How can you get job in ngo?

search the official website of one ngo, and there will be Words like "get involved", "employment", or "career". then click on it and see what jobs vacancies the ngo has.

however there are always very few job openings in the official website, and those jobs are not for people who actually learns environmental science, or zoology for post secondary education. so if you want to get a job that you could help plan something significant to make the world different, send your resume to their email or enquire in their office.
