[19] As recently as 2016, a Chinese subsidiary mining company in Bolivia ignored signs that they were encroaching on uncontacted tribes, and attempted to cover it up. [20]
Although there are several examples of inbred populations of wild animals, the negative consequences of this inbreeding are poorly documented. [citation needed] In the South American sea lion, there was concern that recent population crashes would reduce genetic diversity. Historical analysis indicated that a population expansion from just two ...
Animals only rarely exhibit inbreeding avoidance. [1] The inbreeding avoidance hypothesis posits that certain mechanisms develop within a species, or within a given population of a species, as a result of assortative mating and natural and sexual selection , in order to prevent breeding among related individuals.

It's estimated about 77 isolated tribes willingly live in deep within the Brazilian Amazon - the most in the world, according to Survival International. These indigenous are typically very healthy ...
Invasive organisms brought by extraterrestrial civilizations could cause great ecological harm because of the terrestrial biosphere's lack of defenses against them. [45] On the other hand, pathogens and invasive species of extraterrestrial origin might differ enough from terrestrial organisms in their biology to have no adverse effects. [45]
These sites occurred as a result of humans exploiting an animal's herding behavior and predator-flight instincts. [citation needed] The extinction of the passenger pigeon is another example. [citation needed] In 2023 alone, over 1.8 million distinct human-wildlife conflicts occurred as animal involved auto accidents on roadways, seen as roadkill.
Some examples of diseases transmitted by cannibalism in mammals include the human disease Kuru which is a prion disease that degenerates the brain. [4] This disease was prevalent in Papua New Guinea where tribes practiced endocannibalism in cannibalistic funeral rituals and consume the brains infected by these prions. [18]
