Here are some interesting facts about earthworms:
- They have no immune system…or teeth
- The more rotten their food is, the better
- They are the most numerous animals on earth
- They lay cocoons every day or so
- Earthworms create, purify and sanitise soil
OK, this is interesting but nothing I can’t get from Wikipedia.
I’m in two minds about this presentation. I enjoyed it thoroughly but to me it didn’t seem to fit in with the theme of the conference…community upliftment. Yes, earthworms are a great source of organic fertiliser that increase crop yields and are good for the environment.
But I was under the impression that presenters at TEDx must have done something to improve their small corner of the world. Professor Eksteen has studied earthworms and clearly knows a lot about them. He’s presented some interesting facts about how earthworms can be good for agriculture, but hasn’t done anything besides be an academic who studies earthworms. Or maybe I missed something…?
As I said, this was interesting, but was it an idea worth spreading?
