In true quixotic spirit, officials of Castilla-La Mancha have invested €40m (£26.5m) in a network of "ecological tourism routes" that trace the knight errant's misadventures in La Mancha.
By furthermore considering the three dimensions of sustainability, we propose possible sustainability actions, i.e., we provide exemplary ideas on how to improve working conditions in production processes (social perspective) or optimization of delivery routes (ecological perspective) for instance.
However, fundamental ecological questions concerning the route of infection of lettuce by S. enterica and ecological factors influencing the colonization efficiency have not yet been described.
Instead, an occasional spill from the reservoir was diverted into a concrete spillway, bypassing the old riverbed and destroying the central linking piece of the route's ecological jigsaw.
Additionally, we may underestimate the overall contribution of protection, as many protected areas aim to protect biodiversity features not included in our analyses, such as beta diversity, particular rare species, migratory routes or ecological processes20.
The four main pathogenic species diverge according to their geographical distribution, ecological niche and transmission routes.
Their ecological niches remain unknown; routes of transmission and possible sources of these strains have not yet been recognized.
The promise of process intensification, as already expressed in the late 1970s, is to significantly increase the economic and ecological efficiency of chemical production routes.
Conversely, they are costly to build and maintain; they have ecological costs through blocking migration routes, restriction of biodiversity range use which may result in overabundance, inbreeding and isolation; restriction of evolutionary potential; management; amenity and ethical costs.
Ecological niche(s) and transmission routes have not yet been found.
