1. What is a system?
A system is when many things work together for a purpose. Everything in the system is important and has a part to play. When a part of a system does not function properly, the whole system will break down.
2. How humans and the environment are dependent on each other.
The environment has many things to offer to us, like natural resources. We need these things to live, and without them we cannot survive. Also, plants photosynthesise, balancing out the amount of oxygen and carbon dioxide in the air, allowing us humans and also other living things to breathe. Without all these from the environment, we cannot survive. We humans also help the environment by using our knowledge to ensure that the environmental conditions are perfect. This is why humans and the environment are dependent on each other.
