#OurPlanet-Episode #What's the point of watching these documentaries of modern earthly beauty? That is to give you and me a belief that there is still something on this planet worth protecting by you and me. With something worthy of protection, in addition to daily labor, there are other values beyond limited life in daily life.
#OurPlanet-Episode #Antarctic "Prairie": Beneath Antarctica's ice sheet is a world upside down compared to the barren ice surface. Beneath the ice are vast "savannahs" - algae. Antarctic krill thrives on the support of algae, and tens of billions are active on the opposite side of the frozen world. And krill feed penguins, humpback whales and other life. The terrifying group of killer whales (killer whales), like a fleet, swims neatly in the Antarctic waves, and they are the top predators in this sea area. If it is singled out, even killer whales will have difficulty catching king penguins, but the group dispatch is different, and the dexterous penguins in the water will be doomed. However, regardless of the Antarctic or the Arctic, the rise in global temperature has caused the ice surface to decline rapidly in just a few decades, and the ecology of the entire frozen world has suffered the impact of extinction. The scary and possible future is that our children may only know from the documentary that "our planet" was once so prosperous...
#Ourplanet-Episode-Jungle# The dance of the bird of paradise turned out to be a "luxury" necessary for the reproduction of life. If you can afford this luxury, you can prove that you are healthy enough. The same is true for the peacock's tail.
#OurPlanet-Episode-4-Coastal#Deepwater Hunting: Humpback whales hunt fish in deep water, they will take a deep breath, dive to the bottom of the water below the fish, and then exhale through their blowholes together to form One by one, the huge bubble strings "topped" the fish to the surface, and the small fish were forced to float up involuntarily and lost control. At this time, the whale only needs to open its wide mouth and swim upstream to have a full meal. Shallow water hunting: Unlike whales, dolphins hunt fish in shallow waters. Every time a hunting offensive is launched, there is always a dolphin as the "main attacker", which will
Circle around the school of fish, and then turn the circle smaller and smaller, until the space for the fish school is too crowded, and you have to jump out of the "hunting circle" and try to escape. Unfortunately, waiting for the desperate "fish" to leap up, it is a wide open mouth, and the feast of the dolphins begins.
#OurPlanet-Episode 5-Desert to Grassland# It is much easier to protect giant pandas than Arabian cheetahs and elephants. There are less than 200 Arabian cheetahs in the world, far fewer than giant pandas. Some endangered animals are well protected because the cost of protecting them is relatively small. Their range of activities is limited, and they can be easily controlled by delineating a small range. There is also a condition to protect those endangered species that are easy to protect, and it is also convenient to "show" their cuteness in captivity, so that humans have a more sense of control and achievement. In contrast, other animals that require a large activity area to obtain survival resources, and do not look so cute, and are inconvenient to pull out at any time to show human love, are not so lucky. Even, their living space conflicts with the living space of human beings. If their interests are to be protected, the short-term interests of the human side will be restricted and damaged. Rare animals and plants that are truly endangered are not only due to their small numbers, but the deeper reason is that the cost of protection is too high, which conflicts with the immediate short-term interests of human beings.
#ourplanet-episode 6-high seas#Why are they endangered? Because 100 million sharks are hunted every year to make shark fins; because a bluefin tuna can fetch $1 million in Japan.
#OurPlanet-Episode VII-Freshwater# The first second of the feature film is enough to make people marvel at the magic of nature. The kingfisher fishing process, which originally only happened among the electric light and flint, was accurately captured by the high-speed camera, and the slow-speed playback made it possible to see it carefully. Process.
This episode also saw that the hungry jaguar dared to attack the crocodile that no one dared to provoke. Carefully climb up the branch just above the crocodile's head, and then take advantage of the opponent's unpreparedness to bite on the only weak point of the crocodile - the throat. Don't think that the battle is over. Crocodiles are incompetent. They are also the top predators in nature. Knowing that their throat is bitten, the most effective counterattack is to take advantage of their weight and water to keep rolling over their bodies. At this moment, it is hard to say who the prey is. The crocodile is also trying to drown the cheetah with water. As long as the cheetah loosens its mouth, not only will the crocodile escape from death, but it will also be able to bite the opponent back, and the roles of prey and hunter will be reversed immediately. Between life and death, there is nothing better to illustrate than this scene: you live and die. After 20 minutes of fighting for their lives, in the end, the Jaguar persisted until the opponent collapsed, but it was exhausted. In an evenly matched survival competition, who can guarantee that next time they will still be favored by the god of victory. This is the life portrayal of "natural selection".
#Our Planet-Episode VIII-Forest# The famous bald eagle in North America was not originally a white-headed eagle in its infancy, but it gradually transformed into a typical white-headed and yellow-mouthed image when it grew up and matured. Bullying the small is the norm for eagles to forage for food. What if a one-year-old gray-headed female eagle is robbed of salmon by other adults? Then go to the mouth of the adult male eagle and grab it back. Because even a one-year-old female eagle is larger than many adult male eagles. Among the same kind, body size represents strength, and weight is competitiveness.
