RIO DE JANEIRO -- Olympic sailors competing in the Rio de Janeiro may navigate through fetid waters and possibly bump into floating trash. But if they are lucky enough, they might also sail past a few dozen dolphins that live in Guanabara Bay.Despite the untreated sewage and toxic industrial pollution that flows into bay waters, 34 Guiana dolphins live, breed and feed in the bay.Still, the dolphin population here is in rapid decline, down from 400 in the 1980s, according to marine biologists who track them.Scientists warn that the grey mammals with bottle-neck shaped noses that adorn Rio de Janeiros city logo could disappear from Guanabara Bay in a matter of years.This is our backyard, said Rafael Ramos, a researcher with the Maqua institute at Rio de Janeiro state university that has monitored the dolphin population in Guanabara Bay since 1992. It must be treated as a gem.While the rivers that flow into the bay are dark and thick with raw sewage and toxic chemicals, at the bottom end of the bay, the Guapimirim conservation area serves as a refuge for these dolphins.Yet researchers say the mammals transit in other parts of the bay as well, swimming around countless cargo ships, oil tankers, fishing boats and cruise liners.Unlike other species, the Guiana dolphins do not migrate or flee their habitat to look for a new home when threatened by human growth and development.Consequently ,many dolphins die early and frequently. Every year, several are found floating lifelessly in the bay and their corpses are taken in by Maqua researchers for study.While causes of death can vary, they all originate in the degradation and human exploration of the bay says Haydee Cunha, a biology professor at Rios state university who studies the genetics of the Guiana dolphins at the Maqua Institute.Unfortunately, if we dont do anything to change this scenario, in a few years, perhaps in a decade, the Guiana dolphins will disappear from Guanabara Bay, said Cunha.

PITTSBURGH -- Replacing Cam Heyward the football player may be the easy part for the Pittsburgh Steelers. Finding someone to do all the things their injured defensive end -- out for the season with a torn pectoral muscle -- does on the field that dont show up on tape will be considerably more difficult.It definitely hurts us, linebacker Ryan Shazier said. It punches you in the heart because hes the heart of our defense.One who does more than simply shrug off blocks and wrap up running backs. Heyward is one of Pittsburghs four captains for reasons that go far beyond simple talent. He makes the line calls, offers in-game pointers and serves as the emotional fulcrum for the guys around him.Now hes gone after an MRI discovered the twinge he felt in last weeks loss to Dallas was actually his pectoral muscle shredding itself, leaving behind a defense thats failed to limit big plays during a four-game losing streak thats sent the Steelers (4-5) tumbling into a midseason crisis. While the winless Cleveland Browns (0-10) offer the promise of a temporary salve on Sunday, Pittsburgh understands it needs to find a way to get better quickly if it truly wants to turn things around.Its hard to lose a guy like your captain and stuff like that, quarterback Ben Roethlisberger said. But other guys have to step up. I mean, its that time of year.If the Steelers want to get it together, they dont really have much of a choice.Weve just all got to get better as a group, rookie nose tackle Javon Hargrave said. Thats our leader. Hes the oldest on the D-line. He knows more than us. Weve just got to grow up.Quickly. The defensive front faltered when a bum left hamstring forced Heyward out of the lineup for the first time in his six-year career last month. He could only watch in frustration as Miamis Jay Ajayi became the first player in 16 years to go over 200 yards rushing against Pittsburgh in a Week 6 loss and New Englands Garrett Blount bulled his way for 127 yards and a pair of touchdowns seven days later.Teams been running on us a lot lately, nose tackle Daniel McCullers said. Thats not Steeler defense.At least not the way Pittsburgh used to play it. Not so much anymore. The proof came in the final 2 minutes last wweek against Dallas, when Ezekiel Elliott sprinted to the end zone twice to rally the Cowboys to a victory that sent the Steelers to their fourth straight loss.dddddddddddd And that was with Heyward in the huddle. Now theyve got to clean up the mistakes without him.Sometimes we get in the right spots and were not executing, Shazier said. Sometimes were in the right spots, getting moved out of the way and sometimes were not doing the right thing.Heywards absence puts more pressure on Stephon Tuitt, who defensive coordinator Keith Butler will move up and down the line in search of mismatches. Thats fine by Tuitt, who has shown flashes of dominance at times but will now be asked to do it on a more consistent basis. Hes developed a close friendship with Heyward during his three years in the league, in part because he knew at some point this moment would arrive.Its gonna be tough because we have a partnership, we have a chemistry, Tuitt said.One Tuitt will try to develop with Hargrave, McCullers and Ricardo Matthews. Tuitt is more reserved by nature and joked earlier in the year he doesnt pay attention to the game plan and instead simply does what Heyward tells him to do. Now Tuitt will find himself doing the yelling.For me to get this role now, its not under the circumstances I want them to be under but I almost get the veteran role back and teach my defensive linemen and lead by example.Heyward will still be around on the sideline and in meeting rooms. But not having his familiar No. 97 in the huddle will take some getting used to for a group thats grown accustomed to his steadying influence.Hes like a brother to us outside of football, McCullers said. We always spend time with each other, hang out. Its big (to lose him). Weve got to play hard for him.Game notes TE Ladarius Green (knee), WR Sammie Coates (finger), S Jordan Dangerfield (groin) and TE Xavier Grimble (quadriceps) were limited on Wednesday. ...
