of nitrogen, carbon, and other elements, foretelling research on the Earth system. A major driver is agriculture, including the scale of pesticide use, an alarm sounded by Rachel Carson in Silent Spring. Industrial agriculture keeps crop ecosystems in a perpetual early state, Odum contends, trading off calorie production for services provided by more-mature ecosystems, such as water purification. Holling showed that ecosystems can exist stably in different states and be resilient to impacts. Pastoral ecosystems may not have a single equilibrium state, as shown by Ellis and Swift, with implications for development. Species play various roles in ecosystems, and their loss can affect key services, as noted by Ehrlich and Mooney. Conserving biodiversity will benefit from Indigenous knowledge, argue Gadgil and colleagues, including knowledge of the shifting baseline of fisheries, notes Pauly. As Earth urbanizes, rural to urban gradients present a growing research opportunity, McDonnell and Pickett argue.
