The Green Revolution in the 21st Century by Micaela Barrios https://padlet.com/mbarrios1/qd8qs6bc57fp Made with an aura of mystery en-us 2016-07-04 13:40:07 UTC 2023-03-24 03:36:23 UTC hello@padlet.com Our environment is constantly changing. There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. mbarrios1 https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115902959 2016-07-04 13:45:46 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115902959 With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing. mbarrios1 https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115903039 2016-07-04 13:47:04 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115903039 Extinct Animals Zanzibar Leopard https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115903996 One of several subspecies of leopard, the Zanzibar leopard made its home on the Zanzibar archipelago of Tanzania. It's still unclear whether this large cat is technically extinct — there are occasional unconfirmed sightings.
Cause of extinction: Locals believed the leopards were kept by witches, and aggressively hunted them. The animals were seen as evil predators that must be exterminated — and even the government was in on the campaign. In the mid-'90s there was a short-lived conservation effort but it was deemed too little, too late.

In the 1800s they were so common they were considered pests by island natives, but as the island was developed their population dwindled. By the 1950s, only 20 tigers remained.
Cause of extinction: Loss of habitat and agricultural development led to severe population decline. Conservation efforts in the 1940s and '50s were unsuccessful due to a lack of adequate land and planning.]]> 2016-07-04 14:14:55 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115904539 Global warming has become an undisputed fact about our current livelihoods; our planet is warming up and we are definitely part of the problem.

Not related to tigers, the creature had the appearance of a medium-to-large-size dog (it weighed around 30kg with a nose to tail length of almost 2 metres) but dark stripes that radiated from the top of its back gave it a tiger-like appearance. It is believed to have been hunted to extinction – this was encouraged by bounties – but other contributing factors could have been human encroachment into its habitat, the introduction of dogs and disease. The last wild Tasmanian Tiger was killed between 1910 and 1920 with the last captive one dying in Hobart Zoo, Tasmania in 1936.]]> 2016-07-04 14:29:26 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115905206 Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families.The biggest driver of deforestation is agricultura. mbarrios1 https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115905362 2016-07-04 14:32:20 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115905362 mbarrios1 https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115905441 Farmers cut forests to provide more room for planting crops or grazing livestock.

The Baiji could grow to eight feet long and weigh up to a quarter of a ton. With tiny eyes and a long thin rostrum, the Baiji had very poor eyesight and relied on echolocation to navigate and hunt for prey. Living in the Yangtze for 20 million years, the Baiji’s numbers declined drastically from the 1950s onwards. As China industrialised, it made heavy use of the river for fishing, transportation and hydroelectricity. A dwindling food supply, massive pollution and boat propeller accidents were wiping the creatures out. The restriction of fishing, establishment of nature reserves and banning of deliberate killing of the mammals in the 1970s all came too late. Although not officially recorded as extinct, no one has seen a Yangtze River Dolphin since 2002.]]> 2016-07-04 21:11:16 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115917370 Stellers Sea Cow https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115917437

It is believed that Stellers Sea Cow which grew to at least 8-9 metres and weighed around 8-10 tons, inhabited the Near Islands, southwest of Alaska and the Commander Islands in the Bering Sea. Its closest living relatives are the Dugong and the Manatee. It is believed that the mammal was tame and spent most of its time eating kelp; this, and the fact that it was unable to submerge its enormous body, is possibly what made it so vulnerable to human hunters. Within 27 years of discovery by Europeans, the slow-moving Steller's Sea Cow was hunted to extinction]]> 2016-07-04 21:14:23 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115917447 Mexican gray wolf https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115917905

Designated a threatened species for protection by the Endangered Species Act in the US, many polar bear populations will be vulnerable to extinction within the next century if warming trends in the Arctic continue at the current pace. WWF is supporting field research to better understand how climate change will affect polar bears and to develop adaptation strategies. WWF also works to protect critical polar bear habitat by working with governments and industry to reduce threats from shipping and oil and gas development in the region and with local communities to reduce human-bear conflict in areas where bears are already stranded on land for longer periods of time due to lack of ice.]]> 2016-07-04 21:30:46 UTC https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115918006 Giant Panda https://padlet.com/mbarrios1/qd8qs6bc57fp/wish/115918186

Giant pandas are currently classified on IUCN’s Red List as an endangered species.



One the main reasons that pandas have become endangered is habitat destruction. As the population in China continues to grow, pandas’ habitat gets taken over by development, pushing them into smaller and less livable areas. Habitat destruction also leads to food shortages. Pandas feed on several varieties of bamboo that bloom at different times of the year. If one type of bamboo is destroyed by development, it can leave the pandas with nothing to eat during the time it normally blooms, increasing the risk of starvation.
