PORT OF SPAIN, Trinidad and Tobago, Guardian - The sudden death of a few fish and 150 or so corbeaux may not seem to be particularly alarming—especially the latter, as they are considered by many to have only nuisance value and are not blessed with the aesthetics of other birds. This may be one reason why the response of the authorities to date suggests they may not be treating the incidents sufficiently seriously. They do not seem to be sufficiently proactive in ensuring that the carcasses are swiftly and thoroughly tested to determine the cause or causes of the deaths, to ensure there are no recurrences or disastrous consequences, and either to advise people that they need not worry, or warn them what precautions they may need to take. That two unexplained kills have taken place in different places and among different species in so short a period should set alarm bells ringing. Even those without strong feelings for crabs, crayfish and corbeaux can understand that detailed investigations are necessary to ensure that whatever killed off these creatures does not pose a threat to human health and life.
