Dear MEL Topic Readers,
Bird populations in US and Canada down 3bn in 50 years
Has the US and Canada become quieter? While human population has increased by over a hundred million in North America in the last half-century, the bird population seems to have declined by three billion, or nearly 30%, according to a recent study. The scientists who were involved in the study suspect that the key factor of the population loss was caused by human activities which affected birds’ habitats.
Another study conducted in Asia found that there are now more songbirds living in cages than in the wild especially in Java, the most populous island in Indonesia with a population of nearly 150 million and growing. Besides human activities that have reduced birds’ habitats, one major reason for the population decline is songbirds’ market. Where there is a demand, there is always a supply. Since bird singing contests are very popular and awarding, many humans want to get good songbirds for pride and prizes. So, lots of songbirds are captured in the wild for sale. It is unfortunate that even humans’ affection threatens other species lives.
Enjoy reading the article and think if humans could turn their affection for birds to conservation.
