“When whales were at their historic populations, before their numbers were reduced, it seems that whales might have been responsible for removing tens of millions of tonnes of carbon from the atmosphere every year.”

  1. How do old growth forest change climate, for the answer ask Viktor Schauberger. The two demonic actions of man that started climate change were the slaughter of the whales and the destruction of the earth old growth forest.

  2. Can y'all help me out with these answers

    1. Describe three or more specific examples of how whale activities have caused direct changes in so many other populations within their ecosystem:

  3. There has to be a balance. You cannot just state that more whales is better. Where does it end? At some point, there will be too many. The best solution is sensible whaling.

  4. Just let me be honest, I Hate humans and very disappointed of all what humans are doing .. I prefer loving a TREE or ANIMAL then loving crueler greedy creature!!!

  5. All of the destruction done by most of the human race was done for greed without much thought, if any, of what would lie ahead in the future. It's about living in harmony with nature, in return, it will be bountiful and plentiful.

  6. A beautiful way of entering into the spiritual feeling of surrender. No gods or other burdensome religious appendages required.
    “Though unknown, one can tune in to the divinity in the world by feeling the wonder of nature.” (A. Parthasarathy. Gita, 2.29)
