More on lead

Previously we have discussed the effect of lead exposure on cognitive development as well its association with crime. ScienceDaily reports a new study that further confirms the negative effect of lead on neural development:

Higher lead in topsoil boosts the probability of cognitive difficulties in 5-year-old boys

Bottom line: any concentration of lead in the environment has a negative impact on the cognitive abilities of children. Since this damage is permanent, lead poisoning is a major social problem as reduced mental capacities will negatively affect performance at school and in later life.

Hence our position remains that the authorities in future space settlements should implement a zero tolerance policy when it comes to lead – any lead containing product should be banned from daily life.

Waste water – again

As regular readers of this site might already know, we believe that sewage and waste water treatment should be funded through the reclamation of valuable substances. For whom is not already convinced of this, we would recommend an article on GreenBiz by Yalin Li: Waste water is an asset.

Reclaiming nutrients and other valuables from waste water would constitute a durable source of non-tax revenue for governments and will hence structurally reduce the need to impose taxes on the people.
