Hay una alta probabilidad de que haya verduras frescas en su refrigerador que terminarán en la basura en lugar de en su plato de la cena. No es que alguien vaya a la tienda de comestibles con la intención de tirar más tarde la comida en la basura, pero todos lo hacemos más a menudo de lo que probablemente nos damos cuenta. Ruth Litchfield, profesora de ciencias alimentarias y nutrición humana en la Universidad Estatal de Iowa, dice que desperdiciamos alrededor de 20 libras de comida cada mes. Y eso es por persona.

There is a good chance there are fresh vegetables in your refrigerator that will end up in the garbage instead of on your dinner plate.

Not that anyone goes to the grocery store with the intention of later throwing the food in the trash, but we all do it more often than we probably realize. Ruth Litchfield, a professor of food science and human nutrition at Iowa State University, says we waste about 20 pounds of food each month. And that is per person.

The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions.

It was previously known that, in the long term, the deforestation of the Amazon rainforest has a negative impact on the global climate due to greater carbon dioxide emissions released into the atmosphere. However, researchers from Lund University in Sweden and other institutions have now shown that deforestation could also disrupt the entire rainforest’s resilience, that is, its long-term ability to recover from environmental changes, and the ability to absorb carbon dioxide from the atmosphere.

In a study published Thursday, researchers evaluated the effects of sudden flooding from the Tohoku tsunami on more than 20 bird species nesting on the distant Pacific islands. The results shed light not only on how those birds weathered the dramatic rise in seas from the extreme event, but also how island wildlife may fare with the threat of rising sea levels and increased storm surges.  

Many seabird species have disappeared from human populated higher islands, and their worldwide distributions are now concentrated on the low-lying islands protected as Wildlife Refuges and Marine National Monuments.

A research team led by The Australian National University (ANU) has found a new way to help plants better survive drought by enhancing their natural ability to preserve water.

The findings have helped some plants survive 50 per cent longer in drought conditions, and could eventually benefit major crops such as barley, rice and wheat, which are crucial to world food supplies.
