UN says fertiliser crisis is damaging the biosphere – Mass application of nutrients causes pollution in some areas while under-use hampers food production in others

By Michael McCarthy   18 February 2013 (The Independent) – The world is facing a fertiliser crisis, with far too little in some places, and far too much in others, a new report from the United Nations says today. The mass application of nitrogen, phosphorus, and other nutrients needed for plant growth has had huge benefits for […]

Wiping out species decreases resilience to climate change

24 October 2012 (PhysOrg) – It is tragic whenever any species is lost. Now it appears that the impact of species loss is far-reaching, much more than previously thought. The symbiotic relationships that develop in the environment as a result of high biodiversity make ecosystems more resilient to change. The loss of a species can […]

Graph of the Day: Lead Concentrations in Spinach Grown in Varanasi, India

This graph illustrates lead concentrations in spinach grown in Varanasi, India. (Singh, et al., 2010) Domestic wastewater comprises dissolved and suspended impurities from households. Untreated or insufficiently treated wastewater is typically contaminated with human excreta, which can cause traditional health risks. In recent years, domestic wastewater has been observed to contain trace quantities of pharmaceutical […]

Graph of the Day: Area of Mid-Summer Bottom Water Hypoxia in the Gulf of Mexico, 1985-2012

Record drought across the United States in 2012 followed a year of record flooding in the Mid-West in 2011, producing two very different areas of hypoxia, or oxygen deficient water, on the Louisiana continental shelf. The 2012 area of low oxygen, commonly known as the ‘Dead Zone,’ measured 7,480 square kilometers (= 2,889 square miles) […]
