The song "Blood of the Earth" by Hawkwind describes the destructive effects of human activities on the planet. The earth is described as barren and lifeless, with flood waters and mud dominating the landscape. The lyrics suggest that the earth's resources have been depleted and its natural balance has been thrown off by human actions. The "coagulated scabs of earthly blood" and the "burning dust" are references to the damage caused by mining, drilling and industrial activities that have scarred the earth. The crops failing and people wailing reflect the dire consequences of this damage, such as famine and displaced communities. The last line, "as into our coffin drives the final nail", suggests that if human beings continue to exploit the earth without regard for its limits, we will ultimately bring about our own demise. The song is a somber warning about the need to take care of our planet and to live in harmony with nature, lest we destroy ourselves along with the earth.
