Use estar (está) for temporary conditions; ser (es) would imply a permanent characteristic.
La biodiversidad está la peligro.
The noun peligro is masculine, so it does not take a feminine article.

The preposition ‘en’ is enough; adding an article changes the meaning to ‘in the danger’ which sounds unnatural here.

Cultural Tip
In many Spanish‑speaking countries, environmental activism is a hot topic. When talking about biodiversity, a formal register is preferred in news articles and academic contexts, while a more informal tone can be used in everyday conversation. Be aware that some regions may use the word ‘fauna y flora’ instead of ‘biodiversidad’ to emphasize specific groups of organisms.
