This time, I would like to talk about the milk that many people love. Which milk do you buy?
I’m sure most people buy milk.
Milk and the environment
Buying milk is a casual act, but we vote for the company and show it is in demand.
Before you buy it, think about its environmental impact.
Milk uses land and water resources, has a large impact on the environment, and promotes global warming.
Just changing the drink will change the load on the earth.

Milk and greenhouse gases
The graph above shows the world average data from a survey by Oxford University.
According to it, greenhouse gas emissions emit about three times more than plant-based milk when producing a glass of milk.
Almond milk has the lowest greenhouse gas emissions.
Milk and land
According to this study, 650 square meters of land are needed to produce one glass of milk daily for one year.
This is equivalent to two tennis courts, ten times more than the same amount of oat milk.
In terms of land, all plant-based milks are just as low.
Milk and water resources
Almond milk consumes more water than soy milk or oat milk.
3.8L of water is needed to grow a grain of almond. You need 74 liters of water for a glass.
This is more than a regular shower.
Rice milk is also relatively water consuming, requiring 54 liters of water per glass.
However, both almond milk and rice milk consume less water than milk.
Milk has many environmental impacts such as greenhouse gases, land and water resources.
When food is produced, the magnitude of climate impacts has proven to be very different.
This data comes to my mind every time I buy almond milk occasionally in the supermarket.
I used to buy boxed almond milk at Costco, but now I’ve stopped buying it and the number of drinks has really decreased.
I drink soy milk every day, but I would love to buy oat milk if there are it in supermarkets in Japan.
