follows a global outcry over fires ravaging parts of the amazon rain forest. most have been set by farmers and ranchers. in tonight's eye on earth, manuel bojorquez hears their side of the story. >> reporter: it may be hard to believe that all this was once lush rain forest. these lonely trees, the only reminders of the canopy that stood here. it's now a 2200-acre cattle ranch managed by alberto. hard work, he told me. but in rural brazil, a god send. i don't have the giuliani indication to get education to get a job in any industry so this is my livelihood and business is good. >> reporter: it's gone up, the demand? >> si, si. >> reporter: demand from china has brazil's beef industry booming. it's the number one exporter in the world, but at a cost. by some estimates, about 80% of the deforestation happening in

the amazon is to make way for cattle ranches like this one. >> fake science. >> reporter: fake science? president of the area's agricultural federation is in lockstep with brazilian president jair bolsonaro who wants to open more of the amazon for business. if this continues at this rate, is it possible to save the amazon? [ speaking foreign language ] >> reporter: it's impossible to destroy it, really? he argues fires are normal during the dry season and the current outrage around the world is politically motivated. [ speaking foreign language ] >> reporter: so you're not looking to destroy, you're looking to give people opportunity, economic opportunity? >> yeah. >> reporter: scientists call that view dangerously misguided, and if nothing changes, they say, the balance between human activity and protecting the amazon is rapidly tipping against the rain forest. manuel bojorquez, cbsonco, braz. >> still ahead, with red light

distracted driving is blamed for driving up deaths at red lights to a 10-year high. and as kris van cleave shows, technology to curb this problem is proving controversial. >> reporter: this lexus runs a red light, plowing into an s.u.v. and killing its driver. a new study from a.a.a. finds red light deaths have surged, up 28% since 2012. >> the problem is, is drivers are distracted. they're impatient. and they're reckless. >> reporter: research shows red light cameras, which catch drivers in the act and mail them a ticket, cut fatal crashes by 14% and red light running by 21%. but outraged drivers call it "policing for profit." >> i think it's about the money. >> reporter: kelley cannon led the charge in texas to ban red light cameras this summer, the eighth state to do so. >> i call it government-sanctioned extortion. >> reporter: new york city was the first to use red light cameras and now is increasing its speed cameras 10-fold to

britain just suffered through its second brutal heat wave of the summer. elizabeth palmer shows us it's got some people down.

>> reporter: on the hottest day of the year in london, the queen's guards are quick-marching in 100-degree heat, and every one of them is hoping not to do this: all soldiers are prone to fainting, even the u.s. marines. in fact, it's such a problem, that the british army is doing research on how to prevent it. major ian parsons is an army cardiologist. >> standing for prolonged periods of time still, that puts you at increased risk. now, you add in heat to that, that's a further risk. >> reporter: talk about adding heat, take a look at this uniform: woolen trousers, a heavy, snug jacket done all the way up; and to top it all off... when are you going to put that on? ooh, all right. that's bear fur. frankly, it's a wonder this doesn't happen more often. so how do these soldiers prepare?

f drate, eat your scoff in the morning, and wiggle your toes, you're fine. >> reporter: translation: drink lots of water, eat your breakfast and-- yes, that's right-- wiggle your toes. it keeps the blood flowing, and it doesn't show. the army's research suggests that eating up to four times more salt than normal also helps. and so does exercising in the heat, which could be good advice for all kinds of people. >> but, like, policemen, people exposed to lots of heat, like firefighters, or people just on packed commuter trains, packed buses who don't have seats. >> reporter: if the army does work out how to keep the queen's guards upright, we all stand to benefit. elizabeth palmer, cbs news, london. >> and that's the overnight news for this friday. for some of you the news continues. for others, check back later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm john dickerson. two

>> announcer: this is the "cbs overnight news." >> welcome to the overnight news. i'm nikki battiste. hurricane dorian continues to grow in the warm waters of the atlantic. it's still days away from expected landfall in florida, possibly as a powerful category 4 storm. a lot of florida residents are bracing for the worst, but others say they've heard this song before. lonnie quinn sorts it out in your overnight news forecast. >> reporter: this could potentially be a top 10 storm in florida throughout its history. if you take a peek it's still a category 1. winds haven't changed, it's

moving through the northwest 13 miles per hour. it's part of what we're watching. number one, there is super heated water in front of this storm. you need water temperatures of 79 degrees to maintain the hurricane. if it's warmer than that, that storm can really grow. this water is going to travel over 85 to 90 degrees. all right. so this is why we think it's going to get much larger than it is. also that forward speed slows down. right now we just said it's moving 13 miles per hour. by the time this gets close to affecting land, it's going to be moving between 4 and 6 miles per hour. again, the slower it moves the more chance it gets to grow over that warm water and the longer it affects a certain area. inland flooding could be a big deal. if you take a peek at the high pressure that's going to steer this, we know it's going to push it toward the southeastern portion of t.swh iin makwhy we from savannah, georgia, to the keys of florida because look at the spaghetti models. they're all over the place. want to point this out. this is the european model right here, having it come into south

florida. then it buzz saws right up the coast line constantly pushing on shore, a storm surge a big problem, huge problem potentially with this storm. >> the governor of florida isn't taking any chances. he's declared a state of emergency. david begnaud is in cocoa beach with the details of the preparations. >> reporter: the line to get sand bags has been close to a half mile today. people have been waiting -- how long have you been here ma'am? >> since 11:00. >> reporter: 11 hours. one woman had been here eight hours. the sand bags the inmates from the county jail will fill for you and you're on your way. this is not the only line, there are several dozen. we got a time lapse today as we drove what seemed like ten city blocks where people were stopped trying to get sand bags. met a woman named jamie, her daughter mackenzie, a toddler in the back seat. had been there with mom for six hours in a car seat while she waited to get sand bags. it's not only sand people are trying to get. it's water, food and fuel.

there are lines outside of places like cost co-sam's and walmart. some stores are telling people you get four cases of water per family, that's it. the governor here in florida said there is a ton of fuel. we are seeing fuel lines. nothing really out of hand. speaking of the governor, he has declared a state of emergency for every single county in florida and he said today i did that because the cone of uncertainty is so wide we don't know if it's going to hit miami or jacksonville or somewhere in between. >> former fbi director james comey will not face charges for sharing memos of his meetings with president trump with the press. comey claims he's been vindicated. president trump doesn't see it that way. paula reid has the story. >> mr. president, your reaction to james comey, sir. >> reporter: the president wouldn't comment on camera about the comey report, but earlier today tweeted, he should be ashamed of himself. comey was investigated for memos he wrote about interactions with president trump after the 2016 election. in one shortly after the

inauguration, comey wrote mr. trump told him he needed loyalty and expected loyalty. then after mr. trump fired him in may 2017, comey asked a friend to give the memos to new york times. >> i asked him to because i thought that might prompt the appointment of a special counsel. >> reporter: the tactic worked. robert mueller was appointed special counsel. but today the inspector general said comey had several other lawful options available to him and that his actions set a dangerous example. the i.g. criticized comey for keeping and leaking the memos, but wrote that while they did contain some classified material, there was no evidence that comey or his attorney released any of the classified information to the press. comey declared victory, tweeting, to all those who spent two years talking about me going to jail, ask yourselves why you still trust people who gave you bad info for so long, including the president. but comey may not be totally clear just yet.

the inspector general is expected to release another report about the origins of the russia investigation, and attorney general william barr has tapped the u.s. attorney in connecticut to handle any criminal conduct that's uncovered. >> the immigration service is now taking aim at migrant children here in the united states for life-saving medical treatment. errol barnett spoke to one young patient who faces deportation. >> reporter: this is how 16-year-old jonathan sanchez stays alive. a vibrating vest, nebulizer and special medication helping him battle cystic fibrosis. the life-threatening disorder damaging his lungs and digestive system. it also claimed the life of his sister samantha back in honduras when she was just six months old.

>> announcer: this is the "cbs overnight news." >> welcome back to the overnight news. i'm nikki battiste. the growing popularity of doorbell cameras is sparking new concerns over privacy. turns out amazon's ring camera can be accessed by the local police department. jamie yuccas has the details. >> somebody is there and they're breaking into my house. >> reporter: ring's home surveillance cameras have captured crooks in the act. >> hey, man. don't do it. >> reporter: everything from home break-ins. >> what are you doing? >> reporter: to stolen packages. >> you can stay informed with alerts from your community. >> reporter: ring also offers the neighbors app which lets customers know when and where a

crime happens in their area. it works in conjunction with the so-called neighbors portal, now used by some 400 law enforcement agencies, to request customer video that might help their investigations. ring c.e.o. jamie. >> my goal would be to have every law enforcement agent si on the police portal that helps all communities come together to make things safer. >> we're going to see a growing sense of people becoming informants on neighbors and our neighborhoods. >> reporter: andrew ferguson is author of the rise of big data policing. >> there are going to be potential who gets targeted in the neighborhood apps. that can be troubling because there could be a police response and that could impact someone's liberty, someone's lives. >> reporter: ring says its customers have complete control over their videos and can choose to give consent to a law enforcement request for access. >> the ring customer will see a request come up. they can either accept the request or they can opt out of

that request and all future requests, and the police will never see if they have done that. >> reporter: but privacy advocates worry that customers might not always have the final say. >> yes, we have a choice. sometimes, but it's very easy for police to get a search warrant for that same footage if they believe a crime has occurred. >> i can tell you we'll always follow the laws, but we will always fight for our customers something great from mr. clean. stop struggling to clean tough messes with sprays. try clean freak!

the new york city marathon is just over two months away. about 50,000 runners will take to the streets along with dozens of athletes in wheelchairs, and even a couple of blind contestants. how does a blind person run a marathon? lee cowan got a lesson. >> reporter: like many athletes, simon loves chasing that runner's high. >> i still get a real buzz from doing it. >> reporter: do you? >> oh, yeah, yeah, yeah, really do. >> reporter: he trains on this path near his home in done castor, a village in north central england. but to really stretch his legs, sharing the solitude of his run with passing traffic. now, any jogger knows that that can be a pretty dangerous proposition. but for simon, it's especially so. so what do i look like you to now? >> i don't see anything as i look at you. nothing, just a wash of light,

>> reporter: yes, simon wheat croft is completely blind. >> round the corner. so, i was born with a genetic disorder where the vision deteriorates over time. >> reporter: he was diagnosed with this rare condition when he was about 11. for a while he could discern shapes and recognize faces. but by age 27, it was all gone. how did you handle that at first? >> at first i didn't handle it very well at all, you know. i was still going to move around on a daily basis, but there's nothing you can do. your vision is slipping away. you can't stop that. >> reporter: it really hit home the day he decided to propose. in 2009, he made his way to the u.s. with the hopes of popping the question to his girlfriend, high atop halfdome in yosemite national park. but halfway in he realized the

hike was more than he could handle. so what were you thinking, knowing you had to turn back? >> i was incredibly angry, you know, and i was faced with an obstacle, the only reason is because i couldn't see. >> reporter: he did end up proposing in the shadow of halfdome instead of on top of it. but what he also vowed was he would never let his lack of sight get in the way of his mobility again. >> in life we all seek control of our own destiny. i felt like i needed to readjust to gain control and learn to overcome these obstacles. >> reporter: turns out simon is a bit of an over achiever. he's now run the new york city marathon three times. the boston marathon, also three times. and he's even attempted two 100-mile plus ultra marathons. >> this gives us the vibration feedback. >> reporter: all while testing different pieces of technology he hopes one day --

>> field road. >> reporter: will help a quarter of a billion people around the world who are visually impaired either walk, hike or, yes, run without the help of a guide. >> i wanted to prove that mobility could be mastered because mobility is hard for a bliepd person. it seemed like the only viable decision was to run alone. >> reporter: were you a runner before? >> no. >> reporter: so just how does he do it? well, he started out slow. first on this soccer field, running back and forth between the goal posts. to guide him, he tried out an app called run keeper by ibm that uses voice commands to tell a runner time and distance. when you were running back and forth, nobody could tell you couldn't see. >> no. even today i still don't particularly wear anything that says i'm blind. >> reporter: soon he upped it a notch to a stretch of road. about a third of a mile long, it was closed to traffic. >> i just ran up and down, up and down.

>> reporter: how many times did do that? >> i peaked at ten laps of it. >> reporter: his confidence grew, but so did simon's boredom. one day, almost without thinking, simon left that closed road and ran into traffic. he couldn't see the cars, but he could hear them and reasoned if they got too close, they'd just drive around him, or so he hoped. >> i was definitely overcoming emotion, i did burst into tears. wow, i've really broken through a barrier there. >> reporter: he showed us how he stays near the curb on the double yellow line. he says he can actually feel the thickness of the paint through his sneakers. so right now as we're walking you're using the line. >> i'm trying to feel the lines and feel one difference between 1 foot and the other. the feeling right now for the right feels very different from the left foot. it's that difference that helps to guide. >> reporter: did the noise of the cars ever give you -- >> no, i could hear them coming

from a far distance away. so what i would do is basically just hear -- i mean, running this way, and i'd be listening tort cars coming that way to time crossing the road across there. >> reporter: the more we talked, the easier it became to forget that everything simon is doing is in the dark. >> we're dipping down, dipping down, step. >> reporter: simon tried video once of what it would look like for him. it's pretty unnerving watching metal lamp posts and street posts go flying by knowing he can't see any of them coming. but he's memorized where each and every one of those obstacles is. >> here we go. dip. turn right. >> reporter: but creating a mental map of his 5-mile route. >> as the road sweeps to the right, we need to take the first right-hand turn. >> reporter: he knows these roads so well he could practically drive them. in fact, he was giving me driving directions.

>> so turn right. >> reporter: you realize i'm really depending on you. >> i know where we are, i know where we are. >> reporter: he was flawless. me, not so much. >> so, you're about to sail by it. yep, you sailed by it. >> reporter: i just missed the turn. >> go on the round -- >> reporter: it's all pretty impressive. and simon was getting noticed. when the designers of run keeper learned how simon adapted his map to help him, he was featured in an ad campaign. in 2016 he teamed up with ibm to develop a guidance system named after his guide dog. it was a prototype that gave him audio cues that kept him on course. the growing test was a 155 mile marathon through the namibian desert, no less. he made it almost halfway totally unassisted. >> the system worked, you know.

there is a part of me running through the desert alone. it's just like this was a dream a few years ago. now i'm actually doing it. >> reporter: and then what happened? >> on the second day i managed to run into the only flag pole in the desert. >> reporter: a flag pole? >> i took a big blow from the flag pole to the face. >> reporter: the worst was when he ran head long into the twisted remnants of a burned out car while training on his route near his house. >> turned out it was blood pouring down my arm and that's when i pulled out the phone to call my wife. you have to come fin>>t wasd qu know what we were going to fi n. erdth little more nftch a careful. >> reporter: the woman he ill-fated hike isn't all that keen on her pushing the envelope. they have two sons tolkt, grayson and franklin.

she knows although it's dangerous, there is a bigger picture. >> he wants to change the world for blind people. he wants to prove that they can do whatever they set their mind to. >> reporter: pretty lofty goal. >> yeah. i think he can actually do it. >> reporter: we were there when he opened a new piece of technology to test called ira. >> i feel a little space age. >> reporter: it's sort of a google glass on steroids. a new service visually impaired people can subscribe to in the u.s. >> thank you for calling ira. how can i help you? >> reporter: it beams back to a sighted agent. >> you'll go slightly to the right towards 1:00 to avoid it. >> reporter: simon was the first in the u.k. to try it. he took it to a local market where the agent at the other end helped him browse the store shelves. >> i'm after the one with the green tub, so what color top -- >> that's got a green top.

>> perfect the reason i wanted this was to demonstrate it to as many blind people. it can remove those difficult points in your life. this could be a true independence piece of technology. do you want to see the new glasses i got? >> yes! >> reporter: simon thinks ira just might be the breakthrough that could make his dream of running solo come true. he's studying for his moose terz in computer science and he hopes to continue perfecting more technology for the blind. >> the goal is this piece of technology exists so people can do all these things and more safely. they shouldn't have to take the risk that i took. >> reporter: he's no hero, he says, nor does he consider himself an inspiration. he's a test pilot of sorts for those who are blind or visually impaired who, like him, hope technology may one day brighten their world.

>> now, that is amazing. lee cowan when you humble yourself under the mighty hand of god, in due time he will exalt hi, i'm joel osteen. i'm excited about being with you every week. i hope you'll tune in. you'll be inspired, you'll be encouraged. i'm looking forward to seeing you right here. you are fully loaded and completely equipped for the race that's been designed for you.

we all have that one facebook friend who insists on correcting the grammar in our post. what if you bumped into one of those people on the street? steve hartman did just that. >> reporter: imagine you're out walking, shopping or doing some other errand when -- >> do you have a grammar question? >> reporter: a woman on the street prepositions you. >> over is a preposition, under is a preposition. >> reporter: what would you think? >> people must be impressed when you know this kind of stuff. >> reporter: you might think whom is this crazy lady? >> do you have any grammar questions? >> reporter: who sees grammar as such an imperative she sets up a table just to talk about it? >> because i love grammar so much. >> reporter: you couldn't think of anything more interesting? right now we're using words. this wouldn't even be happening. we'd be looking at each other. >> reporter: by day ellen runs a

company training people in business communications. but her real passion is linguistics. she has a huge library of grammar and style books from arabic to zulu to share the knowledge and have some fun. last year she began setting up her grammar table around new york city where she lives, and it went so well she is now taking the table to the collective noun that is america. we caught up with her in new hope, pennsylvania, where ellen spent the day reminding people how to diagram sentences. >> i bet you remember this. >> reporter: explaining when to use who and whom. >> and do you know why? >> reporter: and counseling people on their comma addictions. >> are you a comma user? >> yes, i probably over use them. >> we have an urge to leave them out sometimes. >> reporter: she answered something i've always wondered about. does the period have to go inside the quotation mark or can it go outside in certain circumstances? how about the story steve did on the gra w

interesting. where does the period go there? because i'm using interesting in an ironic way. >> yes, i understand that completely. it always goes inside. so, in this sentence - >> reporter: ellen says her favorite part is settling grammar disputes between husbands and wives. >> i resolved that and i feel good about that. >> reporter: she said it's been very enlightening. >> in my experience, usually if a couple comes up, usually the woman is right. i mean, in my -- >> reporter: i'm grammarless right now. she hung me out like a dangling modifier. you can't help but love her passion and a lot of peopl do appreciate her mission. this guy at at redht had know right then and there, do you always capitalize after a colon? >> if it's only a piece of a sentence dench knitdefinitely n cap. >> reporter: that made her day. one more comfort in her growing army of grammar defenders. >> people love to be corrected
