Improving air quality — in clean and dirty places — could potentially avoid millions of pollution-related deaths each year. That finding comes from a team of environmental engineering and public health researchers who developed a global model of how changes in outdoor air pollution could lead to changes in the rates of health problems such as heart attack, stroke and lung cancer. Outdoor particulate air pollution results in 3.2 million premature deaths annually, more than the combined impact of HIV-AIDS and malaria. The researchers found that meeting the World Health Organization’s (WHO) particulate air quality guidelines could prevent 2.1 million deaths per year related to outdoor air pollution.

The Environmental Protection Agency took its first steps toward regulating the greenhouse gas emissions that escape airplane engines and pollute the atmosphere. The EPA intends to update the Clean Air Act, which was first introduced in 1963, to include jurisdiction limiting the emissions from these plane engines.

Researchers today outlined in a series of reports how governments, organizations and corporations are successfully moving away from short-term exploitation of the natural world and embracing a long-term vision of “nature as capital” – the ultimate world bank upon which the health and prosperity of humans and the planet depend.

The reports, published in the Proceedings of the National Academy of Sciences, suggest that significant progress has been made in the past decade, and that people, policy-makers and leaders around the world are beginning to understand ecosystem services as far more than a tree to cut or fish to harvest.

No es frecuente encontrar algo simple, factible y que también sea muy bueno para la salud, pero creo que esto sí: comer un medio puñado de frutos secos todos los días.

De acuerdo con un nuevo estudio de Holanda, sólo 10 gramos (aproximadamente un tercio de una onza) de nueces o maní (técnicamente una leguminosa) un día lleva a un menor riesgo de muerte por enfermedades respiratorias y cardiovasculares, enfermedades neurodegenerativas, la diabetes y la cáncer. No hubo beneficios de comer mantequilla de maní.

From heat waves to damaged crops to asthma in children, climate change is a major public health concern, argues a Michigan State University researcher in a new study. Climate change is about more than melting ice caps and images of the Earth on fire, said Sean Valles, assistant professor in Lyman Briggs College and the Department of Philosophy, who believes bioethicists could help reframe current climate change discourse. “When we talk about climate change, we can’t just be talking about money and jobs and polar bears,” he said. “Why do we focus on polar bears? Why not kids? Climate change isn’t just people hurting polar bears. It’s people hurting people.”
