Extremists are using chainsaws, toxic herbicides, fencing, and barriers to change Toronto’s natural park ravines to their personal vision of "native species" theme parks where nature can only be observed, not experienced. How absurd to believe that the species they claim are the natural flora of Toronto’s ravines must be planted by 21st-century activists, defended with chainsaws and poison, and barricaded behind fences. These tax-funded extremists must be stopped.
