This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Homing in on Horn Protection?
There is intriguing news that a co-founder of the Zululand rhino reserve has been given permission by the US Government to purchase the Arcturus T-20 military surveillance drone with a view to facilitating the protection of rhinos from poachers (http://mg.co.za/article/2012-12-26-saving-the-rhino-with-us-military-drones). Record numbers of rhinos have been killed this year for their horns. In Chinese medicine, this compacted hair is viewed as a cure (when powdered) for a number of conditions including fever (the aphrodisiac claim is not taken so seriously) and brings a very high price. The reserve would have to obtain permissions to fly the drones in South African airspace and I suspect (and hope) they would not be fitted with missiles. It is interesting that military pieces of kit can sometimes play a role in conservation.

Fishing on Land
There is a report (http://www.guardian.co.uk/environment/2012/dec/17/scottish-salmon-fishing?INTCMP=SRCH) that a company called Fishfrom is considering farming Scottish salmon in large, hanger-like constructions divorced from direct contact with the sea. The fish would be reared on cultivated Ragworm and, it is claimed, the technique could avoid many of the current problems of salmon fish pens (Sea lice infections, interrring with wild salmon viability, decimation of certain salmon food species etc). The 'fish factories' would recycle most of their water and use a combination of solar and hydro-electric power. It is claimed that many of the up-market UK retailers would be attracted to its product. I suspect that this might well be the shape of things to come but I wonder what hidden problems might arise in the future? Cultivating Ragworm and Salmon at high densities always seem to attract difficulties. Fish welfare is likely to be easier to monitor in such a system.

Galactic Mistake?
The news that Virgin Galactic is going to offer 'space' flights to paying trippers (http://www.virgingalactic.com/) and the UK Government is encouraging extracting gas from oil shales by 'fracking' (http://www.ft.com/cms/s/0/687dfe58-4508-11e2-858f-00144feabdc0.html#axzz2F8pXZcXA) don't seem exactly supportive of limiting 'green-house gas' emissions? It does seem strange that commerce can always trump environmental concerns.
