Does that sound interesting, fascinating and exciting? For the first time we can scientifically observe, record and chart the progress of this event as it happens, because it is happening in the here and now.
But wait a minute! if it is happening now doesn't that mean we are a part of it ? Yes it does, and if we are lucky humans just might survive as one of the few remaining species, but do not count on it.

Humans do not know for sure how many species of fauna and flora we share the planet with but it is known to be millions. Although there are about 2 million species known to science it is estimated that there could be 5 to 15 million but could be as much as 100 million species altogether. Clearly there is a huge gap in our knowledge. Nevertheless it does show there is great biodiversity of life on the planet which biologists believe to be essential to maintain a healthy environment for all living organisms.
Some of these like bacteria and spores we can only see with a microscope. Many of the larger ones we see, we interact with them, we can count and study them and of course there are the ones we like, the cuddly, cute funny ones and the one that taste good. We have learned how to breed and domesticate animals and plants and keep them in such numbers that they seem safe from any threat of extinction. For example, cattle, sheep and chickens do not appear to be in danger of extinction as we breed them in their millions, but their existence depends on us. Nevertheless, the situation for many wild species of flora and fauna in the wild is becoming increasingly desperate. Read more
