The study found that how quickly species die out due to natural causes, that is, the “background extinction rate”. They found that human activity is causing species to die out 1, 000 times faster than normal.
Because human activity has negatively affected all other species on Earth, including animals and plants.
Because our world and our lives depend on the balance in nature between animals and plants.

I believe that if we take action now it is not too late to save other species from extinction. The black robin was saved from extinction when only five birds remained, so I think it is possible to save any species if we act right now.
Discuss in groups
“Human is the cancer of the Earth, and viruses are the antibiotics the Earth is taking.” I was hit deeply when I heard of the metaphor for the first time. We humans tend to think of ourselves as the master/ruler of the world, but from the Earth’s perspective, we might be just another kind of abominable creatures that need to be eradicated like dinosaurs. Do you agree with this metaphor Why or why not
As human beings, what kind of attitude should we hold towards nature
