Especially after the years preceding the Industrial Revolution, a significant number of animals have been extinct. Since so many have been extinct, these are the most incredible and charismatic animals that need to be highlighted as a reminder that protecting animals is an outmost necessity.
1. The Baiji River Dolphin The Baiji River Dolphin was a dolphin living in the river and its only native is found in the Yangtze River, China. The species is considered extinct functionally speaking since 2006, as a scientific survey to count the population indicated that there are no survivors. The animal was very widespread before, with 6000 approximately living in the river up until 1950s. However, the industrialization of the area, the fishing industry and the various hydroelectric dams caused the population to shrink in the subsequent decades and resulted in having only a few hundred animals in the 1980s. These animals were big enough. They had a length of approximately 7 to 9 feet and they weighed almost 500 lbs. They could live in the wild more than 24 years and were able to speed up to 37 miles per hour when they were swimming.
