A report by the WWF has suggested that stocks of tuna and mackerel in the seas have recently declined by 74% (http://www.theguardian.com/environment/2015/sep/15/tuna-and-mackerel-populations-suffer-catastrophic-74-decline-research-shows). Many other marine species, including Leatherback turtles and Sea cucumbers, are also in apparently terminal decline. Over-fishing is part of the problem but pollution also plays a role. We really need to manage what we do to the seas more effectively but that is going to be very difficult with increasing human populations and changing demands.
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.
