They wait decades until they can reproduce, returning to the same beaches where they were born to lay their eggs. Females can lay hundreds of eggs in one nesting season, yet few will yield hatchlings that survive their first year of life. Beyond these significant natural challenges, sea turtles face multiple threats caused by humans, such as bycatch in commercial fishing gear, illegal trade, consumption, and climate change.

BYCATCH
Worldwide, hundreds of thousands of sea turtles are accidentally caught in shrimp trawl nets, on longline hooks and in fishing gill nets every year. They become fisheries' bycatch—animals accidentally caught in nets intended for other species.

Sea turtles need to reach the surface to breathe and therefore many drown once caught. Incidental capture by fishing gear is the greatest threat to most sea turtles, especially endangered loggerheads, greens, and leatherbacks. This threat is increasing as fishing activity expands.

OVERHARVESTING AND ILLEGAL TRADE
Sea turtles continue to be harvested unsustainably both for human consumption and trade of their parts. Turtle meat and eggs are a source of food and income for many people around the world. Some also kill turtles for medicine and religious ceremonies. Tens of thousands of sea turtles are lost this way every year, devastating populations of already endangered greens and hawksbills.

Killing of turtles for both domestic and international markets continues as well. International trade in all sea turtle species and their parts is prohibited under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), a global agreement among governments to regulate or ban international trade in species under threat. Still, illegal trafficking persists.

HABITAT LOSS
Sea turtles are dependent on beaches for nesting. Uncontrolled coastal development, vehicle traffic on beaches, and other human activities have directly destroyed or disturbed sea turtle nesting beaches around the world. For example, lights from roads and buildings disorient hatchlings away from the sea, and vehicle traffic on beaches compacts the sand, making it impossible for female turtles to dig nests. Turtle feeding grounds such as coral reefs and seagrass beds are damaged and destroyed by activities onshore, including sedimentation from clearing of land and nutrient run-off from agriculture. Beach restoration projects for protecting seaside buildings have also been found to be harmful, through dredging and sand filling.

CLIMATE CHANGE
All stages of a sea turtle's life are affected by environmental conditions such as temperature—even the sex of offspring. Unusually warm temperatures caused by climate change are disrupting the normal ratios, resulting in fewer male hatchlings.

Warmer sea surface temperatures can also lead to the loss of important foraging grounds for sea turtles, while increasingly severe storms and sea level rise can destroy critical nesting beaches and damage nests.

POLLUTION
Sea turtles can mistake floating plastic materials for jellyfish and can choke on them when they try to eat them. These encounters are often fatal. Lost or discarded fishing gear—called ghost gear—entangles sea turtles and can drown or render a turtle unable to feed or swim. Trash on beaches can trap hatchlings and prevent them from reaching the ocean. Oil spills also poison sea turtles of all ages.]]> 2021-11-08 06:54:03 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874309218 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874365153 2021-11-08 07:27:56 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874365153 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874707185 2021-11-08 11:17:36 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874707185 m9639750 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874972189 Tigers can live in a range of environments, including the Siberian taiga, swamps, grasslands, and rainforests. They can be found anywhere from the Russian Far East to parts of North Korea, China, India, and Southwest Asia to the Indonesian island of Sumatra.

After a century of decline, overall wild tiger numbers are starting to tick upward. Based on the best available information, tiger populations are stable or increasing in India, Nepal, Bhutan, Russia and China. An estimated 3,900 tigers remain in the wild,  much more work is needed to protect this species if we are to secure its future in the wild. In some areas, including much of Southeast Asia, tigers are still in crisis and declining in number.

Have you ever wished to be as powerful as a tiger? There are people all around the world who recognize that tigers are powerful animals. Some people think that if they had a little part of a tiger, they would be powerful, too.

There are poachers, or illegal hunters, who kill tigers and sell their body parts to people who think they will get stronger and more powerful with tiger parts. Poachers only hunt tigers to make money for themselves, which is a big problem for the tigers. For example, a mother tiger might get caught in a poacher's trap. Without the mother tiger, the cubs will not survive, so the poacher ended up killing more than just one tiger in his trap.

Habitat Loss
Another huge problem for tigers everywhere is habitat loss. A habitat is the environment where an animal lives.

Tigers can't just live anywhere. Tigers need a habitat that has forest and grassland, and they need to be far apart from each other. Tigers spend most of their lives alone, so they do not do well when they are too close together. As you can see, tigers need lots of space to hunt and live.

The problem is that people want the same space to live in, too. Tigers live in countries such as India, Russia, China and Malaysia. These countries are growing very quickly, and people need the valuable land that tigers like. When people want to log for timber, or build farms, or make more cities in tiger habitats, the tigers lose their space. Without enough habitat, it's very hard for tigers to find enough food and raise their cubs.]]> 2021-11-08 13:17:38 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874972189 m9385308 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874990555 2021-11-08 13:23:21 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1874990555 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1875383221 Blue Whales ]]> 2021-11-08 15:13:40 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1875383221 m94800351 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1875529802 There are 36 dolphin species, found in every ocean. Most dolphins are marine and live in the ocean or brackish waters along coastlines. There are a few species, however, like the South Asian river dolphin and the Amazon river dolphin, or boto, that live in freshwater streams and rivers.The worldwide population of  dolphins is about 600,000.Dolphins have smooth, rubbery skin and are usually colored in some mixture of black, white, and gray. They have two flippers, or fins, on their sides, as well as a triangular fin on the back. Dolphins generally range in size from 6 feet to over 12 feet and can weigh as much as 600 pounds. Smaller dolphins typically live in rivers and along the coasts, while the larger dolphins range far out to sea.Dolphins are endangered because of human behaviour.The biggest threat to the dolphin population is fishing. Nets from fishing boats are very dangerous to dolphins because they can get accidentally caught up in them and drown. In some countries, dolphins are even illegally hunted as a source of food.Human pollution is another big threat to dolphins. Waste and chemicals poured into the ocean can make dolphins sick and reduce their ability to fight infections and diseases.]]> 2021-11-08 15:55:49 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1875529802 https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1878390573 2021-11-09 14:21:05 UTC https://padlet.com/g26032162/pxof46jwm5zbnj1a/wish/1878390573
