Premise: Fearing that overdevelopment, as well as new trends and tastes in international tourism, would leave the Balearics behind, authorities have moved to protect remaining undeveloped areas as nature preserves, proclaiming them off-limits to all construction, and have even blown up some of the more unsightly hotel blemishes on the coasts.

Hypothesis: Overdevelopment could hurt the Balearics.
