After reviewing and publishing numerous short essays (brief notes and voices from practice) on social work responses to the pandemic of COVID-19, we have reflected on the challenges and opportunities during this centennial crisis. We are proud of our professional peers who are working with communities during very difficult times all around the world. At the same time, we may have to confess that we have mainly focused our eyes and minds on the well-being of humans. We always say that social work put efforts on various levels: the intra-personal, interpersonal, person-in-environment (PIE), intra-organizational, inter-organizational, inter-generational, and international. However, we pay a lot less attention to the sustainability of our natural environment.
