According to Invasive Species Advisory Committee (ISAC), the definition of the invasive species is “a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health.”
But considering the following facts, why is this species not categorized as an invasive species? Homo sapiens:
is non-native to the most of the ecosystem which it is inhabiting, since it originated from a certain area of Africa and spread quite recently.
has often caused environmental problems by decreasing the local species after its introduction, as it is known that the number of species in the planet is drastically decreasing ever since the advent of Homo sapiens.
is likely to cause the same problem after introduced to new environment where homo sapiens hasn't inhabited yet.
