If you were green long before the green wave, and you are interested in seeing where your career can lead you to, make sure you pay a visit to this site, which is a directory of job vacancies in Canada and the US, both for the public and private sector (and non-profits too), where you will be able to find openings for jobs that are somewhat related to the environment, like engineers, chemists, technicians, and geologists, but also for non-professional or technical jobs in eco-friendly workplaces, and for teaching/coaching positions as well. In this site, you will find a list of vacancies and a detailed description of the job and requirements, plus contact information so that you can submit your CV to your prospective employer directly; the service is free for job seekers, though companies who want to post their job openings have to pay for it (a full list of pricing details is available).
You will also find links to government, state and local jobs in the US and Canada, plus environment agencies (Department of Commerce, Agriculture and Energy are examples of that) for both countries. If you found a vacancy you are interested in, make sure you take a close look at the résumé area to find some cool tips on what you should put into your CV, and detailed instructions as to what you should bear in mind when formatting your résumé, taking into account that most of them get scanned afterwards.
