Dear MEL Topic Readers,
How human food is changing wildlife
Wildlife animals are supposed to feed themselves with food available in the wild, whether in the desert or tundra. And their biological mechanisms are built to live in their respective habitat. But when they find human waste and garbage, planted crops or fruits, or domesticated pet animals like dogs or cats, they naturally prefer such easily available edibles. For instance, a candy bar for a bear, trash bin for a crow, and a pet cat for a mountain lion. The problem is that when wildlife animals are fed by such unnatural foods, their biomechanism is also affected. One study found that bears that find unnatural human foods hibernate less and they live shorter. Also, while human foods tend to be richer in calorie, they are not as nutritiously balanced as the food or prey wildlife animals usually eat. Some say that it’s a double-edged nutritional sword for the species that depend on human foods.
As humans expands their territories to the wild, these kinds of encounters increase, and they cause health problems and a disruption to the lifestyle of wildlife animals.
Enjoy reading and learn how humans affect wildlife.
