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.
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.
Last month, a Peruvian farmer called on German energy company RWE to pay its fair share to protect his home from imminent flooding caused by a glacial lake melted by global warming. “For a long time, my father and I have thought that those who cause climate change should help solve the problems it causes,” Saul Luciano Lliuya told the Guardian. He holds that RWE, one of Europe’s largest emitters of carbon, has contributed to the greenhouse effect causing glacial melting that endangers his home, along with many others in the city of Huaraz.
Lliuya’s story illustrates the tangible human impacts of climate change, which can easily be forgotten amidst high-level debates over carbon emissions reductions. This is a key year for climate action by both governments and companies.
Las últimas décadas han traído una explosión global de la electrónica con un enorme impacto en la calidad de vida y las comunicaciones, así como en la economía mundial.
Pero como la mayoría de los grandes cambios inducidos por el hombre, hubo consecuencias no deseadas, principalmente en la forma de montañas de residuos que resultaron como productos obsoletos y arrojados al fin sólo para ser reemplazados por otros con una igualmente corta vida.
A group of scientists, led by a team from the University of Bristol, has observed a sudden increase of ice loss in a previously stable region of Antarctica. The research is published today in Science.
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.
