Reflections Day 2- Jiajun

Essential Question 1
What is a system?
A system is a group of organisms and environmental factors interacting with each other. A system is usually self-sustainable, but sometimes human interferences may cause the system to fall apart.
Essential Question 2
How humans and environment are dependent on each other?
Humans are dependent on the environment because the environment provides humans with resources and food. The environment is dependent on humans because humans now have the ability to shape the environment, like how the environment shaped humans tens of thousands of years ago. Humans can negatively impact the environment through deforestation, excessive hunting/fishing. Humans can also help the environment through reforestation and environmental conservation.
