How is environmental science different from other science like biology and chemistry

Environmental Science is different from other sciences such as biology and chemistry because in this science, there are things that are impossible to predict. Some things that are impossible to predict are things like the weather, earthquakes, etc. There are too many factors that it is impossible to compute the outcome. Another unique thing about environmental science is fractals and chaos theory. Fractals are things that repeat itself over and over by chance such as snowflakes or lightning.
