There is a little bit of subjectivity in what constitutes a cause, ethical or conscious [sic] coin.
I'm not doubting you want to do good things, but spending money on these coins is hardly going to solve big problems, and we don't know what agendas you have, what agendas you will have in the future, and on.
You quote "science" as if it defines all that is good in humanity.
Yet science in itself means nothing really, and philosophers of science (the real ones, not Kuhn and the social sciences mob), rarely agree on what a scientific process is or what science is there to achieve. Christ, they are teaching creationism alongside Biology in some schools.
Then we have the nasty sciences, like eugenics (gaining traction again), vivisection, and all the work that goes into the process of making horrendous chemicals, poisons, toxins, nuclear power.
For most cause-coins you have the ability to influence the community as a audience member (with no vested interest), or as a member with a vested interest, orn as a community leader (with a vested interest). As a community leader you get to decide to do right or wrong.
If you care get involved and make a difference. You will learn that every little bit counts.
Just so you know, at EMC2 we are looking for projects to fund, so if you know of a school that wants a sponsor for their science fair we would like to do that, if you know of a youtube channel that wants sponsorship please let us know. If you know of someone that is doing something truly interesting in science and wants some encouragement, support, and money please tell us who that is so that we could consider him for recognition. We have funds ready to give, but not enough people to find the worthy recipients.
Would you help us in finding good science related causes to fund?
