They’re doing well on the internet. China’s Tencent and Alibaba are among the top 10 for 4 years already.
What: Non-USA companies that are in the top 10 public traded companies by market capitalization every year. Saudi Aramco is not included, because only a small fraction of its shares are traded publicly.
When: 1997-2020Q2
Where: I hope it’s the whole world except the USA.

Livestock. All this data is very unreliable, especially for animals living in the wild, but some rough estimates were made, and we know that there are probably 30 times more mammals kept as livestock than wild land mammals, and 2 times more birds kept as livestock than wild birds. Also, there are as many cats and dogs as animals in the wild.
These “quantities” are actually a total mass of carbon, which according to the Source make roughly 15% of total body mass. So, there might be lots of chicken, but they don’t weight as much as cows. The same with little wild animals – there might be more rats than cows.
Also, some types of animals were not taken into account, for example, reptiles, arthropods, sea mammals. I decided to concentrate on mammals and birds living above the ground. I’d include reptiles, but there are no reliable estimations about them.
What: Mass of carbon inside mammals and birds.
When: Data were taken from a study published in 2018, which used data from FAO. So, I guess it’s not very old.
Where: Land and above.
