Based on my own experienced that the number of birds decreased dramatically in my backyard in the last 7 years.
We did not observe red belly woodpeckers at all in the last couple years. Other birds not seen or very rare to show up in our garden:
- blue jay
- Mourning dove
- Carolina wren
- Carolina chickadee
- Northern Mockingbird
- American Crow
- other migratory birds
In fact, a scientist from UK as reported by Guardian (2004) and supported by the United Nation report (UN, 2019) estimated 1 million species will extinct by 2050.
Then, there are a lot of lists of animals will be disappeared in the very near future worldwide.
Top 10 animals expected to extinct soon are (Newsweek, 2020):
- Sumatran Rhino
- Lange's Metalmark Butterfly
- Māui dolphin
- Red Wolf
- Kauai Akepa
- Chinese Pangolin
- Attwater's Prairie Chicken
- Florida Grasshopper Sparrow
- Alabama Sturgeon
Who is the main actor as the greatest threat to survival of animals?
The absolute answer is human being!
What human being had done to contribute to lead to depletion of species? Here they are:
- destruction of habitats
- burning fossil fuel which cause climate changes.
