Why should Disneyland be more sustainable?

Because they use a lot of energy

According to the book "Little Known Facts about Disneyland", Disneyland consumes around 1 million Kwh per year. Although Anaheim has a publicly owned utility department, and Disneyland's rates are lower than what most others in the region pay who use Southern California Edison or Pacific Gas and Electric, that doesn't change the fact that they are using a lot of energy. (Hoffman, David)

People look up to it, as ideal (role model)
Disneyland should be a role model for its wide diversity of guests. Disneyland can be seen as an ideal place- an ideal place should be 100% sustainable!

Wild life in the park Disneyland needs to be more sustainable, not only to protect its people, but to protect the environment and all the animals that live there!

They generate tons of trash! (literally!)

Disneyland generates over 30 tons of garbage each day and approximately 1,850 tons each year. (Disney Challenge)

The cleaning crew uses 500 toy brooms, 400 dustpans, and 5,000 mop heads a year to keep the place clean! (Fanning, Jim)

Disney's other parks in Orlando, Florida seem to be making more of a sustainability effort than here at Disneyland in Anaheim, California. http://www.benefits-of-recycling.com/disneysustainability.html (Disney Sustainability)

Good citizen

Disneyland should support the people that support them. For example, Disneyland should be buying their fruits and vegetables from local farmers markets which would not only to benefit Disneyland, but the local farmers can benefit as well.
