Thinking and sharing
Which of the “green truths” surprises you most Give you reasons.
Are you aware of any other “green truths” that are not true
False “Green Truth”
Hybrid (混合动力产品) is better
Hybrid vehicles are a better choice for the environment than a standard vehicle. Again, this is a common false statement about green living. The truth is that Hybrid products, such as cars, take more energy to produce than they conserve. They are like bottled water in that respect. It takes more energy to make the item that is supposed to be green and environmentally better than the item itself gives back.
It is an unethical practice where companies mislead consumers by claiming to be environmentally friendly or sustainable.
It may involve simply changing the packaging of existing product while continuing to use unsustainable ingredients or practices.
