Pro Tips for Choosing Your Topic

• Use active voice when the actor (e.g., the researcher, the pollutant, the species) is the most important part of the sentence.
• Reserve passive voice for the 'Methods' section if you want to emphasize the process rather than the person performing it.
• In policy writing, avoid the 'passive of concealment' where the responsible party for an environmental hazard is omitted.
• Check the 'Instructions for Authors' in specific journals like 'Nature' or 'Science' as many now explicitly prefer active voice.
• Use active verbs to describe biological processes (e.g., 'The enzyme catalyzes...') to make your scientific writing more dynamic.
