Biodiversity is rapidly declining across the globe.
Explanation:
The biodiversity across the globe has been under heavy blow, especially in the past few hundred years. The main reason for this are the humans. The humans with their activities have managed to destroy the habitats in lot of places, which in turn resulted in sharp decline in biodiversity. Also, some species have been systemically killed off, some because they have been considered as pests, some because they were used as a food source.
- Naturally, the biodiversity tends to be at a sustainable level, while some species die out, other replace them.
- In the more recent history though, there is a mass extinction occurring because of the humans activities, not because of natural causes.
- With the growing human population the trend of destroying the environment continues and it will continue further in the future, with the biodiversity constantly going down and lot of species ending up being endangered or extinct.
