Collection of data in environmental science differ from many others in science:
The study of both natural and social sciences is called as Environmental science. It is based on environmental conditions affecting humans and living and dead organisms.

But in other biology/Science focuses on human cells and structure, functions, growth, origin, evolution, distribution and classification of all living things. It also deals with mechanisms around us.
