Jennifer Kahn: Gene editing can now change an entire species — forever   (script)
Summary
Malaria now kills people a lot in the world. However, using pesticides damages other species gravely.
Is it right to use gene drive to protect them? Gene drive can make malaria parasite impossible to survive inside the mosquito. However, I think that I feel it fear.
It's because 1) it's so effective that even an accident release can change an entire species but it's very quick. It can invade other species. 2) Gene drive can be done by any lab. It's easier than we think. 3) Scientists think that gene drives are not frightening. 4) However, humans have a tendency to assume that the safest option is to preserve the status quo. It makes me worry somehow.
The speaker also said that it can be frightening to act, but not acting is worse. Now in the world, incredible gene recombination is invented.
Is this the world that be kept to safe?  We'll have to decide in the near future.
