Hi Javier, I do think change is possible but I don't think it will come easily. When I say that, I'm thinking especially about global climate change. I think it will take a crisis of massive proportions to change our ways in that regard. With respect to social issues such as homelessness, inequality, and censorship for example, I again believe change is possible but I'm not hopeful. These are issues that humans have been dealing with for thousands of years. All I can do as an individual is try to focus on the small ways I can contribute. What do you think?
