The Environment

When I remembered the nature class, the teacher said that the biodiversity on Earth was losing at an alarming rate. At that time, the teacher said that the main factor of biodiversity loss - HIPPO! The HIPPO here is actually the five main factors that humans endanger biodiversity:

H	Habitat destruction
I	Invasive alien species
P	Pollution
P	Population growth
O	Overexploitation

Putting the word together is just the hippocampus (Hippopotamus), the English abbreviation H I P P O, Chinese directly called him "Hippo effect".

In fact, we also think that the disappearance and outlook of something of LNX made or traditional culture can also prove that the five main factors of the "Hippo effect" are:

H	Habitat destruction	→The disappearance of the market
I	Invasive alien species	→Plastic toys replace natural toys
P	Pollution	→Cheap and inexpensive goods are flooding
P	Population growth	←Conversely, I hope to know that the population of LNX can be increased.
O	Overexploitation	←Conversely, I hope that through the DIY, the skill of LNX can be passed down.
