Ayon sa assessment ng independent conservation organization na WWF at Zoological Society of London, bumagsak ng 73% ang wildlife population o bilang ng ilang hayop sa mundo simula 1970.

Sa mga rehiyong mayaman sa biodiversity tulad ng Latin America at Caribbean, umabot sa 95% ang pagbaba ng populasyon ng ilang mga hayop.

Anu-ano ang mga pangunahing dahilan at epekto nito sa mundo? Here's what you need to know.

01:30So people will see the numbers and potentially be alarmed,
01:32and I think it should be alarmed.
01:34Seeing this decline in the wildlife that we rely upon since 1970 is alarming.
01:38Catastrophic's a big word.
01:40I think we see different trends in different places.

03:57That's not something we should just put on the shelf
03:59and stop worrying about.
04:00We need to act now.
04:01The threats to those systems we see,
04:03things like habitat loss and degradation, over-exploitation,
04:06are also in part affected by things like climate change.
04:08It's not as frequently reported,
04:10but it seems to be a growing reported threat.
04:12The combination of climate change, habitat loss, and biodiversity loss
04:15are things that we need to get on top of
04:17because they're a mixed-up problem
04:18that needs to be dealt with together.

05:10I don't think it's too late.
05:11I think it's important that we take this as an opportunity
05:14to say something about it.
05:15I think the Living Planet Index,
05:16as one of the statistics of biodiversity that we like to talk about,
05:19should be seen as a warning.
05:20We should be able to do something about these systems
05:22to allow them to recover.
05:23That means doing just personal stuff,
05:25but also encouraging our governments to do stuff with it.
