Some entrepreneurs are already trying to create businesses that would give parents the ability to customize their child's appearance with CRISPR. Such alterations deeply concern scientists because the base human genome, known to scientists as the human germline, will be permanently changed.
Another concern held by scientists is the dangers of splicing the DNA of different organisms, especially humans with other species.
This could be dangerous for the subjects and especially dangerous if a group was able to create a CRISPR-altered superorganism. With this great power, humanity must tread lightly, for the world may be in danger if civilization is left unchecked to meddle with DNA of humans and other organisms. If civilization is left on its own to play God, a serious risk is posed to the future of humanity.
