Clean Air: The Effects of U.S. Power Plant Carbon Standards on Human Health

By Roberta Attanasio A little more than a year ago, the World Health Organization (WHO) reported that in 2012 around 7 million people died — accounting for one in eight of total global deaths — as a result of exposure to air pollution. These estimates more than doubled the previous ones, and confirmed that air pollution is now the world’s largest single environmental health risk. The WHO concluded that reducing air...

Global Threats: Soil and Topsoil Erosion and Degradation

By Roberta Attanasio “Soil anaemia also breeds human anaemia. Micronutrient deficiency in the soil results in micronutrient malnutrition in people, since crops grown on such soils tend to be deficient in the nutrients needed to fight hidden hunger. (…) Managing our soil and water resources in a sustainable and equitable manner needs a new political vision.” M.S. Swaminathan — the “Indian Father of Green...

What is Carbon Farming?

By Roberta Attanasio Greenhouse gases (carbon dioxide, methane, nitrous oxide, fluorinated gases, and ozone) work like the glass walls of a greenhouse and are responsible for the greenhouse effect. What is the greenhouse effect? It’s a process in which greenhouse gases let the radiation from the sun onto the Earth’s surface. At the same time, they trap the heat that reflects back up into the atmosphere. The greenhouse...

Carbon Dioxide Fertilization Effect and Greening of Deserts

By The Editors Rising atmospheric carbon dioxide levels (CO2) are greening our deserts — in other words, many of the planet’s arid environments are greener than they would otherwise be if CO2 had remained constant. The greening of our deserts is due to the so-called CO2 fertilization effect, which can be defined as the enhancement of photosynthesis caused by rising CO2 levels in the atmosphere. Photosynthesis is the...
