#2Does anyone know the source of those stats?
"steep decline of animal, fish and bird numbers was calculated by analyzing 10,000 different populations, covering 3,000 species"
Logistically speaking, I'd like to know how they tracked that. I've seen how caribou are tracking in Canada rather effectively (http://mffp.gouv.qc.ca/the-wildlife/hunting-fishing-trapping...)
However, specifics of their research I'd find very interesting if indeed I could see it sited.
Any help?

#3This article is from 2014. The fact that it is 2018 and we still have to convince people this is a bad thing is alarming.

#4Not coincidentally, the human population has doubled in the same timeframe.
Is everyone else screaming inside, or is it just me?

Problem is how many people really care enough to do much about it?

Planetary carrying capacity has to go somewhere. More humans + human animals and crops = fewer wild plants or animals
That's just an intuitive thought, I am not sure if it is necessarily correct in all cases. It certainly at least correlates.

#7Steep incline in usage of synthetics and synthetic pollution might also be a leading cause. We might have to use everything biodegradable and for long. No wonder cancer, premature babies, allergies have increased in past years.

Not by tracking, really, but I'd assume by population sampling. Rough counting of a species in an area or on a migration path, and then comparing it to historical data.

I think it's more brutal than that. How many humans are we willing to kill (or watch them die) in order to do much about it?
Most humans care some about animals, but they care more about humans.
(Yes, I am well aware that the developed world could accept a lower standard of living, and that would help. I question whether it's enough. And yes, I am aware that that is not an excuse for the developed world to do nothing.)
