Design eines T-Shirts

I´m looking for designs for my upcoming t-shirt business. I want this t-shirt brand to represent the fact that people aware of the big problems society faces and sick of looking the other way and doing nothing about it. It should be provocative. The main thought poppin into my head is: Do you Care? (can be used as a slogan, i think) The t-shirts will be produced by fair-trade companys and i want to donate a part for every sold shirt. So the company will serve for a good cause combined with faishon. I feel this idea has a lot of potential an i hope someday it becomes a symbol for humanitiy. So I need a design, that gives a look on the problems (war/refugees/ exploiting of the third world/ climate etc...) but is not to dark/depressive at the same time. So you can wear it nearly to every ocasion. I have already some ideas for designs, but i´m not sure about them, feel free to ask if you want. I´m also open minded, if you have suggestions for a logo for the brand. Of course these must be unique designs, not used anywhere else and full rights must be granted on acceptance.
