The upcoming arrival of spring has seen smog levels in Wroclaw shaprly decline in recent days, but activists are already looking at solutions to reduce pollution when winter bites back at the end of the year.
According to tuwroclaw.com, one solution is the construction of so called 'green walls', each of which would consist of two side panels of moss with a thickness of 2.2 metres, a height of 4 m and a width of 3 m. It is said that one of these green walls is as effective as 275 trees.
According to the WRO association, who have submitted the proposal as a candidate project for this year's citizen's budget, the green-walls offer the best short-term solution for dealing with Wroclaw's smog problem.
The walls would be placed in locations such as Rondo on Powstańców Śląskich, pl.Grunwaldzki, pl. Wolności, Kromera street and Kazimierza Wielkiego street. The total cost of the project would be 985,000zl.
