  1. I've been browsing online more than 3 hours today, yet I never found any interesting article

    like yours. It is pretty worth enough for me. In my opinion, if all website owners and bloggers made good content as you did, the web will be a

    lot more useful than ever before.

  4. Thank you, I have recently been searching for information about this


    subject for ages and yours is the best I have discovered so far.

  5. The end result is to describe as many species as possible with their connections in nature.
    And people are going to be finding out what is happening with the animals around us (I get lots of comments from school children, their teachers who give homework over nature)
    There are many sources that I have to check, especially the first to publish. But the vast majority are reliable websites are recognized for their work related to nature.
    I browse through your website, I knew they are going through a major economic crisis, but did not know exactly what was happening with the properties, is very unfair.
    I send greetings
