Do we need to protect our green spaces? In Switzerland, we lose around 2000 m2 of unsealed soil every hour.
Sealed areas are especially those covered by buildings, roads, or other structural measures. When soil is sealed – for example by construction, asphalting, paving, or concreting – it loses its permeability for water and air. As a result, it loses its ecological function as a habitat: plants can no longer grow, which also eliminates food sources for humans and animals. In addition, the soil can no longer absorb or break down pollutants, water, or organic material. During the same period (1997–201…
