If you want to be an ecologist, then you need a degree, but if you really feel that you aren’t going to make it, there are plenty of other ways to have a career that makes a difference. Conservation is extremely wide-ranging and it’s not longer a field dominated by scientists. You need other skills as well:
- people skills
- management skills
… too many to list, but my advice is look for some volunteer programmes near you, and be a sponge and soak everything in. It will help you define where and how you can get to where you want to be. Experience is far FAR more valuable than a degree. Unfortunately it’s the standard way to start a career, but by no means is it the only way… Good luck!!
You are not Atlas carrying the world on your shoulder. It is good to remember that the planet is carrying you.
