I just found a fascinating website today, Earth Portal. Instead of having a Wikipedia like system where anyone with a computer can edit and add to articles, Earth Portal has 150 authors whose credentials have been verified (along with a editor conversant within the field in question) writing articles about all things related to our planet and ourselves.
Find out how the body expels toxins, what a “dust budget” is, or the latest news about our planet. An excellent website with great information written by reliable scientists. It also has a well attended discussion forum as well.
Take some time today and visit.
