Diana Walstad's Ecology of the Planted Aquarium
maybe not a tech book, more like anti-tech, aanyway well worth reading even if you dont have any aquariums.
The Global status report on road safety 2023 shows that the number of annual road traffic deaths has fallen slightly to 1.19 million. The report shows that efforts to improve road safety are having an impact, and that significant reductions in road traffic deaths can be made if proven measures are applied. Despite this, the price paid for mobility remains too high. Road traffic injuries remain the leading killer of children and young people aged 5-29 years.
Yes - the effect is seen when they improve visibility at road junctions in a effort to increase safety. Before, everyone approached the uncertain situation slowly. Afterwards, they rush head-on into collisions.
Where I live there is a stop sign before merging into a major road despite originally good visibility, so few people actually stopped, which apparently led to accidents. Then they installed some barriers to make visibility worse (so drivers will not see the traffic on the main road until shortly before the stop sign, more or less forcing them to stop and take stock of the traffic situation, unless of course they are very irresponsible). Not sure if this has improved safety, but the barriers have been there for some years now, so I guess they were at least a bit successful...
>The results of the study indicate that potatoes show significant potential for
successful cultivation under PV modules. The reduced solar intensity caused by
shading does not severely hinder potato growth, suggesting that solar panel
installation on farmland can coexist with potato cultivation. The findings reveal that
potatoes can adapt to lower levels of solar radiation, making them suitable for
cultivation in shaded areas.
