The liliger is the hybrid offspring of a male lion (Panthera leo) and a female liger (Panthera leo♂ × Panthera tigris♀). Thus, it is a second generation hybrid. In accordance with Haldane's rule, male tigons and ligers are sterile, but female ligers and tigons can produce cubs.

The liger is distinct from the opposite hybrid called the tigon (of a male tiger and a lioness), and is the largest of all known extant felines .
Hybrid incompatibility occurs when the offspring of two closely related species are not viable or suffer from infertility. Charles Darwin posited that hybrid incompatibility is not a product of natural selection, stating that the phenomenon is an outcome of the hybridizing species diverging, rather than something that is directly acted upon by selective pressures.

If a human comes too close and surprises a sleeping or feeding tiger, or a tigress with her cubs, the tiger is prone to respond with aggression. Tigers have also been known to attack humans in cases of "mistaken identity" (for example, if a human is crouching while collecting firewood, or cutting grass) and sometimes when a tourist gets too close.
Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [1] and to ecosystems, biodiversity, and natural resources [2] caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects [3] [4 ...

An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
Environmental protection is the practice of protecting the natural environment on the individual, organizational or governmental levels, for the benefit of both the environment and humans. Environmentalism is a social and environmental movement that addresses environmental issues through advocacy, legislation education, and activism. [3]
