This article highlights John Cairns, Jr.'s many accomplishments in the areas of environmental science and sustainability.

We recently reported Cambrowania ovata Tang and Xiao in Tang et al., 2019, from the early Cambrian Hetang Formation in South China and interpreted it as a problematic animal fossil, possibly related to either sponges or ...

Aquatic ecosystems must play a major role to ensure that water, which is both essential and scarce, is always available for both present and future generations. This has become even more urgent in light of the ongoing ...

Rural Americans face barriers in access to services such as psychoeducation programs. The purpose of this study was to describe how participants in a rural Appalachian community, a geographic location that has been largely ...

Rapid climate change is causing ecological disequilibrium in many parts of the planet, which makes restoration of natural ecosystems to predisturbance conditions less probable. An alternative to restored ecosystems may be ...

Earth is changing rapidly to a hostile, alien planet. Humankind is using natural resources over 30% faster than Earth can regenerate them, and 215,000 more individuals are added to the global population every day. Species ...

In recent years, global warming has been ignored and scientists producing evidence supporting this hypothesis have been denigrated and even investigated. However, as irrefutable evidence showing that global warming was a ...

Sustainable use of the planet is an attractive goal, especially concerning intergenerational ethics. However, a major ecological tipping point has been passed (e.g, melting glaciers) and, in the last three years, evidence ...

Earth is a finite planet with finite resources, so any decisions humankind makes in the beginning of the twenty-first century will affect the lives of not only the future generation but the current generation as well. The ...

Tipping points may be passed when all appears well, and the changes that follow are likely to be swift and irreversible. A frequent analogy to passing tipping points is of passengers in an automobile driving rapidly through ...
