Most of the activity to driven by western demands for materials with little or no regard for the endangered animal and plant life in the area including Orang-utans, Sumatran tigers and rhinoceros. There are even suggestions that fires are started deliberately in these areas to speed up the deforestation process.

http://www.guardian.co.uk/environment/2013/may/23/conservation-agency-approved-cull-endangered-birds?INTCMP=SRCH). The colony is near the Bowlands Fells in Lancashire and the original excuse for the cull was potential contamination of the local reservoir by bird droppings (a highly contentious excuse, anyhow). It has now been claimed that the real reason for the cull's approval was the location of the circa 9500 hectare Abbeystead estate, largely maintained for grouse shooting. There is a claim that Lesser black-backs sometimes consume grouse eggs (hardly remarkable as this species, like many others, is opportunistic in its feeding habitats and the grouse eggs would constitute an artificially concentrated food source). It does seem strange that English Nature appeared to ignore one of its primary purposes (i.e. conservation of endangered species) over an extended period. Perhaps they thought it more important to stay on good terms with the land-owner?

http://www.guardian.co.uk/environment/2013/may/21/uk-species-struggling-wildlife) has confirmed that much of the UK's wildlife is in serious decline. Struggling species (60% of those analysed were showing serious declines) range from the Freshwater pearl mussel, a variety of insects (including the Garden tiger moth), Atlantic salmon, Hedgehogs, Greater horseshoe bats and Lesser spotted woodpeckers. That is not to mention the plants on which some of these animals (diestly or indirectly) rely! A few species (like the Red kite and the European otter) seem to be doing well, largely as a result of serious and continued conservation efforts over extended periods (including changes in the Law) but most of the endangered species suffer from habitat destruction, pollution and/or disturbance. The analysis largely blames intense agriculture (although others will argue that it is needed to feed increased human populations and to facilitate the production of some 'biofuels') but urbanisation (a process likely to be intensified by a drive to create millions of 'affordable homes') and climate change must also play roles. Even a greater human participation in 'outdoor activities' (needed for our health) including even studying natural history can make it more difficult for certain species. And don't start me on gardeners with their introduced alien species and the release of feral 'pets'!

It is even more remarkable that the event cannot even be ameliorated by monies from the US disasters fund which is reserved for hurricanes, earthquakes, bush fires, whirlwinds etc. Melting of the permafrost and the loss of land to increased volumes of water coming down rivers appear not to count at present.

http://www.bbc.co.uk/news/science-environment-22484907). It seems that warmer winters in Scandinavia have persuaded some of these water birds to resist migration (an energetically demanding activity).

The attainment of the figure so early, however, is a clear indication that attempts to contain the release of 'climate changing gases' has been spectacularly ineffective.
