Can technology make a better world?

Our grandparents were a generation which lived without technology, how would be our lives if we had to go back in time and live without that comfort?

Perhaps technology has caused us some problems and has changed society, furthermore it has become a barrie between people. We had lost proximity, we are used to talk by social media before face to face.

Besides has affected to the ecosystem, because technology is produced by industry and industry uses technology. It's everywhere we go and this generates toxic gas which goes to environment.
Plus it's true that we're surrounded by technology airwaves and these causes diseases in our health that we haven't discovered yet.

Finally it has improved our life quality but we think that techonolgy should become healthier for humans and environment.
