The therapeutic benefits of time out in nature are now very well known and you can magnify those benefits when the nature you’re in is the Walls of Jerusalem National Park in Tasmania. The Park is breathtakingly beautiful and deserves the highest level of protection, not to have a For Sale sign put  up. Will Hodgman was no environmental guardian, Peter Gutwein, it seems, is not one either.

How to tackle climate change, food security and land degradation

How can some of world’s biggest problems — climate change, food security and land degradation — be tackled simultaneously? Some lesser-known options, such as integrated water management and increasing the organic content of soil, have fewer trade-offs than many well-known options, such as planting trees, according to a Rutgers-led study in the journal Global Change Biology.

New study sparks fresh call for seagrass preservation

An increase in carbon dioxide emissions equivalent to 5 million cars a year has been caused by the loss of seagrass meadows around the Australian coastline since the 1950s.

This has resulte in a 2 per cent increase in annual carbon dioxide emissions from land-use change.
