Help me Pay for Cornell University

I have been accepted to Cornell University, where I plan to major in Environmental Science/Sustainability so I can help lead the way for environmental preservation after I graduate.  While the difficult process of applying was completed successfully, I now have another obstacle for attending this prestigious university: money. I will be the one covering most of my assigned family contibution, which is $15300 a year by taking out loans and working while at school, but even then, I might still fall short.
Anything you can donate will be greatly appreciated, as it would be less money I have to take out on private loans. 
Thank you so much in advance!
