First of all, I wouldn't even know who deGrasse Tyson was if it wasn't for sites like 4chan, reddit and hn. But apparently, he "has the world in his hands."
Secondly, I want to comment on this:
It’s hard to deny that we live in an era in which science — as both a worldview and as a practice — is under near-constant assault. On the left, there are those who rail against the dangers of GMOs and vaccines. On the right, there are those who deny climate change and the evolution of species."
Just because people are opposed to some applications of science, or skeptical of some scientific theories, doesn't mean science is under assault. Besides, science is defined by its method, so, the only people who could possibly pose any threat to it are the scientists themselves, should they forget this fact.
