When I recognized the phrase " no trade, no killing," It was the article about an elephant. Due to illegal hunting, the elephants are fear of being endangered.
The ivory has become luxury products such as necklaces, stamps, and rings. The market is too huge to restrict. The more demand, the more we will supply.
The only way to protect the elephants is " no trade no killing."
I agree with this statement. We shouldn't destroy their habitats.
