These are threats that have emerged recently due to technological progress or increase in the human population, etc.
These threats are still poorly understood because they are less visible than the historical threats. In fact, only necropsy can tell the exact reasons for the death of an animal. However, the number of recovered bodies can be very small compared with the total number of dead animals.

These new threats include:
- Marine debris
- Chemical pollution
- Illnesses
- Offshore energy
- Capture of live animals
- Global warming
- Noise pollution
