Tonight, one woman is taking on gender discrimination in the work place with a 16 million lawsuit. Ellen powell says she was denied promotion because she couldnt break into the boys club of the tech world. But her former company says she just didnt deserve it. Now shes opening up to our colleague and yahoo global anchor katie couric about why her fight to level the Playing Field isnt really personal at all. Reporter hbos Silicon Valley is set in a world that feels more like a frat house than a highstaked corporate jungle. Yes, a thousand times yes reporter it was this culture, seemingly glorified onscreen that was under examination when 45yearold ellen powell filed a 60 million gender Discrimination Suit against her former employer Kliner Perkins caufield and byers, a Venture Capital firm that has backed google twitter, and amazon. Youve got people who are used to not following rules and they dont know where the boundaries for behavior are. It works for them in one aspect of their careers. Reporter the lawsuit claimed among other allegations that there were unwanted sexual advances in the workplace. Retaliation against her after ending an affair with a married coworker. And uncomfortable conversation about pornography. Do you think the freewheeling, write the rules as you go along, kind of disruptive culture of a lot of tech firms, that while they may unleash creativity do you think that environment can conversely lead to bad behavior in the workplace . They take risks and they build product and people like and it they get rewarded for it. So its natural for them to bring it into other areas as well. Reporter the Company Claims it wasnt a boys club that got pao fired, but poor performance. A sense of entitlement and not being a team player. Pao disagrees and claims she didnt make senior partner because shes a woman. A woman is assumed to be the assistant, the junior person. Its just these Little Things that add up. They call it the death by a thousand cuts and youre just constantly trying to get that equal Playing Field but being taken out of it step by step. Reporter she says she was often left out of social engagements which brought her male colleagues closer because, as pao alleges one colleague said, women kill the buzz. Lets talk about the sort of offhour social activities. Like dinners or ski trips or golf outings. Is that where a lot of the business is actually done . Where a lot of the relationships are actually built and established . And how does that affect people who are maybe excluded from those activities . Youre forming closer relationships, youre having discussions about business in these different events. And you may be actually resolving problems or getting somebody to say, okay i want to do this transaction, i want to have this project move forward. Reporter her trial played out like a reallife soap opera set in Silicon Valley. The details of her marriage to wall street executive Buddy Fletcher put under a microscope. He sued the board of the dakota a tony new york city Apartment Building where john lennon once lived, for Racial Discrimination after it didnt approve the purchase of an additional apartment. The board claims it had nothing to do with race but alleged financial troubles. Fletcher declined comment for nightlines story. Some have questioned the timing and motivation of your whole case your husband was having legal and financial troubles, including a bankruptcy surrounding the hedge fund he ran. Some stories have suggested that he might be the driving force behind this. Others have said he warned you this would ruin your career. How would you describe his role in all this . I cant talk about the case and i would rather not talk about my husband. Do you think in some ways even if you cant discuss it, its relevant . I think this is a really hard issue. And people are very comfortable attacking the person who raises these issues with whatever they can find. And its often not very pretty. In the end, a jury of six men and six women sided with paos former employer. When it comes to your situation, people have said you know, there was no legal merit to your complaints. And is this something that can be proven legally . In other words, are there often subtle examples of this that may not be illegal, but they may be inappropriate or they may create an environment that is not helpful to women and minorities . So i dont really want to talk about the legalities of my case or general i think people have to think about what is fair, what is right. Are women succeeding at the rates they should be . Are minorities succeeding at the rates they should be . If you look at the numbers and hear peoples experiences, the answer is no. Reporter despite receiving fan mail and messages of support from around the world, paos lawsuit had its critics. The idea that she was highly qualified and still fired just does not make sense. Reporter Heather Mcdonald wrote a scathing op ed in the wall street journal about paos case. In fact, ellen pao was given advantages and a leg up that male comparable employees at Kliner Perkins were not given. Some of those negative comments and some of the critics i think might say that women play the gender card when the truth is they just arent that good. So when people accuse you of just, hey, she couldnt cut it and shes just crying foul regarding gender. Whats your response to that . I cant really talk about my case. So i can tell you that its from a broader perspective, its a harder issue for people to really confront. Its either society has this problem and its hard to fix, or this woman has a problem and lets just ignore it. Reporter pao may have lost this battle but shes not raising a white flag yet in her case against kliner. Is the road ending here for you in terms of your Legal Recourse . Where does that stand . We are not talking about it. Were still in the midst of making some decisions. About whether you will in fact appeal the case . Yes. And were not talking about it. Our thanks to katie couric.

Reporter this corner of northern uganda, where the river nile cuts through lush rain forest and golden savannah, is known as the pearl of africa. A nickname proudly reclaimed by mercy falls National Park even after decades embroiled in environmental crisis. Its been a long sevenhour car ride across two continents. It is not an easy place to get to. But on the horizon, a creeping new challenge. One that again threatens the park and its wildlife. Clouding its future in uncertainty. Are you excited to be here . Very excited. Reporter weve traveled here with shabani. Im resting up to be excited. Were seeing the nile. Its amazing to see the nile.

Reporter this pairing and the cub it may produce points to a Bright Future here when it was almost lost forever. During the brutal and violent reign of former president iddy idi amin, the park became lawless. Hippos and buffaloes, up to 95 was lost. 95 during that time . Lost due to poaching. Due to poaching . Reporter he saw it firsthand. He now manages the National Park for the ugandan wildlife authority. Oh my lord. Look at this. This is just this is a container full of poaching equipment. Put it on the neck, squeeze like a hangman. This is like a land mine. Reporter since tom took over things have started to change. Two years ago, we were getting when one patrolman would come back with 50. 50 . But now you can come back with none. That means the antipoaching efforts is paying off. Reporter in part with the support of groups like the uganda conservation foundation. Weve managed to get rid of over 8,000 snares in one year. Reporter michael works closely with the uwa to ensure pictures like these, filmed by National Geographic for a special about the nile images of elephants and lions caught in snares, become a thing of the past. After 30, 40 years of real trouble, i mean you really cant get much more trouble than the idi amin era then joseph coney, is now recovering. Its one of the most spectacular, heartwarming stories. Reporter driving through the park today this troubled past is nearly invisible. Signs of a future threat are hidden in plain sight. There are oil wells in this park . Yeah. Reporter the promise of a fortune. Locked underground, drawing Major InternationalOil Companies to the region. What were seeing here, pristine, untouched park could change dramatically . We dont know. Maybe. They are promising that they will do their best to make sure that the impact is minimized. This is how it looks at the moment. Reporter most of the construction in the park so far just for Oil Exploration, has been temporarily restored. We are looking at one of the tracks leading to the wells. You can tell because all of those plants are sort of in rows. Exactly. If you can see that behind me, theres a darker patch of grass over there. And thats where theyve done some exploratory drilling for oil. Reporter when Development Moves ahead as planned the wells will be impossible to conceal and the Environmental Impact impossible to predict. When you first heard that Oil Exploration would be done in the park, what was your reaction . I think i was like, oh my god. I thought it was probably some it was going to be very bad. Reporter those fears have faded, replaced by optimism. You think the two, conservation and oil can coexist . We want it to coexist. We want it we are doing Everything Possible to make it coexist. Its a paradise we have to take very good care of. Reporter a message echoed in the corporate videos of the oil joint. This is a big budget. The expenditure will be the size of the gdp of the country. Reporter promising careful oversight and very real potential for the local economy. Once we go in we need to ensure that we have left the environment pretty much the way that we saw it in the first place. Reporter but he believes the Oil Companies should leave the park not just as they found it but better off. The challenge is can we get those companies and the government to get that to happen . Ive not seen evidence of it yet. Reporter a discovery that could be ugandas economic salvation or some fear its ecological ruin. Either way the stakes couldnt be higher.
