This reminds me of a great exhibit at the Museum of Natural History in NYC.
I only know about this because of XKCD, but it's still pretty awesome...
If you've got a lifetime to kill, this seems like it could be a nice place to start.
"A common use of Flickr is to find photos. But what about finding a new species of insect? Insect biosystematist Dr. Shaun Winterton discovered a photo on Flickr of a green lacewing taken by Hock Ping Guek (known as Kurt on Flickr). The insect was not identifiable as a known species to Winterton, and after collaborating with the photographer, a specimen was collected in the Malaysian rainforest. Further examination showed that this indeed was a new species. The discoverers named it Semachrysa jade. The discovery was published in ZooKeys and the abstract reads: A charismatic new species of green lacewing discovered in Malaysia (Neuroptera, Chrysopidae): the confluence of citizen scientist, online image database and cybertaxonomy."
There's some theory that suggests that combining these sets of plants can work together to clean air very effectively. And I think it's not totally crap.
Did this hike today to a bunch of natural hotpots. It was pretty amazing.
