Become a cyber-activist
One of the best ways to make yourself heard is to become a cyber-activist.
A cyber-what? Cyber-activism is about using the internet to tell your friends about something that concerns you - whether it be beach pollution or climate change.
That way you can encourage them to take action - either through writing letters to their politicians, or taking part in some hands-on activities.
Plus, you can share photos, stories and tips!
You can become our fan on facebook or start your own facebook page, a bebo group or a myspace page. Or if you're really keen, you can create your own website, or a blog using these sites.
