I think it is a threat to mother earth, but also a threat to our lives too.
Of course more technology has caused more environmental issues around the entire world. Technology is not as durable these days so people throw out old technology more often because theirs breaks easily, or the next new thing comes out and they have to get it. This ultimately leads to more pollution.
It is a threat to our lives as well because In Canada and the US the unemployment rate has gone significantly up since the 1900's. This is partially because of technology. Technology has over taken the jobs that majority of labourers used to have to do "back in the day." This has led to less jobs needed for factories and other industries because technology is able to do it all.
In conclusion I strongly believe that technology is threatening our lives and the life of the beautiful world we live on.
