I have also started to tweet quite a bit .. including to some journalists .. I think, eventually, these forms of social media could be a back door to more MSM interest; before social media, when I used to write to them “cold” not a single one ever replied. I no longer bother.
Essentially, we can live as one human species on one full planet, or we can live as dozens, hundreds or even thousands of separate groups competing with each other for resources that are only abundant if we stabilise (or reduce) our consumption of those resources. We have evolved to live as these small competing groups; if we do we not evolve a better alternative then the next few centuries will be very ugly indeed as Clive Hamilton argues in his reply to Andrew Revkin in "The Delusion of the Good Anthropocene".
