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.

Wooden Tops?
The European Commission (EC) aim to plant 3bn trees across the EU by 2030. This is one part of their intention to put the EU on track to achieve a 55% cut in 'greenhouse gas' emissions by that date (https://www.theguardian.com/environment/2021/jul/16/enough-with-the-burning-eu-executive-accused-of-sacrificing-forests). The EC focus on some of the generated wood being 'biofuel'. Burning wood to heat homes and/or to make electricity, means that the carbon dioxide, captured by photosynthesis, is put straight back into the atmosphere. You might reduce this, by using carbon capture but this is only likely on major plants. Treating trees as a 'crop' also has some downsides. It results in people being incentivised to plant the fastest growing species rather than those with other beneficits. For example, the root systems of some species may be better at holding water and reducing the chances of flooding (topical, at present, in the EU) and landslides. It should be obvious to the EU (and everyone else) that we need to be aiming for substantial (and permanent) reductions in 'greenhouse gases'. The difference between a biofuel and coal/ oil/ gas is really only one of duration. The hydrocarbon fuels were in the rocks for millennia. Wood will only be in the trees, a few decades at best. One might consequently liken biofuels to short-term loans. Expensive and rarely solving the liquidity problem. I get the impression that policy makers are, playing for time, whilst hoping for a technofix.
