1. Passive voice: "is covered by environmental laws," "is strictly illegal," "are set aside," "is not allowed," "are protected by law," and "is forbidden" all use the passive voice to focus on the actions and laws rather than the people enforcing them. This is a common and effective structure when discussing rules and regulations.
2. Relative clauses: "where building or farming is not allowed" and "so it's forbidden to harm them or remove them from their natural habitats" use relative clauses to add detail and clarify the restrictions.
3. Present simple tense: The answer consistently uses the present simple tense ("is," "are," "help") to talk about laws and general truths, which is appropriate for this context.
