●Data released recently by the U.S. National Park Service shows that two wildfires in California this year destroyed between 2,261 and 3,637 giant redwood trees. In addition, last year, a wildfire in California destroyed between 7,500 and 10,000 redwood trees. This means that in the past two years, California wildfires have destroyed nearly one-fifth of the giant redwoods on Earth. (Source: CCTV News)

New findings

●According to the website of Germany's Frankfurter Allgemeine Zeitung, scientists from NASA calculated that the oxygen-containing atmosphere on Earth cannot continue to exist. Scientists say that the oxygen content in the Earth's atmosphere will be very low in 1 billion years, making it impossible for aerobic organisms to survive. The reason for the drastic change is that the sun will become hotter and hotter in the future, and carbon dioxide will absorb heat and decompose, causing the carbon dioxide content in the atmosphere to drop sharply. Photosynthetic organisms (including plants) will not be able to survive and will no longer produce oxygen, causing a sharp decrease in oxygen. (Source: Reference News)
