i'm james menendez. from here in the world newsroom, we send out correspondants to bring you the best stories from across the globe. in this week's programme... the culture clash in the amazon. we report on brazil's plans to build huge hydroelectric dams, which could change the world's biggest rainforest for ever. the impact of so many of these structures on the world's greatest river system, its environment and its people will be immense. a visit to china's mo5t polluted city. we find the worst winter smog in recent years i5 poisoning its people. it's like living under a cloud. the smog i5 harming my childrens' health. and the sounds of stonehenge. david sillitoe investigates how new technology is revealing more of the ancient stones' secrets.

what this new vr technology is offering is a chance to return back and see what this place used to look like in the past. to brazil's amazon rainforest now, where a battle is under way between its indigenous people and big business. the brazilian government i5 defending plans to build dozens of huge hydroelectric dams, which they say are vital to meet the country's energy needs. but environmentalists say the plans are a disaster for the amazon and will result in more deforestation and global warming. wyre davies has been to belo monte, the site of the first of the new so—called mega—dams to assess their impact. voiceover: from the heart of the planet's greatest rainforest, emerges one of the world's biggest civil engineering projects.

a monolithic monument to progress. the belo monte dam is brazil's answer to its growing energy needs. mired in controversy and allegations of corruption, the $18 billion dam partially blocks the xingu, a major amazon tributary and has flooded thousands of acres of rainforest. there's a human cost too. the local fishing has been decimated and thousands of riverside dwellers or riberenos, have lost their land and their livelihoods, forced into a completely alien, urban environment. we get angry, says this man, showing us his now worthless fishing licence. we see these corporations making millions from what used to be ours, he says, and we can't even use the river any more. building the dam brought hundreds ofjobs to the riverside town of altamira, but it also led to increasing deforestation and the permanent lo55 of many low—lying islands. supporters of hydropower admit mistakes were made. but they say the rivers and their energy are there to be harnessed for the greater good of brazil. i would definitely defend

the presence of hydro s! key technology in our portfolio of technologies. in the developed part of the world, almost 70% of the hydro potential has already been explored. in brazil, almost 70% of our hydro potential has not been explored yet. brazil says it wants to build at least 50 hydroelectric dams across the amazon. the government is saying it is clean, sustainable energy. but the impact of so many of these structures on the world's greatest river system, its environment and its people, will be immense. next in line for development, the tapajos. described as the most beautiful river in the amazon region and home to the munduruku indigenous people. the plan to build several

dams along its length would transform this wide, shallow river into a navigable water highway. but it would flood forests and islands used by the munduruku for centuries. tribal chiefs say they will resist any attempts to build dams on the river. clean energy and the promise ofjobs versus the rights of indigenous tribes. and whether to exploit or to protect this fragile eco5y5tem. wyre davies, bbc news, in the amazon. china is in the midst of its worst winter smog in recent years.

more than half of all of its cities are experiencing high levels of air pollution. visibility in beijing was reduced to less than 200 metres this week, increasing use of coal and current weather conditions have left a cloud of pollution over 3000 kilometres long across northern and central regions. john sudworth has travelled to the worst polluted city in china and sent us this report. voiceover: somewhere, underneath this murky gloom is a city of 10 million people. and, for the unfortunate residents of this city, this is normal. for the past 30 days, the average air quality in this city has measured as hazardous on the official scale. you can smell, even taste the coal dust in the air, the grim, tangible reality of this country's model of economic growth. and people have no choice but to live, eat and sleep in this toxic smog, 2a hours a day. it's like living under a cloud, this noodle seller tells me. the smog i5 harming my children's health. of course i want to leave,

this man says, but i can't afford to, and anyway, the whole country is polluted. it's not much of an exaggeration. 200 miles away, the pollution literally rolled into beijing earlier this week. and stayed. a toxic mix of coal dust from power stations and car exhaust, the smog now regularly blankets a huge swathe of northern china. and it's believed to cause more than a million premature deaths a year. translation: as a lung cancer doctor, i have seen an increase in patients in recent years, especially from heavily polluted areas. and when the smog gets worse, we see more kids with asthma. public concern has forced the chinese government to begin investing heavily

in renewable energy. those working in the sector believe china can clean up its air, just as wealthier, more developed economies once had to. i am pretty positive for china's future. actually, they don't need that much time for the science research. they don't need that much time to develop relevant technologies. so i think a lot of things are more ripe for us to make faster solutions. those solutions can't come fa5t enough for this city. fossil fuel5 may have lifted china's economy to ever greater heights, but they are poisoning its people. john sudworth, bbc news, china. studio: finally, there are many questions surrounding

the ancient stones circle of stonehenge. but might sound help in the search for answers? new technology is helping to recreate some of the strange acoustics of the mystical english site from thousands of years ago. much of the stone circle has been lost over the years, but as david sillitoe reports, the technology can even help us experience what the original prehistoric site might have looked like. eerie sounds. people have been coming here for at least 4000, 5000 years. so we are walking in the feet of history. when the wind blows, some people say they hear a strange hum. thomas hardy wrote about it in tess of the d'urbevilles. and dr rupert till is convinced the sound of stonehenge is part of its magic. wind blows eerily. you here between each beat a little echo as the sound leaves you, hits the stone and comes back to you here. —— you hear between each beat a little echo as the sound leaves you, hits the stone and comes back to you here. bang.

banging. the problem, this isjust a fragment of the sound people would have heard 4000 years ago. what this new vr technology is offering is a possibility, a chance to return back and see and also hear what this place used to look like in the past. we've kind of reconstructed it by rebuilding stonehenge digitally and then using architectural software to reconstruct the acoustics of the space, as it would have been when all the stones were here. so how different is the old sound to the sound we have today? if i tap this drum now, you hear a little bit of an echo. when all the stones are put in place, a much more powerful sense of enclosure, a slight reverberation, more echo and it changes more as you walk around. banging. and the reason he is convinced ancient people were interested

in sound is because of his work in caves in spain. hundreds of metres underground, they found ancient instruments and human marks on certain 5talactites. .. stalactites that are musical. i9, 20, 21, 22, 23, 24, 25. so today, it's just ruin beside a busy road. this, a chance to say goodbye to the 2ist—century and experience the lost sound of stonehenge. david sillitoe, bbc news. studio: intriguing stuff. that's all from reporters for this week. from me, james menendez, goodbye for now. wood turning much more but not for
