Khái niệm về hệ sinh thái không chỉ có các trung tâm sinh thái học chuyên nghiệp ngày hôm nay, nhưng nó cũng là khái niệm có liên quan nhất về vấn đề môi trường của con người. Trong giữa những năm 70, công chúng bị bắt giữ về ý nghĩa gốc của hệ sinh thái, cụ thể là "oikos" hoặc "nhà", mở rộng đối tượng vượt ra ngoài giới hạn học tập trước đây tương đối hẹp của nó bao gồm "toàn của con người và môi trường", hoặc toàn bộ môi trường nhà ở, vì nó được.
