claim: Each year sees the disappearance of thousands of plant and animal species which we will never know, which our children will never see, because they have been lost for ever.
evidence: The temperature of the photosphere is approximately 6,000 K, whereas the temperature of the corona reaches 1,000,000–2,000,000 K. The high temperature of the corona shows that it is heated by something other than direct heat conduction from the photosphere.
