Have you ever just wanted to pick up and leave the foundation you call home? Kiruna knows the feeling.

Kiruna, a town in northern Sweden, built its riches upon the vast seam of iron ore, but the massive mine is now sinking the city of 23,000 residents. Now faced with a crisis, the town of Kiruna is moving to avoid catastrophe.

A dramatic shift has taken place in the glaciers of the southern Antarctic peninsula, writes Bert Wouters. Six years ago these previously stable bodies suddenly stated shedding 60 cubic kilometres of ice per year into the ocean. A stark warning of further surprises to come?

The same spring rains that lessen producers' concerns about drought can also lead to soil erosion and nutrient runoff. Keeping soil and fertilizers where they belong -- in the field -- benefits producers and the environment.

No-till farming, cover crops and rotational grazing will help producers reduce surface runoff to improve soil and water quality, according to South Dakota Agricultural Experiment Station researcher Sandeep Kumar, an assistant professor in the SDSU plant science department.

International Day for Biological Diversity 2015 is 22 May. The theme for the Day this year is “Biodiversity for Sustainable Development”. More than 4,500 mammal, bird and amphibian species are currently deemed at risk of extinction. Not all species have been catalogued, so we do not know exactly how many we are losing each year, but a report recently published in the journal Natuesuggests that approximately 41 per cent of amphibian species, 26 per cent of mammal species and 13 per cent of bird species are likely to be lost in the near future.

Entre el 10 y el 30 por ciento de todos los medicamentos recetados y vendidos en mostrador, quedan sin consumir, según un informe del Estado de Washington, y todos esos medicamentos sobrantes presentan riesgos significativos para la salud pública y el medio ambiente. Los medicamentos que se tiran por el inodoro o son arrojados a la basura, en lugar de eliminarse adecuadamente, pueden terminar en los océanos y vías fluviales, amenazando tanto la vida marina como la salud humana. Mientras tanto, muchos individuos no se deshacen de sus medicamentos no utilizados en absoluto; simplemente almacenan los medicamentos en sus botiquines, una práctica que puede dar lugar a un mal uso y abuso de drogas.
