Wildlife dies off. Welcome back to our viewers in the United States and around the world. Im George Howell. This is cnn, and we begin in the u. S. State of new jersey where the latest ebola scare took place this weekend. All 255 passengers on a plane that landed in newark from belgium have now been released from quarantine. They were detained because a man began vomitityi itityin itit ii. It tooks hou hours before the p were able to leave the airport. Instead of seeing the process from the very beginning we just let us go out of the plane. And then after the plane we had to wait at the passport c concontrco control and wait for the luggage. No information, no reason why we are to wait like that. What a scary situation for people on that plane. Now in the state of texas, the first person diagnosed with ebola in the u. S. Is now in Critical Condition. Thomas duncan is hospitalized. He was diagnosed last tuesday, about a week after he traveled from liberia. State officials there say nine people who came into contact with him are showing no symptoms at this point. Another 40 people are being monitored but are considered lowrisk. With concerns now growing in the u. S. About ebola, the director for the centers for Disease Control and prevention spoke about it. We do have to realize that we are all connected. And although we might wish we could seal ourselves off from the world, there are americans who have the right of return. There are many other people who have the right to enter into this country. And that were not going to be able to get to zero risk, no matter what we do, unless, and until we control the outbreak in west africa. The current Ebola Outbreak has killed more than 3400 people in west africa so far. The u. S. Says it could now send up to 4,000 troops to help fight the virus where it is most deadly. Cnns Barbara Starr has the story. Reporter with 3,000 troops already tapped to head to ebolaravaged west africa, cnn has learned the u. S. Military is increasing its fight against the deadly disease. Hundreds more troops are being added to help the affected countries contain and control ebola. Its america, our doctors, our scientists, our knowhow that leads the fight to control the epidemic in west africa. Reporter approximately 200 u. S. Troops are already in liberia. Chuck hagel has signed orders for another 700 from the 101st Airborne Division to head to africa in coming days to staff a command headquarters. 700 more Army Engineers will be going to help build and advise on mobile hospitals. Were standing up a Field Hospital and treatment units and will be training thousands of health workers. Reporter even before most have left the u. S. Military officials tell cnn the pentagon is considering drastic measures to ensure they dont come back to u. S. Shores with the disease. We are working with experts right now on this. Reporter that could include forced isolation four 21 days, the incubation period for troops that may have come in contact with the disease. All troops will be monitored daily for symptoms, and all Service Members will face increased monitoring for those 21 days before they are allowed to return to the u. S. This is a complex emergency beyond a Public Health crisis which has security, dimdimensio. Reporter they will take all their own supplies, food, water, fuel, everything they need for a sixmonth deployment. The other big story we are following, the fight against isis. Kurdish forces say three are holding back militants in the syrian town of kobani. Isis controls the southwestern corner of the city, but forces held off further advances. A Human Rights Group says coalition ash strikes killed at least 35 isis extremists on saturday including five in the town of kobani. Our phil black is watching events and joins us live now where you can see this playing out, i believe. Reporter yeah, i just took you through what we are seeing here this morning. Were on the sturkish side of te border, you should be seeing what is the southeastern corner of kobani. That is the position we are seeing repeated incoming fire, heavy shelling, and it is around that position, kurdish officials tell us there are a number of isis tanks, maneuvering and repeatedly firing in to that corner. We are hearing and witnessing a constant heavy shelling into that pocket of the city. Now just above that pocket of the city you can make out the hill above kobani. That is, according to everything that were hearing from inside the city, the main thrust of the isis advance. It is this key, very strategic position that isis is trying to take. That piece of high ground overlooking kobani. Theyve tried to advance on that position repeatedly up the Southern Side of the hill over the last 30 hours or so. And up until this point, the kurdish have been able to repel them. That said, the kurdish fighters fully expect isis to make it into the city in the not too distant future. They are getting ready for bloody, urban battle. They believe in those situations they will have something of a tactical advantage. It is taking isis a little longer to get into that position. A factor there could be a recent spike in Coalition Air strikes. Saturday saw a number of strikes around the east and southeast, targeting isis artillery, armored vehicles, as well as fighting units as well, quite effectively we are told by the kurdish fighters still inside the city. They tell us there were more Coalition Air strikes overnight yet to be confirmed by the United States. The kurdish fighters on the ground do not believe those air strikes were as effective as those that knocked out the isis positions on saturday, george. Phil, there in turkey, there are people who want to cross the border and join the fight against isis, but what is the latest response or indication from the turkish government about allowing them to do so . Reporter just hearing very large shelling blast behind me, george, just to that pocket we were discussing a moment ago. Youre right, because there is a strong ethnic kurdish population on the turkish side of the border as well. Were told there has been a lot of movement from local kursd he kurds crossing over to try to help. Whenever large numbers of kurds have assembled, Turkish Security fours have effectively blocked their path, even going so far as to use water cannon and tear gas to disperse them. It is a National Holiday here in turkey, at the moment there are large numbers of people who are traveling to this border area to watch, to try to see what is going on on the other side, to cheer on for their, the kurdish, the fellow kurds on the other side of the border as well. But we understand there are a number of people who regularly try to cross over into kobani into the Syrian Kurdish territory to join the fight there as well. And we can see in the distance there behind you some smoke from what you were pointing to. Phil black on the syria turkey border we appreciate your reporting from the region. The parents of american aid worker peter kassig are pleading with isis to release their son. He was kidnapped last october and isis says he will be next, the next hostage to be killed. In a june video posted on saturday, kassigs parents urged his captors to release their son. Please know that we are all praying for you and your safe return. Most of all, know that we love you. And our hearts ache for you to be granted your freedom so we can hug you again and then set you free to continue the life you have chosen. The life of service to those in greatest need. Kassig founded a charity just two years ago to help syrians who were fleeing from the countrys civil war. His parents say he converted to islam after being captured. The threat against kassigs life was made at the end of a video showing alan henning. Hennings home is reacting to the aid workers death. By joining the u. S. Air strikes we handed alan and many other hostages a death sentence. We will have a closer look at the anger and sadness surrounding hennings murder coming up in less than 30 minutes. Still ahead on cnn, prodemocracy demonstrators in hong kong are approaching a deadline to clear out the streets, but will they do it . A live report is next. Plus an ancient culture at risk of a modern decision. The fear facing many bedouins in the west bank. Sisters wedding. Well its only 100 calories, so youll be ready for that dress. Uhhuh. You dont love the dress . I love my sister. 40 flavors. 100 calories or less. We have seen this now for the past several days, prodemocracy protesters filling the streets in the evening to protest. We take you to hong kong. The top official wants these crowds to disperse by monday morning and for things to get back to normal. But the students have no intention of backing down. Lets go to hong kong with the very latest on whats happening. Reporter the clock is certainly ticking, and its ticking toward a monday, local timedeadline. That is when the government says it will set a time for these streets to be cleared. What it exactly is planning, theyre not saying so much. We did just get a statement from the president of Hong Kong University urging, urging students of its university to clear out of here, saying that they are concerned for the students safety. But also, were seeing movement on both sides. Both the protest side as well as the government side. It looks like theyre open to talk. But they havent met yet, and those concessions that each side is demanding havent happened as of yet. So, george, were still watching to see what is going to happen overnight, these overnight hours absolutely critical as we look to that monday deadline. Any sign of police at this point . Police presence . Reporter yeah, we havent seen any Police Presence here. But we have seen a significant showing of rescue vehicles. Some six fire trucks as well as a number of fire personnel. The reason for that is because for the last few hours theres been a man standing on the edge. Its ground, todays protests to a halt. You can see all these people behind my looking up at this man. We dont know his intentions. He has been standing there for several hours demanding that he talk to the student leaders of this protest. Joining us there from hong kong with the very latest. Thank you for keeping watch of it and we appreciate your reporting there. Typhoon phanfone is skirting japan right now. When will it get there . Good question. Weve got another few hours before this eye wall actually makes its way onto land. And that is the also forecasted track by the joint typhoon warning center. Now the latest on this storm actually indicates that it has weakened somewhat, about 20 Kilometers Per Hour weaker from what it was about six hours ago. Now this is the latest satellite imagery, and it has fineally taken that much anticipated eastern direction and it is picking this storm up and pushing it on very, very quickly. In fact, you can see 24 kilometer per hour to the north and east. This is a live webcam from tokyo. Its a bit tricky to see, but the sun has just set. And the rain also also settled in. And this forecast looks to be rather tricky, especially into your monday morning commute. Were expecting wind gusts around typhoon strength. Especially around tokyo, you want to take caution with that. It has been an extremely cautious start to the japanese grand prix in japan. The caution vehicle actually leading the way for much of the race. Of course the race is over at the moment. But there were several rain delays associated with typhoon phanfone. And the big question now is how are they going to pack up these vehicles and get them to sochi, russia, which is the location of next weekends formula one event, especially with windy and rainy conditions in the forecast. Were expecting the wet weather to continue to impact that region. And if this is any sign of things to come, 224 millimeters. In some locations, tokyo, youll exceed 200 millimeters in the next 24 hours. Ive timed out our forecast winds to show you how strong it will be across this region monday morning. So do take care if youre located in this region. Back to you. Authorities are searching for a group of missing students in mexico and have found a horrific discovery. Theyve unearthed mass graves in one of the countrys most violent states. The identity of the bodies are unclear, but dna tests are now being conducted. The students disappeared after a Deadly Police shooting weeks ago. Police say al shabab has abandoned its last major stronghold. Military commanders say al shabab pulled out of the city on late saturday after somali and African Union forces spent three days camped out on the outskirts of the town. The withdrawal came hours after the coastal city was recaptured when shabaab fighters left the area. The worlds wildlife has suffered but the impact is felt well beyond the animal kingdom. And later, transparent proves to be a revolutionary new tv show. And a father coming out as transgender is one of the unique angles of the story. Ring ring progresso you soup people have my kids loving vegetables. Well vegetables. Shh taste better in our savory broth. Vegetables . No. Soup oh soup loaded with vegetables. Packed with taste. Welcome back. The worlds wildlife is in stark decline. More than half of wild animals populations have disappeared in just 40 years. That is according to a Study Released by the World Wildlife fund. Reporter the state of the planets wildlife has been laid bare. A new report says Global Wildlife population have more than halved since 1970. Wwf says populations of mammals, birds, amphibians and fish and reptiles have declined on average by 52 . Then it goes on to say animals living in rivers are the worst affected with 77 disappearing in that 40 year period. That entire decline is down to us, human activity and our demands, be it through habitat loss, overfishing and hunting. Now the full world life loss seems to be worst in africa. But the most affected is latin america with 83 of wildlife lost in those 40 years. Now in terms of the animals impacted, the wwf says many of them are currently facing a double whammy. Its definitely the animals worst threatened. A perfect example are forest el vants which live in central africa. And they have been hit badly by deforestation. Plus theyre being targeted for their ivory. Whereas, if you took the example of tigers, tigers have gone down from about 100,000 to only 3,200 tigers left on the planet. But their habitats, there are large tracts of habitats they could expand into, but its the poaching thats affecting it. Reporter and with the human population expected to grow, there are fears that the planets wildlife and ecosystem will only be damaged further. Isa suarez, london. The decline in wildlife has been blamed on the most dangerous inhabitants, human beings. Earlier, Natalie Allen spoke with an expert who said humans shouldnt underestimate how much they need nature. I think the greatest emphasis is on over exploitation. Thats really our consumption of wildlife for food and, of course, that supports 15 of the jobs on our planet. So this is a huge industry, critical lay important as a source of livelihoods and for the diets of billions of people. Thats the primary driver of this decline. But we also have habitat loss. We have other types of changes to the environment, including the toxins and other things that we put out there, along with the spread of Invasive Species that can dramatically alter and impact natural communities. Reporter its at stake if this decline continues . So this really isnt just an issue about, you know, tree huggers or other things. This is about the fate of our economies. These are big issues about security. You know, as people become more and more desperate, as they lose the Critical Resources on which their lively hoods depend, they often resort to violence. Theyre going to fight for access to wildlife as it becomes more and more scarce. So there are all sorts of big consequences for this, and we need to take note. Reporter and is the exploding population also contributing . Population growth is certainly contributing to this, and what it means to some in many areas in what used to be an amount of wildlife harvest, lets say a fishery or bushing it, which is wildlife on land, what used to be a sustainable harvest or harvest enough to support a community is no longer enough. So that leads to higher level and a demand for labor. And that leads to human injustice such as Human Trafficking or use of child labor. So what can we do about it . So rather than saying hey, youre not doing enough as an individual, what the index does well is really pointing towards Big Government action, big industry action and trying to understand more about the policies that have promoted a freeforall on our oceans and a freeforall on our lakes and a freeforall on a lot of our terrestrial areas and our forests and savannahs. And really, what that means as individuals is being more active. We had hundreds of thousands of people show up in new york a couple weeks ago to march in a call for more Political Action on climate change. And we need similar activism. Certainly an important story. Still ahead here on cnn, Muslim Leaders come together in manchester, england to condemn the murder of native Sun Alan Henning at the hands of isis. And israel at odds with the United Nations over the relocation of bedouin herders. Its a mass forcible transfer, which is a violation of International Law of the fourth geneva convention. This is all within the west bank and within a few kilometers this way and that way. We will get more on this debate and hear from one of the bedouin whose lively hood depends on it. Its after this break on cnn. There comes a time in everyones life when you want more. Like a new meticulously engin
