The current social situation is that the rapid development of science and technology has brought about rapid economic growth, but the wanton development of ecological environmental resources, resulted in environmental deterioration, so that human survival faces major challenges. This is not only the current state of life but also an urgent problem that people will work together to solve. Therefore, in order to cultivate environmental awareness, make students intuitively and clearly understand the benign operation of ecological environment and the close relationship between people and the environment, this paper designs and studies the existing information technology to design biology teaching on the basis of the sustainable development of ecological environment and encourages students to strengthen the protection of the environment. This paper studied and designed the practical inquiry, analysis, and questionnaire survey. The experimental results show that the students in information technology teaching perform better than the traditional students, which can stimulate students' enthusiasm, arouse their interest in learning, and deepen students' understanding. The number of outstanding students increased by 5, and the number of failed students decreased by 8. The research significance of this paper is to provide new teaching design ideas for the existing biology teaching mode so that the development of information technology can benefit biology teaching.
