High preessure water hoses and blasted out. And its not just the land. People are stepping into mercury. Im philtorres im an entomologist ive conducted Extensive Research in this rain forest so this story is personal. It really pains me to see this. Marita davidison is a biologist specilaizing in ecologyand evolution now she shows us the high tech tools that are exposing what even the eye cant see. So where its blood red thats where the mercury polution is most intense. Well share our findings with Lindsay Moran shes an ex cia anaylist. Thats our team, everything weve been seeing. Its for this. Now lets do some science. Hey guys welcome to techknow im phil torres joined by Lindsay Moran and Marita Davidson. This upcoming episode is an important one to me it takes place in peru where ive done alot of
Planet. All the damage microscopic agent. Lindsay moran is exc. I. A. , shes about to join them. Entering a biolab. Sorry, we cannot confirm your identity concern . What is going to be like ebola, but we havent seen it yet. Dr Charlotte Mcshane is a mechanical engineer. Tonight what she learnt about tornados. Phil torres. Im phil torres. m an entomologist. Thats hour team, nout lets do some science. Hey, guys, welcome to techknow, joined by dr ross shimabuku, and lindsay moran. Microscopic things have been making news. Viruses. Take ebola it caught america offguard. In some places we overreacted and in other places we doesnt do enough. Theres a lot of scare around ebola, because we dont know much about it, compared to measles. Which is also a hot topic. When we think of diseases we tend to think of containment.

Ill share it with a biologist. Thats our team. Now lets do some science. Hey, guys, welcome to techknow. You guys know, ive spent a lot of in the jungles. I do my research in the tropics and usually im looking at spiders and butterflies. But this time i went down to costa rica to look at something different. We know there are a lot of scientific issues out there protecting our rain forest is one of them certainly but maybe its not quite high enough on the list. Because were realizing now that rain forests are doing Incredible Services for us in society. And theyre doing them for free. Completely for free. We dont usually think about ecosystems like rain forests providing fundamental services. It takes so much to keep new york running, so many systems, the rain forest is so much more complex. What
