Depending on location there's enough underappreciated indirect economical benefits to them ('ecosystem services' is the term used these dayss). For example a city I live nearby is largely protected from flooding because it's main river is, close to city's borders, embedded in a big wetland serving as a buffer, as it has been since the river started to exist. Last severe rainfall (which was close to an anomaly) it became like 80% full. The costs of the thing not being there would be several orders of magnitude larger than what one can make in a lifetime using it as farmland for instance, yet there are people thinking that way.
