Do
n’t Let It Loose
Invasive species can out‑compete native plants and animals for food and space, damage ecosystems, disrupt food webs, and introduce parasites and disease. Across British Columbia and Canada, invasive species cost billions of dollars every year.
Some of the most serious invasive species were originally sold as pets or as plants for water gardens, ponds, terrariums, and aquariums. Water gardeners, aquarium and terrarium owners can choose from a wide variety of aquatic plants, invertebrates, reptiles, amphibians, and fish—but unfortunately, some of these exotic species have the potential to become invasive.
When pets or plants become too much for an owner to care for, they are sometimes released into nearby waterways, forests, or parks. This practice causes serious harm. Releasing pets or plants into the wild is both dangerous and inhumane. Some people believe that releasing an unwanted pet is the kindest option, but this is a misconception.
Most pets do not survive in the wild. Many die after being hit by vehicles, killed by predators, or from starvation and exposure. These animals are not adapted to local conditions and often suffer greatly. Releasing an animal into an unsuitable environment is considered animal cruelty, and charges can be laid under provincial legislation (BC SPCA).
Why This Matters
Some exotic pets and plants are able to thrive and reproduce once released. When this happens, they can:
- Out‑compete native species for food and habitat
- Prey on native wildlife
- Alter habitats and water quality
- Spread diseases and invasive parasites
- Permanently change ecosystem structure
Even if a pet or plant is native to parts of British Columbia, it should never be released. Captive animals and cultivated plants may carry diseases, parasites, or genetic traits that can harm wild populations.
Never Release Pets or Plants into the Wild
It may feel compassionate to “set them free,” but releasing pets or aquarium plants almost always leads to suffering and ecological harm.
Instead:
- Keep pets for their full lifespan
- Rehome unwanted pets through humane channels
- Return aquatic plants to retailers when possible
- Contact local animal rescues or aquatic societies for assistance
