the vastness of the Great Plains. 10 00:00:55,863 --> 00:00:58,462 [thunder rumbling] 11 00:01:15,617 --> 00:01:18,782 To where the forests and swamps of the Deep South 12 00:01:18,917 --> 00:01:22,754 give way to the Blackland Prairies and Post Oak Savannas. 13 00:01:22,889 --> 00:01:25,192 [birds chirping] 14 00:01:31,326 --> 00:01:34,527 From the spring-fed rivers that bless the Hill Country... 15 00:01:35,230 --> 00:01:38,502 to the tropical brush of the Rio Grande Valley. 16 00:01:40,301 --> 00:01:44,173 Texas gives life to animals found nowhere else... 17 00:01:45,109 --> 00:01:48,380 and attracts migrations from across the hemisphere. 18 00:01:52,581 --> 00:01:54,786 [wings cutting the air] 19 00:01:54,922 --> 00:01:57,323 [birds squawking] 20 00:02:20,208 --> 00:02:23,514 More headwater springs to the Gulf of Mexico. 21 00:02:24,415 --> 00:02:27,188 It is a land sculpted by water. 22 00:02:27,690 --> 00:02:29,820 [rattling] 23 00:02:29,956 --> 00:02:33,219

26 00:03:02,053 --> 00:03:06,227 This film celebrates the natural wonders of Texas. 27 00:03:08,058 --> 00:03:11,259 It is a story about tragedies in our past... 28 00:03:11,862 --> 00:03:14,396 of recoveries against all odds... 29 00:03:15,066 --> 00:03:18,170 and is a call to action to conserve the wildlife 30 00:03:18,305 --> 00:03:21,341 and wild places in our home. 31 00:03:25,546 --> 00:03:29,679 This is a story for all who love Texas. 32 00:03:36,792 --> 00:03:38,886 [wind whistling] 33 00:03:50,838 --> 00:03:54,168 The history of our relationship with wildlife in Texas... 34 00:03:55,305 --> 00:03:58,642 is best told on the High Plains of the Panhandle. 35 00:04:20,631 --> 00:04:26,307 For millennia, herds of Bison roamed across Texas by the millions. 36 00:04:28,809 --> 00:04:31,742 Their grazing patterns shaped our landscapes, 37 00:04:32,278 --> 00:04:36,075 and their meat and hides nourished the people who lived here. 38 00:04:46,357 --> 00:04:47,990 [bison grunts] 39 00:04:48,125 --> 00:04:52,058 They survived ice ages and mass extinctions. 40 00:04:55,468 --> 00:04:57,602 But their ability to thrive... 41 00:04:58,672 --> 00:05:02,040 was no match for westward expansion. 42 00:05:02,176 --> 00:05:04,477 [melancholic music] 43 00:05:12,716 --> 00:05:14,513 Only three lifetimes ago, 44 00:05:14,649 --> 00:05:18,788 30 million bison roamed the Great Plains of North America. 45 00:05:21,262 --> 00:05:23,562 So many, they seemed limitless. 46 00:05:27,866 --> 00:05:30,136 They attracted market hunters West 47 00:05:30,271 --> 00:05:33,770 where an experienced buffalo hunter could often kill hundreds a day. 48 00:05:36,370 --> 00:05:39,376 Their hides and tongues were sold to markets 49 00:05:39,511 --> 00:05:41,547 along the East Coast and Europe. 50 00:05:43,119 --> 00:05:44,980 The meat was left to rot 51 00:05:45,116 --> 00:05:48,521 or was laced with poison to kill off predators. 52 00:05:53,024 --> 00:05:55,559 Efforts to slow the killing were ignored... 53 00:05:56,762 --> 00:06:00,865 for the great Slaughter destroyed the food source of Native Americans... 54 00:06:01,768 --> 00:06:04,064 forcing many under reservations. 55 00:06:07,876 --> 00:06:10,939 Commercial market hunting wasn't limited to bison. 56 00:06:12,142 --> 00:06:14,109 Most abundant bird in North America, 57 00:06:14,244 --> 00:06:17,550 passenger pigeon, was hunted to extinction. 58 00:06:19,115 --> 00:06:22,822 Wild sheep, pronghorn, deer, and elk 59 00:06:22,957 --> 00:06:25,855 were killed from all but the most remote locations. 60 00:06:27,929 --> 00:06:31,630 Waterfowl and shorebirds were shot by the millions. 61 00:06:33,363 --> 00:06:37,999 Jaguars, grizzlies, and wolves were killed from Texas. 62 00:06:42,573 --> 00:06:44,370 By the late 1800s, 63 00:06:45,039 --> 00:06:47,712 our wildlife was decimated. 64 00:07:05,230 --> 00:07:09,331 Legend has it that Texas rancher Molly Goodnight heard 65 00:07:09,466 --> 00:07:13,672 the last bison calves crying out for their slaughtered mothers. 66 00:07:15,838 --> 00:07:17,973 Of the five million in Texas... 67 00:07:18,676 --> 00:07:20,943 only five remained. 68 00:07:23,812 --> 00:07:26,113 [gentle lively music] 69 00:07:27,414 --> 00:07:31,151 She saved them and their numbers grew. 70 00:07:34,896 --> 00:07:38,424 They lived in Palo Duro Canyon until the 1990s 71 00:07:38,560 --> 00:07:41,327 when they were given to Texas Parks and Wildlife 72 00:07:41,462 --> 00:07:43,999 and moved to Caprock Canyon State Park. 73 00:07:48,872 --> 00:07:51,710 These are their descendants. 74 00:07:53,213 --> 00:07:57,617 The survivors of the great Southern Plains bison herd. 75 00:07:59,285 --> 00:08:00,587 [bison grunting] 76 00:08:05,427 --> 00:08:08,155 The herd is over 300 strong. 77 00:08:08,891 --> 00:08:11,730 And this is the future. 78 00:08:16,599 --> 00:08:18,902 [birds chirping] 79 00:08:26,243 --> 00:08:29,209 Learning to be a bison is hard work. 80 00:08:30,852 --> 00:08:34,148 Especially when you have to walk on day one. 81 00:08:40,391 --> 00:08:43,429 These wobbly legs will need to be strengthened. 82 00:08:43,965 --> 00:08:46,992 And it's a good thing mom's here to help. 83 00:08:47,127 --> 00:08:49,229 [inspirational lively music] 84 00:08:51,466 --> 00:08:54,036 They have an entire prairie to explore. 85 00:08:54,904 --> 00:08:56,643 And neighbors to meet. 86 00:09:10,687 --> 00:09:13,819 Like all communities, there's always that one neighbor... 87 00:09:14,822 --> 00:09:18,192 coming out of their hole with their feathers all ruffled. 88 00:09:28,670 --> 00:09:31,577 There's a diversity of creatures on these plains. 89 00:09:32,080 --> 00:09:34,274 And this calf needs to learn how to run in order 90 00:09:34,409 --> 00:09:36,375 to keep up with the herd one day. 91 00:09:38,014 --> 00:09:39,884 Which will take some practice. 92 00:09:54,863 --> 00:09:57,165 [owl chirping] 93 00:10:07,876 --> 00:10:12,246 Maybe a little teamwork will help improve the coordination. 94 00:10:24,431 --> 00:10:25,864 [owl chirping] 95 00:10:28,431 --> 00:10:30,868 These calves may only be a few weeks old... 96 00:10:31,571 --> 00:10:35,407 but the blood of Texas survivors flows through their veins. 97 00:10:35,542 --> 00:10:37,843 [inspirational music] 98 00:10:39,844 --> 00:10:42,881 They were born to run. 99 00:11:19,749 --> 00:11:23,857 These bison won't roam the same prairies as their ancestors. 100 00:11:24,593 --> 00:11:27,255 But there is room to expand. 101 00:11:54,949 --> 00:11:56,383 [bison grunting] 102 00:11:57,926 --> 00:11:59,855 There are public lands across Texas 103 00:11:59,990 --> 00:12:02,221 that can be restored with bison. 104 00:12:02,791 --> 00:12:05,964 Many ranches have already answered their call. 105 00:12:09,467 --> 00:12:12,531 Bison herds are expanding across the state. 106 00:12:13,608 --> 00:12:15,072 And they aren't alone. 107 00:12:21,216 --> 00:12:24,142 Following the Great Slaughter of the late 1800s... 108 00:12:24,845 --> 00:12:28,514 a series of laws were passed to recover our wildlife. 109 00:12:30,554 --> 00:12:33,223 Commercial market hunting was put to an end 110 00:12:33,358 --> 00:12:35,858 and conservation-minded sportsmen advocated 111 00:12:35,993 --> 00:12:37,996 for hunting limits and seasons. 112 00:12:40,028 --> 00:12:44,833 The creation of forest, parks, and refuges provided habitat. 113 00:12:45,736 --> 00:12:49,403 And international agreements protected migratory birds. 114 00:12:52,179 --> 00:12:54,547 The combined efforts to restore some animals 115 00:12:54,682 --> 00:12:56,883 have been remarkably successful. 116 00:12:58,020 --> 00:13:00,684 And many species that were killed out of an area 117 00:13:00,820 --> 00:13:02,350 have been reintroduced. 118 00:13:02,853 --> 00:13:05,453 [distant calling] 119 00:13:05,588 --> 00:13:10,028 In Texas today, elk bugle from mountaintops. 120 00:13:11,128 --> 00:13:13,225 Pronghorn grace the prairie. 121 00:13:13,894 --> 00:13:17,838 And desert bighorn have returned to their mountain homes. 122 00:13:21,771 --> 00:13:25,575 These recoveries are largely due to people who have dedicated... 123 00:13:26,678 --> 00:13:31,478 and some who have given their lives to restore our wildlife. 124 00:13:36,391 --> 00:13:38,485 [birds chirping] 125 00:13:40,921 --> 00:13:45,096 But there is one specie that reign supreme on recovery. 126 00:13:56,304 --> 00:13:58,208 The white-tailed deer. 127 00:14:03,884 --> 00:14:05,549 At the end of each winter, 128 00:14:05,684 --> 00:14:09,186 the buck shed their antlers and begin to grow a new set. 129 00:14:12,991 --> 00:14:14,554 During the velvet stage, 130 00:14:14,689 --> 00:14:17,161 antlers can grow a quarter inch a day 131 00:14:17,297 --> 00:14:19,431 and under good rangeland conditions, 132 00:14:19,567 --> 00:14:23,167 the bucks put extra resources into their antlers' growth. 133 00:14:26,007 --> 00:14:29,338 [suspenseful inspirational music] 134 00:14:32,781 --> 00:14:34,776 As summer fades into fall, 135 00:14:34,911 --> 00:14:39,150 their testosterone increases and they rub the velvet off. 136 00:14:41,350 --> 00:14:43,550 Revealing a fresh new set... 137 00:14:44,889 --> 00:14:46,190 of weapons. 138 00:14:55,998 --> 00:15:00,900 The rut, the breeding season, lasts for only a month... 139 00:15:01,869 --> 00:15:05,044 which they have spent all year preparing for. 140 00:15:13,147 --> 00:15:15,450 [clattering] 141 00:15:37,542 --> 00:15:39,573 Most fights are settled within seconds... 142 00:15:41,010 --> 00:15:43,709 for the risk of injury is high and the larger buck 143 00:15:43,844 --> 00:15:46,613 typically exerts his dominance quickly. 144 00:15:50,055 --> 00:15:52,355 [footsteps approaching] 145 00:15:56,297 --> 00:15:58,592 But when opponents are evenly matched... 146 00:15:59,931 --> 00:16:01,098 a showdown... 147 00:16:01,634 --> 00:16:05,533 for breeding rights and territory is inevitable. 148 00:16:42,310 --> 00:16:45,441 Each doe is in heat for only 24 hours. 149 00:16:46,845 --> 00:16:50,778 The buck's bloodlines and territories are at stake. 150 00:16:51,214 --> 00:16:53,217 [clattering continues] 151 00:16:53,353 --> 00:16:55,649 [suspenseful inspirational music continues] 152 00:17:54,208 --> 00:17:56,512 [panting] 153 00:18:01,954 --> 00:18:03,752 [insects chirping] 154 00:18:03,887 --> 00:18:07,523 These incredible dramas should not be taken for granted. 155 00:18:11,264 --> 00:18:16,335 A century ago, white-tailed deer had been killed from most of the state 156 00:18:16,470 --> 00:18:18,897 and only survived in isolated pockets. 157 00:18:24,741 --> 00:18:27,740 Today, largely due to regulations 158 00:18:27,876 --> 00:18:30,048 and conservation-minded sportsmen, 159 00:18:30,183 --> 00:18:32,284 there are over five million. 160 00:18:39,252 --> 00:18:42,558 Other species have not shared the same fate. 161 00:18:49,869 --> 00:18:54,200 In a very few special parts of the South Texas brush country... 162 00:18:54,336 --> 00:18:57,343 [gentle music] 163 00:18:57,478 --> 00:19:00,543 lives a creature once thought to be lost. 164 00:19:10,658 --> 00:19:15,320 An animal so rare, it has become nearly mythical. 165 00:19:15,456 --> 00:19:17,758 [owl hooting] 166 00:19:39,150 --> 00:19:40,451 An ocelot. 167 00:19:53,733 --> 00:19:57,666 Fewer than 80 are known to exist in the entire country. 168 00:20:07,175 --> 00:20:10,048 Ocelots were once found across much of Texas 169 00:20:10,183 --> 00:20:12,114 and into Louisiana and Arkansas. 170 00:20:12,250 --> 00:20:13,913 [melancholic music] 171 00:20:14,049 --> 00:20:16,388 Much of their habitat has been lost. 172 00:20:16,524 --> 00:20:18,216 Then they were historically trapped, 173 00:20:18,351 --> 00:20:22,592 hunted and poisoned by government predator programs. 174 00:20:26,260 --> 00:20:29,766 Today they exist in only two small populations, 175 00:20:29,902 --> 00:20:32,965 where they are genetically isolated and inbred. 176 00:20:34,637 --> 00:20:37,037 A catastrophic fire, hurricane 177 00:20:37,172 --> 00:20:40,139 or disease could wipe them from the country. 178 00:20:41,576 --> 00:20:45,381 Much is unknown, for many landowners have not allowed research 179 00:20:45,517 --> 00:20:49,653 on their property because they are concerned that the Endangered Species Act 180 00:20:49,788 --> 00:20:52,457 would impact their ranching operations. 181 00:20:54,591 --> 00:20:57,660 Texas is 95% privately owned, 182 00:20:57,795 --> 00:20:59,598 and recovering endangered species 183 00:20:59,734 --> 00:21:02,328 is very difficult without landowners support. 184 00:21:02,464 --> 00:21:04,465 [cows mooing] 185

remove more water than rainfall can refill, 352 00:42:30,319 --> 00:42:34,120 the water table falls, and the springs go dry. 353 00:42:37,723 --> 00:42:41,091 During the last century, one half of the

human and can live just as long. 593 01:21:23,582 --> 01:21:25,655 She has left the safety of the river 594 01:21:25,790 --> 01:21:27,924 and is following the floods. 595 01:21:30,256 --> 01:21:34,192 These wetlands will provide the best opportunity for her offspring. 596 01:21:34,627 --> 01:21:37,626 In a place free from other river predators. 597 01:21:43,503 --> 01:21:45,869 She releases pheromones as she travels 598 01:21:46,305 --> 01:21:48,175 for her suitors to follow. 599 01:21:50,913 --> 01:21:53,213 And they have proven attractive. 600 01:22:00,784 --> 01:22:02,586 With scales like a suit of armor, 601 01:22:02,721 --> 01:22:05,489 she leads him further into the shallows. 602 01:22:10,496 --> 01:22:14,797 She has likely waited five to ten years for the right conditions to spawn. 603 01:22:15,767 --> 01:22:19,170 And she will release over 100,000 eggs 604 01:22:19,539 --> 01:22:22,242 which the males fight to fertilize. 605 01:22:44,135 --> 01:22:45,928 Her eggs will hatch in only two days 606 01:22:46,063 --> 01:22:49,001 and the baby gar will be swept back into the river 607 01:22:49,137 --> 01:22:51,172 as the floodwaters recede. 608 01:22:54,311 --> 01:22:56,608 It is a life strategy so successful, 609 01:22:56,743 --> 01:23:01,512 that alligator gar have lived here for 70 million years. 610 01:23:03,246 --> 01:23:05,582 [birds chirping] 611 01:23:09,427 --> 01:23:13,561 Our waterways are home to nearly 200 native Texas fish. 612 01:23:14,297 --> 01:23:17,066 Over a dozen are found nowhere else. 613 01:23:18,896 --> 01:23:21,803 They have evolved for natural water flow, 614 01:23:21,939 --> 01:23:23,164 which has been disrupted. 615 01:23:23,299 --> 01:23:25,602 [soft music] 616 01:23:27,643 --> 01:23:30,978 We have lost one half of our wetlands in Texas, 617 01:23:31,447 --> 01:23:34,182 which act as nature's flood control. 618 01:23:35,780 --> 01:23:38,153 They are often replaced by concrete, 619 01:23:38,288 --> 01:23:40,584 which increases the flooding downstream. 620 01:23:46,897 --> 01:23:48,262 To mitigate flooding, 621 01:23:48,397 --> 01:23:51,496 over 7000 dams have been constructed... 622 01:23:52,464 --> 01:23:54,028 which also irrigate crops, 623 01:23:54,163 --> 01:23:57,535 generate electricity, and supply our cities. 624 01:23:59,070 --> 01:24:02,672 The reservoirs dams create are exposed to the sun. 625 01:24:04,311 --> 01:24:06,478 During the drought of 2011, 626 01:24:06,613 --> 01:24:08,580 more water was lost to evaporation 627 01:24:08,715 --> 01:24:11,852 than was used by all of our cities combined. 628 01:24:11,987 --> 01:24:14,288 [intriguing gentle music] 629 01:24:22,861 --> 01:24:25,665 The impact to our watersheds is so great 630 01:24:25,801 --> 01:24:29,367 that hundreds of miles of our rivers no longer flow. 631 01:24:30,036 --> 01:24:34,275 And one half of our native fish species are imperiled. 632 01:24:41,282 --> 01:24:42,945 We depend on the same water. 633 01:24:43,614 --> 01:24:45,484 And we are making progress. 634 01:24:48,691 --> 01:24:51,387 In the last 30 years, the average water use per Texan 635 01:24:51,523 --> 01:24:53,327 has been cut by a quarter. 636 01:24:55,526 --> 01:24:57,466 Landscaping with native plants, 637 01:24:57,601 --> 01:25:01,503 improving irrigation technology, storing water underground, 638 01:25:01,638 --> 01:25:05,372 and increasing efficiency has potential to save much more. 639 01:25:08,371 --> 01:25:11,411 Scientists are finding ways to release water from dams 640 01:25:11,547 --> 01:25:13,715 that allow our native fish to spawn. 641 01:25:14,618 --> 01:25:18,286 And some dams that are no longer useful can be taken down. 642 01:25:22,224 --> 01:25:24,493 Conserving water is crucial... 643 01:25:25,629 --> 01:25:28,489 for flowing rivers are the arteries of Texas... 644 01:25:29,259 --> 01:25:32,800 and the lifeblood of our bays and estuaries. 645 01:25:32,935 --> 01:25:35,237 [birds calling] 646 01:25:58,522 --> 01:26:00,625 [dolphin whistling] 647 01:26:02,566 --> 01:26:07,236 Our coastline is unique due to a distinctive geography. 648 01:26:09,673 --> 01:26:13,374 Texas is protected by barrier islands and peninsulas. 649 01:26:16,405 --> 01:26:19,140 When salt water from the Gulf passes through them, 650 01:26:19,276 --> 01:26:22,977 it combines with the fresh water and nutrients from our rivers... 651 01:26:25,786 --> 01:26:28,357 creating an underwater prairie of grass 652 01:26:28,626 --> 01:26:31,458 that attracts life from across the hemisphere. 653 01:26:34,427 --> 01:26:36,632 [wings cutting the air] 654 01:26:36,767 --> 01:26:38,861 [birds chirping] 655 01:26:54,377 --> 01:26:58,353 The migrations that come through our coastline are so vast 656 01:26:58,488 --> 01:27:00,319 that the second highest passage rate 657 01:27:00,454 --> 01:27:02,456 of migratory birds on Earth, 658 01:27:02,591 --> 01:27:05,294 was recorded right here in Texas. 659 01:27:08,095 --> 01:27:09,991 [ducks quacking] 660 01:27:16,003 --> 01:27:21,305 These coastal marshes are also home to a master of ambush. 661 01:27:21,440 --> 01:27:23,708 [light suspenseful music] 662 01:27:34,056 --> 01:27:35,456 Alligators. 663 01:28:22,535 --> 01:28:27,376 Islands along the coast provide crucial habitat for colonial waterbirds 664 01:28:27,511 --> 01:28:29,972 to build nests and raise their chicks. 665 01:28:51,762 --> 01:28:53,228 As the youngsters grow, 666 01:28:53,363 --> 01:28:55,702 they begin to explore their surroundings... 667 01:28:56,939 --> 01:29:01,003 creating an opportunity for those with patience. 668 01:29:47,817 --> 01:29:49,355 Below the surface, 669 01:29:49,824 --> 01:29:52,094 the mixture of fresh and salt water 670 01:29:52,229 --> 01:29:54,095 creates a nursery for the Gulf. 671 01:29:54,230 --> 01:29:56,531 [gentle upbeat music] 672 01:30:00,304 --> 01:30:02,471 Like many coastal species, 673 01:30:02,606 --> 01:30:04,870 redfish are born as eggs in the ocean 674 01:30:05,005 --> 01:30:08,103 and swept into the bays by incoming tides. 675 01:30:12,143 --> 01:30:14,011 As juveniles, they hunt these shallows 676 01:30:14,147 --> 01:30:16,947 until they grow large enough for life at sea. 677 01:30:23,924 --> 01:30:26,055 In September of their third year, 678 01:30:26,424 --> 01:30:29,757 a biological urge triggers them to congregate, 679 01:30:30,059 --> 01:30:33,062 and to begin their migration. 680 01:31:03,426 --> 01:31:06,133 Driven by instinct and following the tides, 681 01:31:06,268 --> 01:31:09,934 they are swimming to the ocean to live out their adult lives. 682 01:31:11,908 --> 01:31:15,269 With them, flow nutrients from across Texas. 683 01:31:18,041 --> 01:31:20,012 Transported by our rivers, 684 01:31:20,148 --> 01:31:24,212 the gift of fresh water reaches the Gulf of Mexico. 685 01:31:31,527 --> 01:31:36,191 For the first few leagues offshore, sediment clouds the water. 686 01:31:37,863 --> 01:31:39,694 But with distance and depth, 687 01:31:39,963 --> 01:31:42,598 the Gulf reveals her true color. 688 01:31:42,733 --> 01:31:45,035 [intriguing music] 689 01:31:50,979 --> 01:31:54,141 This deep blue world seems far from our own, 690 01:31:54,610 --> 01:31:57,451 yet nutrients from our bays and estuaries 691 01:31:57,586 --> 01:31:59,287 fuel much of the plankton... 692 01:32:00,090 --> 01:32:03,691 which are the building blocks of life in the Gulf. 693 01:32:04,788 --> 01:32:07,090 [gentle music] 694 01:32:09,026 --> 01:32:11,128 In a few very special places, 695 01:32:11,263 --> 01:32:13,395 salt domes have risen from the seafloor 696 01:32:13,531 --> 01:32:16,497 and combined with tropical currents from the south. 697 01:32:17,700 --> 01:32:22,270 Here, this plankton fuels the Texas Caribbean... 698 01:32:33,484 --> 01:32:37,890 the Flower Garden Banks National Marine Sanctuary. 699 01:33:02,249 --> 01:33:06,215 Each of these corals is composed of millions of polyps. 700 01:33:08,285 --> 01:33:10,956 Each polyp feeds on the plankton. 701 01:33:14,058 --> 01:33:16,291 It is an oasis of life... 702 01:33:16,961 --> 01:33:19,096 in a desert of blue. 703 01:33:27,406 --> 01:33:30,877 We are still unraveling the mysteries that abound here. 704 01:33:33,176 --> 01:33:34,980 What we've learned thus far... 705 01:33:35,716 --> 01:33:38,313 is nearly beyond imagination. 706 01:33:45,925 --> 01:33:47,661 Shortly after the sunset, 707 01:33:48,097 --> 01:33:50,965 during the week after the full moon in August, 708 01:33:51,101 --> 01:33:55,000 one of nature's most remarkable events unfolds. 709 01:34:06,547 --> 01:34:08,849 [gentle music] 710 01:34:15,919 --> 01:34:17,220 The corals... 711 01:34:17,954 --> 01:34:19,189 are spawning. 712 01:34:27,135 --> 01:34:29,164 We do not know how they communicate, 713 01:34:29,499 --> 01:34:32,499 but in unison, millions of coral polyps 714 01:34:32,634 --> 01:34:36,041 release and fertilize their offspring. 715 01:35:03,640 --> 01:35:08,943 This seemingly alien world exists far from our daily consciousness. 716 01:35:10,613 --> 01:35:14,844 Yet it is connected in ways that we are just beginning to understand. 717 01:35:14,979 --> 01:35:17,280 [light suspenseful music] 718 01:35:32,127 --> 01:35:34,099 [water lapping] 719 01:35:36,834 --> 01:35:38,499 [ducks quacking] 720

Urban areas are expanding, 727 01:37:05,421 --> 01:37:07,093 landscapes are subdividing 728 01:37:07,228 --> 01:37:09,693 as ranches split with the generations. 729 01:37:10,729 --> 01:37:14,034 And energy demand is consuming millions of acres. 730 01:37:23,544 --> 01:37:26,277 Climate change will bring more severe droughts, 731 01:37:26,412 --> 01:37:29,445 weather variability, and hurricanes. 732 01:37:35,422 --> 01:37:37,619 Some of our rivers are entirely consumed 733 01:37:37,755 --> 01:37:41,127 and no longer flow to the sea during drought years. 734 01:37:47,402 --> 01:37:50,837 We've lost a quarter of our birds in the last 50 years. 735 01:37:51,473 --> 01:37:55,036 And there are 69 species that are state endangered 736 01:37:55,438 --> 01:37:57,671 and 148 that are threatened. 737 01:38:08,550 --> 01:38:11,421 Their future is our choice. 738 01:38:12,928 --> 01:38:14,721 And there is reason for hope. 739 01:38:15,257 --> 01:38:17,465 [birds singing] 740 01:38:17,601 -->
