In this video keynote speaker Christian Nellemann encourages students participating in the Tropentag to make a difference.

During the Tropentag conference there will be 12 active student reporters running around, blogging, tweeting and taking pictures and video. They will introduce themselves to you below. Do not hesitate to approach them about interesting topics or if you want to share your thoughts or give feedback about the conference! We would also like to encourage you to comment on our blogs, tweets and facebook posts. If you like you can join the twitter conversation as well: just add #tropentag to your tweet!

We actively upload and post content on several websites, including Youtube, Flickr, and Twitter. Also be sure to visit the ETH Multimedia Portal for accessing all keynote presentations. Check it out!
