Lots of people understand the word environment only as a overall environment in the world  such as ecological environment. But in my point of view, a small environment is more important such as living environment mentioned in “minimalism”. Both of ecological and living environment may change our life without us being noticed. Children have common point with who they have been brought up is an evidence. Therefore the living environment can affect people’s physical and mental health, and also the health of ecological environment.

   To start with, the living environment will affect people’s physical and mental health. As YAMASHITA HIDEKO said in “Danshiri”, “When the living environment is filled with unnecessary items, it is like a lot of unnecessary thoughts in the heart. They will become a kind of stress and affect the mental health of the residents.” People always think they will use their unwanted items one day or items are still useful and brand new. In fact they will hardly or never use the unwanted items again. This is a kind of anxiety future has bought to people. However, we do not need to prepare so muchstuff for a completely unknown situation to make us feel safe in daily life. Moreover to keep many items tidy need a lot of time and energy, most of people would choose to leave a mess of unwanted items. A lot of bacteria and dust can be stored in unwanted items which will have a negative effect on people’s health day by day. Also, a punch of mess may influence people’s emotion. People can feel upset and impatient in a mess. Thus, living environment can have an influence on both physical and mental health.

Furthermore, the living environment will affect the health of the ecological environment. Buying many items that make you feel uncomfortable and unnecessary will encourage businesses to produce more of these items. Business care more about data then why people buy things companies sell. Buying unnecessary product is a way to encourage company to produce more unnecessary product. This may lead to a waste of resources and over-development of the natural resources. Ecological environment balance may be broke caused by buying unnecessary product.

In conclusion, living environment can effect people’s physics and mental health, ecological environment can be effected by people’s behaviour.
