The National Butterfly Centre in Mission, Texas, encompasses some 40 hectares of subtropical bush land along the banks of the Rio Grande. It's a refuge for more than 200 species of pollinating butterflies, as well as thousands of other species - flowers, birds, mammals and countless other insects.
The Trump administration's plan to build a border wall through the sanctuary will effectively destroy it. But such a loss will strike many as insignificant. Butterflies - so graceful and frail - seem almost a luxury rather than a necessity. Surely, the disappearance of a few more won't make any difference in the long run?
