york city. thanks so much for staying with us. turning to the war in ukraine, russian attacks on the black sea city of odesa have severely damaged critical port infrastructure and a historic cathedral. yesterday russian president vladimir putin declared the ukrainian counteroffensive had failed. but on the ground ukrainian soldiers say the battle is only stalled partly due to russian landmines. cbs's charlie d'agata joined ukrainian troops who are clearing the mines. and we do want to warn you some of the images you're about to see are graphic. >> reporter: cbs news has learned that injuries and fatalities from landmines have now surpassed those caused by incoming artillery. and while new equipment like a u.s. bradley fighting vehicle is saving lives, soldiers are at risk the moment they step outside. he lost a leg but survived. on an exercise in zaporizhzhia, the sappers, or mine hunters of the 35th marine brigade, take us through a typical scenario.

defused russian mines they've removed from the battlefield. it's not just the sheer number of mines they're finding but the different types. anti-tank, anti-personnel. one particular mine springs out of the ground to about that height and then sprays shrapnel in every direction. call sign mr. brown shows us an array of trophy mines triggered by trip wires. pressure plates. mines booby-trapped to blow up even while they're being removed. using metal detectors is not only dangerous, it's painstakingly slow. but they're not the only tools at their disposal. among other mine-clearing equipment the u.s. has supplied ukraine with these, mine-clearing line charges, or miclics, that can clear a 100-yard path with one detonation. soldiers say the russians target them as soon as they spot them. call sign odesa lost part of his

foot while clearing mines, yet he's back. "we have a soviet version of the miclic," he said, "but it's heavy, noisy and it breaks a lot. we obviously prefer the american miclic, but we don't have enough. hopefully we'll get more in the future." >> that again was cbs's charlie d'agata reporting. now to a disturbing new report from the centers for disease control on the rise of e-cigarette use. more than 10% of young adults in the u.s. are now vaping, a dramatic increase since the start of the pandemic. cbs's adriana diaz shows us why health officials are worried. >> reporter: 20-year-old alex morin says one of the dangers of vaping is how easy it is to hide. >> you can do it in the same room as them. >> it vaporizes, so you don't see any smoke. >> reporter: it's not just young adults who vape. around 14% of high schoolers do too. according to another recent survey. today's cdc data shows white

non-hispanic americans vape more than latino, asian or black youth. and this week the american heart association said that e cigarettes with nicotine are associated with increases in blood pressure and heartrate, but more research is needed on long-term effects. morin says his health issues started when he became addicted at 16 to e-cigarettes containing nicotine. >> while i did it i felt fine. but in between i would get nauseous. >> reporter: he also started experiencing seizures. >> i thought i was watching my son die. >> the effects of vaping on kids and adolescents is an addiction that could come about from the chronic exposure to nicotine. >> reporter: doctors like dr. panagi scaliasato said vaping may cause a range of outcomes but research is limited. >> we don't know the long-term consequences of electronic cigarettes. >> reporter: the morins say the key to stopping vaping is to do it together. >> we're a team. you know? and he knows we've got his back. >> that again was adriana diaz

>> met him again in june, we reunited. >> reporter: alex brooker was born with congenital limb abnormalities and had one leg amputated as a child. adam hughes was born without a lower right leg. and their non-disabled friend josh whitttacomb is the odd man out. >> i don't see you as adam what's his face. >> thank you. >> i see you as adam where's his leg. >> reporter: the show is peppered with jokes about living with a disability. >> look who's going to get to that disabled bog first. the brakes are off. >> you laugh about disability, which can feel, i mean, really subversive and dangerous. is that the whole point? >> well, i mean, to an able-bodied person it might. but josh got really into it. honestly you should see him. oh, i tell you what. >> reporter: when is it okay to laugh about disabilities? >> it's okay to make jokes about

>> reporter: adeputon was a ground breaker for the presenters of "the last leg." alex brooker told us speaking on television about his disabilities has made him feel more comfortable about himself than ever before. >> it wasn't anything like "the last leg" on telly here when i was a kid. and i'd have loved to have seen some of the conversations happen that we've had on the show because when i was a kid there was no one. >> reporter: adam hules believes seeing and hearing from disabled people enriches all of us. >> it gives you a different perspective on the world and that's what makes a good comedian. >> how does it give you a different perspective? >> i don't know, make you don't take stuff for granted. you don't just assume you're going to have all your arms and your legs. every comedian has something wrong with them. that's why we do comedy. >> reporter: do you think of what you've done with this show as almost revolutionary? >> i think there's still work to be done until i've paid my mortgage. >> reporter: ask a comedian a

a while. until one day when kenty set the pooch at the foot of her porch without the wheelchair. >> and i ran in to go get my cup of coffee, came out and he was right here where he is right now. and i was like, how is this going on? >> how did you figure it out? >> i put him back down there and i grabbed my phone to see what was going on. >> reporter: here's the video she recorded. >> and i was like oh, we're into something totally different. >> you never know where life's going to take you. >> you never know.

co-workers, family members and activists believe they know why he died. you guys think it's because of the heat. garcia tells me co-workers told her lopez garcia felt unwell in the middle of the workday. they put him in the shade and gave him water. initially he said he felt better. but when they came back to check on him, lopez garcia was found lifeless near his lunchbox. a vigil was held for him this week as activists demand change. >> these farm workers are out there from sunrise to sunset, even past hours working five, six, seven days, almost seven days a week. >> reporter: currently just five states mandate heat safety protocols for workers. and while osha does have recommendations, there is no federal heat standard. yet according to a study by the national institutes of health, farm workers are 35 times more likely to die of heat exposure than workers in other industries. construction workers have 13 times the risk. for the first time the miami-dade county commission has advanced legislation that will finally require these workers get some regular relief from this brutal heat.

among the proposed protections, a ten-minute break and water every two hours when the heat index hits 90 degrees. heat safety training for workers and supervisors. a $3,000 fine per violation per day for companies that don't comply. >> it's not enough. water, shade, breaks. we shouldn't have to be passing laws on common sense things. >> reporter: garcia is also a farm worker in homestead. she is also scared to go back to work in the brutal heat. >> no matter how hot it is outside you guys are out there working. >> reporter: "what else would we do," she tells me.
