allow nature to take its course

allow nature to take its course

To let events develop and conclude naturally, i.e., as they would without outside intervention, help, or interference. The phrase can refer literally to nature or figuratively to manmade situations or events. Though I know people are eager to help those affected by the earthquake, unfortunately we have to allow nature to take its course before anything can be done.
