Today’s class is “Biodiversity- Endangered Species.”
The extinction in the human history is divided into five extinction era. However, today is under the sixth extinction era after the fifth extinction.
In fact, extinction is natural phenomenon. However, the problem is that the sixth extinction is caused by the human beings.
When we talk about biodiversity, the important thing is genetic diversity.
Low genetic diversity causes unimaginable tragedy. The example is The Island Great Hunger and bird flu in the poultry farm.
Now we are going to make eco-friendly lip balm.
Eco-friendly lip balm has an excellent effect on moisturizing.
Students are quantifying materials.
