Increased use of fluorescent lighting as a climate change mitigation strategy may increase eye disease. The safe range of light to avoid exposing the eye to potentially damaging ultraviolet (UV) radiation is 2000 to 3500K and greater than 500 nanometers. Some fluorescent lights fall outside this safe range. Fluorescent lighting may increase UV-related eye diseases by up to 12% and, according to our calculations, may cause an additional 3000 cases of cataracts and 7500 cases of pterygia annually in Australia. Greater control of UV exposure from fluorescent lights is required. This may be of particular concern for aging populations in developed countries and countries in northern latitudes where there is a greater dependence on artificial lighting.
Experience shows that regulatory intervention can lead to substantial improvement in population health. The history of regulatory intervention in public health suggests that 'tipping points' necessary to catalyse regulatory change may be identified. We examine three areas in which governments have legislated to protect public health: sanitation, building standards, and vehicle emissions. We apply the lessons to regulatory reform addressing obesity and the chronic disease it causes.
With climate change and a burgeoning future world population there will be an increased need to reuse treated wastewater for a variety of uses including domestic water supplies as a water conservation measure. While there are technologies for partial treatment for the reuse of wastewater, in some areas of the world there is presently unregulated reuse of wastewater for agricultural irrigation activities which poses severe public health risks. Current water treatment technologies are inadequate to safeguard communities against water-related diseases arising from reused wastewater. There is an urgent need to ensure up-to-date knowledge about implementation of basic practices based on appropriate policy frameworks to protect human health and the environment. The knowledge providing more equitable outcomes with the reuse of wastewater is an overwhelming issue. There is sufficient evidence to question the current approach measuring faecal indicator organisms or coliform counts to establish microbiological quality of water and further complications arise from the presence of heavy metals, chemicals, hormones and endocrinedisrupting chemicals. The risks associated with populations exposed to recycled wastewater are uncertain requiring much more research, technology transfer and strengthened regulatory frameworks.
As the climate crisis intensifies amid some persistent public denial of the science, there exists a necessary opportunity for scientists to engage in transdisciplinary collaborations, such as those with artists and designers, in an effort to both improve the communication of climate science, but also to bolster the production of scientific knowledge. We demonstrate how art and design can activate the human imagination and promote collaboration across disciplines in a way that the post-Enlightenment scientific endeavor has historically been unable to do and can provide a framework for developing sustainable solutions to the climate crisis. Here, we describe 2 studies that involved collaboration between artists and designers and climate scientists. The first study paired a team of designers and computer scientists with climate and atmospheric scientists from the Jet Propulsion Laboratory in an effort to (re)build an exploratory research interface for the Multi-Angle Spectroradiometer Plume Height Project dataset. This project not only produced an aesthetic visualization interface with highly improved functionality, but it also demonstrated how an improved interface can enable scientists to pursue more and “better” research hypotheses. For the second study, we worked with artists at the School of the Art Institute of Chicago to create three sonic-based art pieces that effectively communicated the science of climate change, appealed to human aesthetic judgment, and expanded the scope of our “ecological awareness.” We show that, while collaborations between artists and scientists are not necessarily novel, the integration of art, design, and science from a project’s inception can improve both the production of knowledge and constitute an entry point for regular people to understand and engage with their rapidly changing planet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
