Hi,

Psychology is the study of human behaviour and people turn out to be psychologist who counsels clients in different scenes like schools, hospitals and all other different places

Environmental sciences are the study of environment related topics that is conservation, protection, interventions, etc. People further work in related organisations or go into research.

Either way, getting a job after bachelors might not be possible as both are academic degrees and require more knowledge through masters or further studies.

I hope this helps.

All the best.
