The World Monetary Fund reports that food prices worldwide increased 43 percent in 2007-2008, and unpredictable growing conditions make subsistence farming, on which many depend, a risky business. Scientists with the U.S. Geological Survey (USGS) are part of a network of both private and government institutions that monitor food security in many of the poorest nations in the world.

Cropped image of an Acer pycnanthum mapleThe maple tree, admired for its glorious foliage and sweet sap, and seemingly ubiquitous in some parts of the world, is under threat of extinction. A recent study led by the UK-based conservation organization Botanic Gardens Conservation International (BGCI) has shown that nearly a third of all maple species are under threat of extinction in their native habitats. Of the 119 maple species assessed, 54 are considered at risk today, and a further 29 species are likely to become threatened in the near future.

Cropped image of a straw bale house under constructionA practice that started in the late 1800s is experiencing a sustainable resurgence as communities begin to construct super efficient houses out of bales of straw. In this article Emily Sullivan explains how using straw bales to build houses not only greatly reduces our footprint on the Earth, but also improves communities through job creation and economic improvement.

To put it in simple terms, the healthier the Earth is, the healthier its inhabitants. It’s something that is pretty obvious if only we stop to think about it, but since most of us are busy with our own lives, we fail to see how the two are interlinked.

Part of the solution to this problem depends on climate science, breakthrough technologies, and policy changes.
