Active on social media? Post a picture with caption that explains the wonders and importance of our ocean.
Meeting friends for food? Going on a date? Heading home for the holidays? Spend a few minutes informing them about the ocean. Start with a fun fact to get them interested. Here's a fun fact: did you know that sharks can shed up to 35,000 teeth in their life time?
Don't have stage fright? Find opportunities to speak to a larger audience, such as schools or companies. If you don't have connections to schools, ask your friends, family, or coworkers to introduce you to their children's teachers.
Realize the platform you are given and take advantage of it.
If you are a celebrity, or randomly pulled over for an interview, you've got yourself a big audience. When appropriate, talk a little bit about ocean conservation and how to be involved.
Whether you are an engineer, technical writer, or anyone that is given a chance to demo a function, post a sample code online, etc., it can be about ocean conservation.
If you are a shop owner, you can provide bags made of recycled materials and print out recycling instructions on them. You can also decorate your store with informational artwork about the ocean.
Whatever you do for a living, there is always a way to spread awareness.
