Scientific barriers : A commentary

Whatever the appeal of extreme integrism or holism, science is necessarily more utilist and partial. We can only address our environmental problems scientifically if we identify the most pressing and attack them first. To do so, we must break with the monistic ideals and traditions of both theoretical and mechanistic ecology to pursue particular solutions instead of global models. Statistical analysis of empirically identified patterns has proven effective in providing such solutions, perhaps because empirical patterns are less valueladen than theoretical or mechanistic alternatives or because such patterns are closer to experience and easier to understand. Unfortunately, such simple analyses are often less valued by leading ecologists who seek intellectual content rather than predictive power and practicality. To overcome this barrier to actionable information, the body of scientists must reaffirm their commitment to environmental action through their work as journal referees, grant reviewers, scientific critics and teachers.
