       | nothing of the original ecosystem restoration agenda.

           | That's quite debatable. What is clear, though, is that the
           | city's current airport is bursting at the seams.

           | out.

       | Cue 'sunk cost' arguments.

       | > "Echeverria's vision for the park is part of a wave of projects
       | that have upended the traditional goal of ecosystem restoration:
       | returning ecosystems to the state they were in before humans
       | damaged them. Instead of seeking to roll back the clock,
       | Echeverria is creating an artificial wetland that aims to
       | transform the future of the entire Valley region, drawing lessons
       | from both Tenochtitlan and modern Mexico City on how thriving
       | cities can coexist with flourishing ecosystems. "
       | 
       | Part of the justification for this approach is the relatively new
       | recognition of the large ecological footprint of pre-European
       | peoples, and their extensive manipulation of the natural
       | environment, e.g. the use of controlled burns in grassland areas,
       | etc. "Pristine" environments were often not-so-pristine, so a new
       | managed system is not any different from an old managed system,
       | although you'd ideally want similar levels of ecological
       | productivity and diversity.
       | 
       | Another is that climatic effects are going to be significant,
       | e.g. in the long run the only way to save some species, such as
       | California redwoods, may be to plant new stands in Oregon,
       | Washington and Canada. This would be 'managed ecological
       | migration'.

         | want.

       | That's an interesting - and potentially misleading - take on
       | Axolotls and their habitat [ref.
