where to start working in conservation when already halfway through uni? (UK)

Hi, basically exactly what the title says. When applying for uni i had originally wanted to work with animals but unfortunately got a D (basically a fail) despite getting A’s in every other class, this was during covid when i had no access to internet as i come from a working class family. Anyways, i’m now looking for entry points into conservation work even though i’m halfway through an English Lit degree that isn’t really working out for me. I have one year of funding left and wonder if it’s best to leave after third year and attempt some sort of college? Any advice is greatly appreciated!
