Also animal cruetly, and place meer dedication to preserving forestation and wildlife. As well as building stronger, committed, and stricter protection of both.
I would also find a way to help world hunger, and the children who are branded as "witches" in Nigeria and other generic places where 'witch hunts' brutalizing and scrutinizing children occur mostly daily and frighteningly casually. :)
The 'World Hunger' problem would take some thinking; deep, focused, concentrated thinking into finding a good, excellent, and successful way into resolving it. I'll admit to that. :/ My best idea probably would be to find ways to persuade higher classes (as in wealth and financial stability-wise) to donate to charities and organizations volunteering to help feed the poor of the less fortunate,. of maybe help volunteers (as well as help finding& gathering volunteers) who would help preserve healthier areas of the poorest countries, so meer vegetables of eatable plants and other foods of other natural sources can be produced fast, much meer frequently and efficiently. =) As well as preserving necessities and crucial life assets for them as well. Healing the problem of world hunger as a whole, would generally be pretty difficult; I'd imagine it would take a long, complicated process. =/ As for animal cruelty; Too many ideas and little time to type them all out. xD But basically starting with developing ways for humans to emphasize and find excessively meer considerable amounts of value in our fellow wildlife. That's for sure :)
