The discipline focuses broadly on environmentally sound and sustainable engineering solutions to meet societies' ecologically related needs.
[1][2] This major is sometimes called agricultural and biological engineering, biological and environmental engineering, etc., in different universities, generally reflecting interests of local employment opportunities.
Since biological engineering covers a wide spectrum, many departments now offer specialization options.
Depending on the department and the specialization options offered within each program, curricula may overlap with other related fields.
For example, biological treatment methodologies can be applied to provide access to clean drinking water [7] or for sequestration of carbon dioxide.
