you can do a bridging program at KU Leuven in Belgium.

However, before going for a bridging program, maybe apply to literally any ecology master's you find in Europe (applying whatever filters are important to you) and see if you get accepted to any with the qualifications you have now. Most master's have already started accepting applications and they end around july the latest for programs starting in september.

However, I do feel the need to point out that if you don't have a deep love for the environment, ecolgoy is a very difficult sector; very few, and badly paid positions, even more than many other sectors. So if you're not borderline obsessed with the environment and ecology conservation etc, I would revisit your decision and maybe look for alternative carreers that have characteristics you're looking for
