In my opinion, there are two things that threaten us as a species;
1.What we do to our environment
2.What we do to each other
Are we doomed as a species? I tend to have a little faith left in humanity. I do believe thought that the only way that we are going to survive is to first take care of our own, as a united species, that if cared for by having access to basic human necessities such as food, water, shelter, education (education is an interesting one as our education system is quickly being moulded by the commerce society that we live in. People, rather, are not being educated, they are trained to be productive and to live up to society's measure of success.) We have forgotten to teach how to learn and discover as opposed to how to make money.
"Every single problem you can think of, poverty, peace, the environment, is solved with education or including education," said Professor Negroponte.
We are not really in the "digital "age as-so-much as we are in the "consumer" age. No faster way to destroy our planet.
