Causes
I am interested in many, many things. But the following causes are very dear to me. 
The Israeli-Palestinian Conflict
The conflict started in the late 19th century with the influx of Jewish settlers, hoping to start a better life outside of (mainly) Europe. The flow of immigrants increased and shortly after the second world war, in 1948, the Jewish immigrants declared themselves to be an independent state, Israel. Ever since, conflict with both the local Palestinian people and neighbouring nations has threatened the lives of all involved.

She has struggled against the government through non-violence and has won the only democratic elections in the country. She remains under house arrest.

Education
H.G. Well once said, “Human history has become more than ever a rave between education and destruction”. I firmly agree. The question has become whether we can educate the world about civil liberties, agriculture, technology, infrastructure and education fast enough to remove dictators, solve environmental problems and remove the oppression of woman and minorities.
