Pigs originally bred to increase livestock production amidst Canada's cold weather seemingly evolved into intelligent super pigs threatening wildlife and farms in the United States. Several decades ago, farmers in Canada crossbred domestic pigs with wild boars, creating a hybrid breed of large intelligent pigs with the original intention of ensuring efficient pork production even during winter. However, the lack of market demand in the early 2000s led to many farmers letting the super pigs run free. Around two decades later, conservationists and environment experts sounded an alarm as the hybrid super pigs were observed to be scattering southwards or towards the northern part of the United States. The high tolerance of the super pigs to cold climate let them become superior in North American ecosystems, gobbling up tons and tons of other small animals. The super pigs are also stronger than the normal ones and have the capability of taking down animals larger than them, such as deer and elk. Conservationists shared that they are threatening both local wildlife and farms, since they can easily ravage the areas where they hunt. Aside from environmental adaptations, the super pigs also developed skills to fend off human hunters by turning nocturnal or even creating patterns that make them harder to locate. Scientists are trying to learn their patterns and numbers by attaching a GPS collar to a caught pig, showing the way to other pigs in the group. The super pigs could soon be a major problem for agriculture in the northern part of the United States, and conservationists are now devising ways to help control their population. The super pigs problem is a classic example of a long-term aftereffect of human activities messing up with the natural balance in the ecosystem.
