Today, innovations(创新) to make our lives more eco-friendly can be found everywhere. There are energy-efficient automobiles, eco-friendly light bulbs, and clothes made by fashion designers using sustainable(可持续的) environmental practices. Industries around the world have also begun to take a serious look at how their operations affect the local and global environment.

The university of Colorado has been named one of the top green colleges and universities in the United States. This university was one of the first to start a student-led recycling program in the 1970s and today supplies students with reusable shopping bags to use both on and off campus. The entire University of Colorado also uses low flow water fixtures(设备) and has reduced water usage by 40 percent since 2002.

When it comes to going green, Warren Wilson College has been recognized in many places. The Sierra Club and The Princeton Review have named the college as one of America’s greenest colleges and universities, while the school has also received the Outstanding College Recycling Award from the Carolina Recycling Association, as well as awards from the Association for the Advancement of Sustainability in Higher Education(AASHE). For a small college, Warren Wilson has made enormous efforts to be an eco-friendly campus since its beginning, and today owns a campus farm, a seeding program, and an extensive recycling program. Warren Wilson was also the first College to have an LEED platinum certified(白金认证的) residence hall, and its building services department is also 100 percent GreenSeal certified. According to College Stats, Warren Wilson College is one of the first institutions in the United States to be almost completely self-sufficient(自给自足的) while also engaging students to incorporate sustainability into all academic programs.
