lobbying your government, taking part in protests when they are held, siging petitions, donating money, donating clothes and other things, voting for someone different, using places like oxfam, being careful what you buy and where it comes from, buying fair trade goods.

little things like saving your pennies and putting them in a jar for charity. or giving a certain amount away a month either in a flat number or percent of earnings.

doing something that shows you care.
