The most threatening change , from my perspective , is extermination of species .
在我看来，威胁最大的莫过于物种的灭绝。
In principle , then , extermination should be possible .
一般而言根除应该是可能的。
As examples , the scientists pointed to a number of technologies as diverse as experimental medical systems that interact with patients to simulate empathy , and computer worms and viruses that defy extermination and could thus be said to have reached a " cockroach " stage of machine intelligence .
On the face of things , there are few more powerful forces for the extermination of languages than it .
从表面上看，几乎没有比信息技术更强大的力量可以使语言走向灭绝。
Capitalist countries also participated in great historical injustices such as the african slave trade , extermination of indigenous peoples , and imperialist exploitation of colonies .
