in my oppinion greatest threats are humans, their fear, their greed, their panic, and possible assosiations that find together to reach goals at the expense of others. like bitcoin for example.
And the more the technology becomes more and more advance its do the opposite on the environment the plastics, E-waste will more and more and will destroy the living things in this world. we need to recycle some of this for the benefits of human life to avoid of destruction of earth or even the human life also. focusing more and more to technology is not always the answer. People's being contented is the problem of the earth that why it cant stop if we dont recycle any of this even, it cant stop atleast it will lessen the destruction of environment and human life.
