The World Wildlife Fund said that 60% of the world’s wildlife has been lost since 1970. Overexploitation and agricultural activities remain the dominant causes of current species loss – of all the species that have gone extinct since AD1500, 75% were harmed by overexploitation or agriculture.
The harm is caused by an ever-expanding rate of human consumption. Over the past 50 years, our ecological footprint has increased by 190%. For instance, about six-billion tonnes of fish and invertebrtes have been extracted from the world’s oceans since 1950. Back in 1950, 28-million tonnes were caught, then in 2014, it spiked to more than 110-million tonnes. The peak amount was about 130-million tonnes in 1996 and it’s been decreasing by an average of 1.2-million tonnes per year since then.
The two most impacted regions are the “Neotropical realm”, composed of Central and South America and the Caribbean, which has seen their wildlife population decline by 89% and also freshwater ecosystems, which has seen a drop of 83% to their wildlife populations. Freshwater systems are abundant in Canada.
