u.s. if people try capping the cost of cr people already know the feeling of life without power and heat. debora patta has that story. >> reporter: winter is coming. an ominous icy threat.

you still don't have gas. you have no heating, and you can't cook. what are you going to do? "i don't know," she says, gulping back sobs. it's a fear shared by europe where an energy crisis could lead to rolling blackouts, shuttered factories and a deep recession. russia has choked off supplies from the nord stream 1 pipeline. cynically, the russians is a say they had no choice. aimed at dividing western allies and their support of them against russia's invasion. gas is now waiting. >> reporter: i hope leaders are wise enough to make the right decisions, she says, because we are all hostages of this war.

she empathizes with facing rising energy bills, but points out that compared to ukraine, it could be a lot worse. >> deborah pat in earp pin, ukraine. it is still reeling from decades of war. earlier this week a suicide bomber killed three people outside the russian embassy in kabul. and in other parts of the country, there are a few signs that the taliban government can rebuild the nation. imtiaz tyab reports. >> reporter: the streets of the province are bustling again. less than an hour's drive from kabul, this taliban stronghold saw little of the progress and freedoms the capital did during the two decades of america's longest war. trapped in the crossfire were villages like this one, dag bagry, which looks like ancient ruins, but what happened there is a pain felt by those who once called it home. it's hard to imagine 20 years ago at the start of the war,

this was a thriving village, full of families. but it quickly became a front line between the taliban and u.s. forces. the village was destroyed and everyone left. except for marshal, the only remaining resident. the fighting here must have been so intense for such devastation. >> translator: yes, the fighting was very intense here, he says. bullets hit every house. u.s. tanks would stop on the main road and shoot at our houses. in the bitter battles between the taliban and u.s. forces, ordinary families were all too often caught in the fighting, or accused of supporting the taliban. the harsh tactics used by some u.s. forces and their afghan allies in raids across rural afghanistan are well documented. the killings, as well as the lack of accountability drove many people living in these areas to support the taliban. in a village nestled in this valley, he says he was arrested

in a night raid by u.s. forces 12 years ago. he tells us three of his sons were shot dead as they slept. we can't confirm his account, but it's been consistent down the years that american raids were common in this area. what did they ask you? what did they say to you? >> translator: when the americans arrested me that night, they asked where the taliban were, he says. i told them i had no connections with them. i asked if they had any proof that i hadded me method the taliban, and they had no answer. >> reporter: so basically, your sons were killed because of a mistake. they came to the wrong house. "when they couldn't prove it, they started asking me why i didn't support the government more," he says. "i kept asking, how should i cooperate more?" >> reporter: who do you blame for your son's killing? "we blame americans, he says. why did they kill innocent people? by 2015, u.s. forces left wardak

meaning consumers and businesses are being advised to avoid them. besides lobster, this includes all east coast snow crab and several species of flounder and atlantic cod. the designation doesn't actually ban eating or selling the fish, but can lead restaurants and grocery stores to drop them from menus or label them unsustainable. >> if the restaurants put up a sign that says don't eat lobster, people are not going to come in and eat lob centers. that's my concern. >> reporter: the problem isn't the fish. it's the fishing gear. seafood watch and government agencies say vertical lines and ropes are a leading cause of injury and death for the critically endangered north atlantic right whale. its population has shrunk by 30% in just the past decade, and there are now fewer than 340 of them alive. >> no one wants to know that their appetite for seafood is driving a species to extinction. so what seafood watch is doing is putting a flag in the ground

right now and saying there is an important issue. let's pay attention. >> reporter: jennifer kimmerly with seafood watch says if an industry changes its fishing practices, it can find a way off this list. but the new england lobster industry is already being battered by climate change. last year we visited the gulf of maine, which is warming faster than 99% of the earth's oceans. warming water is causing some fish species, including lobster, to migrate north. >> my primary fishery is lobster. >> reporter: we met lobsterman steve train, who has started to also farm kelp, otherwise known as seaweed, buzz the lobster catch is increasingly unpredictable. does this feel like a lifeline? >> right now we're heavily dependent on one resource. so if there is a turn in the fishery, there needs to be something else. >> reporter: especially now that the lobster industry is rated red. red. i'm ben when a cold comes on strong,
