Explanation:
The reason the passenger pigeon went extinct is because of the mass hunting that went on. The reason they were hunted was for their meat, which exploded in the market. Soon, their numbers started dwindling, and they were quickly approaching their demise.
Before long, the passenger pigeon was gone. The extinction of this species sent a ripple through the world. In a simple explanation, no more pigeons, no more pigeon meat. This was kind of the first step to conservation. The passenger pigeon, in a way, gave itself up for conservation and the protection of the other species. Thank you for reading.
