Today is a good day to start donating to an environmental cause close to your heart. Whether you'd prefer to adopt an acre of the rainforest, or sponsor a humpback whale, there are plenty of ways to put your money in action. Send a lump sum or chose an option to have a certain amount taken out of your checking account to be directly deposited to the charity of your choice. If you're low on cash, think of fundraising opportunities like a yard sale or an online auction to sell items you no longer use.
