I'm studying for my degree in geoscinces, Ifeel theres a need for useful info. & education for the world's pop. I am all for finding out how making changes however small can positively aid the needs of earth & all who live here with us. Everything seems to need assessing from the over-use of fossil fuels to the declining life in the oceans to those who are forced to live wearing political blindfolds when it comes to how the rest of the world live- being starved physically,psychologically & educationally.
