Thousands of foreign plant and animal species have hitchhiked their way to new parts of the world, thanks to us humans. Every year, invasive species rack up damages totaling over $423 billion. These non-native animals and plants, introduced to regions through travel and trade, spread rapidly and can devastate local ecosystems. A recent study backed by the UN has shed light on the issue.
There’s an alarming addition of 200 new invaders annually. Many of them have harmful effects, such as water pollution, disease proliferation, crop failure, and even triggering natural disasters.
Since 1970, the costs incurred from these species have quadrupled every ten years. Ecologist Helen Roy suggests that what we see might only be “the tip of the iceberg.”
If unchecked, by 2050, we could see a 33% increase in invasive species from 2005 numbers. Climate change and altering land and sea usage can exacerbate the problem. A recent devastating wildfire in Maui, Hawaii, was intensified by dried invasive plants, marking it among the most destructive U.S. fires.
The issue isn’t localized. Even remote places like Antarctica aren’t immune, says report co-author Anibal Pauchard. Moreover, factors like habitat destruction, climate change, and pollution contribute to biodiversity loss, making regions more vulnerable to invaders.
The best strategy against this threat is prevention. This entails rigorous import checks and early detection systems. Fortunately, a commitment has been made globally to cut the introduction of invasive species by half by 2030. This recent four-year study aims to support that goal.
