Species biodiversity and wildlife population numbers have been declining in Canada for decades. According to the most recent Living Planet Report Canada, species that are deemed at-risk of extinction have experienced an average population decline of 59% compared to 1970. [24]
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
The Atlantic fishery abruptly collapsed in 1993 after overfishing from the late 1950s and an earlier partial collapse in the 1970s. [1] It is expected to recover to historical, sustainable levels by 2030. [2] In 1992, Northern cod populations fell to 1% of historical levels, in large part from decades of overfishing. [3]

The wildlife of Canada or biodiversity of Canada consist of over 80,000 classified species, [a] and an equal number thought yet to be recognized. [3] Known fauna and flora have been identified from five kingdoms: [ 4 ] protozoa represent approximately 1% of recorded species; chromist (approximately 4); fungis (approximately 16%); plants ...
According to the World Wide Fund for Nature's 2020 Living Planet Report, wildlife populations have declined by 68% since 1970 as a result of overconsumption, population growth and intensive farming, which is further evidence that humans have unleashed a sixth mass extinction event. [16] [17] [18]
Global populations of freshwater fish are collapsing due to water pollution and overfishing. Migratory fish populations have declined by 76% since 1970, and large "megafish" populations have fallen by 94% with 16 species declared extinct in 2020. [101]
