Airplane crashes will continue as long as people use air travel, which is unlikely to ever change. The best we can do to prevent airplane crashes would be to build in enough security in airplanes so that enough amount of systems has to fail before a crash can occur, including eliminating human failure and cascading failures. Oil spills will also continue as long we extract oil from the bottom of the ocean (and to a degree land). In contrast to airplanes however, we should have a future where we stop extracting it from the earth. In order prevent climate change we need to stop today, and every day we continue to pump it up we are stepping further into catastrophe. We can have a future were electric planes flies in the sky. We can't have a future were we continue pumping up more oil. The oil need to stay where it is.
