I am not against science buddy @patrik27 but the sector we are using science most. We have a huge number of earth population who are devoid of pure water , why we don't search water for them? why not invest money to invent technology so that they can drink some pure water?
Instead we are searching water in Mars.
Thank you for clarifying. True that the issue of enough food and water for everyone has to be resolved urgently. And we are contributing to it in our own ways. Some of us work on the food issue, some are trying to get pure water, some work on pollution issue. We are all contributing to welfare in our own ways. But we also need to work on development and increase in our knowledge. All of these are important.
