I understand that this meeting is more extreme in many senses since there are so many eyes and ears focusing on the events. What an opportunity for some to make political statements and act on the lack of transparency that evokes frustration. Why fight on figures when we know how to develop sustainable systems. Why not just start a change and build businesses and social relations by transferring knowledge and know-how. Some of the negative feedback that I heard around me is more or less the same feeling as when my daughters are tired and hungry -they collapse in frustration and walks away! Today it is said that Venezuela and others will walk out and join the “masses” outside Bella Centre, we will see what happens!
We and hopefully the majority of environmental engineering firms, together with experts in authorities and ministries, know that the solutions are not always embedded in targets. Solutions have already been developed by evolution and by humans since some groups of people have seen the negative impacts of a hybris. Knowledge is so obvious that some do not see it!
-You find these solutions along the roadside. Did you know that a Beech, let say 20 meters high with a diameter of 12 meters produce solutions that are not appreciated by everyone. [A quite common three in our part of the world and probably less effective in terms of ecosystem services than trees that produce more green areas are in warmer climates]. Did you know that under a sunny Nordic day, a tree like this produce ecosystem services [with 600 000 leaves, 1200 square meters of leafs] as for example filtering of 9 400 litres of water, that could cause problem in the pipes. With a CO2-concentration 0.03%, 36 000 cubic meters of air must pass the system where the leaves filtrate and capsulate particles like bacteria, spores, dust and other dangerous substances such as nanoparticles from the roads etc. Finally, 400 litres of water humidify the air, how pleasant it could be sitting under a three and discuss solutions rather in a crowded Bella centre. If the trees does not fit into the planners vision of the concrete city, but you still doesn’t want to have problems with water etc. you must replant 2000 young trees with a economic cost in Sweden that might be estimated to almost 160 000 Euros. Why not use existing knowledge and just do it?
