All governments should invest in experiments that can lead the world forward. This investment can pay huge dividends for the future of the world. Some experiments may seem silly, but the things learned from science has led to the technological revolution that we are all currently living today. Science is good.
Other governments should certainly consider investing in carbon dioxide conversation experiments, as climate change issues are not going away. The more innovation methods all countries have at their disposal, the better, and investments by one government can benefit the planet as a whole. This is probably more reasonable for wealthy countries to undertake, of course.
I think that all countries should be investing resources into scientific experimentation. Turning carbon dioxide into stone is a strange idea, but could turn out to be useful or lead to other important discoveries. Science is ever-evolving, and should be used for good, offering new and exciting ideas to our world.
Yes, governments should look into carbon dioxide conversion experiments. I believe that using carbon dioxide as stone could create new opportunities to create more environmentally safe housing. Using carbon dioxide stone could reduce demand for other, less natural building materials. Furthermore, if Icelandic scientists have already progressed so far with carbon dioxide, it can only be beneficial to have other governments conduct further experiments; the possibilities are nearly limitless.
