Humans have had a profound impact on Earth’s ecosystems

 The Anthropocene is proposed as the current epoch, which is “viewed as the period during which human activity has been the dominant influence on climate and the environment”.  Many wildlife species, even if they are considered endangered, are overabundant in the ever-shrinking habitat ranges they occupy.

SpayVac®: A humane alternative

Overabundant species, even native ones, can reduce biodiversity by monopolizing resources, spreading infectious diseases, and changing species composition or relative abundance.
