As the human population size on Earth increases, more food will be needed.
To make sure there will be enough food to meet the increasing demand, we should produce food in more sustainable ways.
It is better for the environment to buy local food in season.
You should buy what you plan to consume, to avoid unnecessary food waste.

Pupils may think that all food is produced in the same way.

Explanation of how foods can be produced and harvested in different ways with differing environmental impacts.

Population - The population is the total number of something living in a particular area in a particular period of time.
Sustainable - If something is sustainable, it meets the needs of people now without having a negative impact on the needs of people living in the future.
Environment - The environment is the surroundings of a living thing, including other plants or animals and the conditions they live in.
In season - Food that is in season is only harvested at that time each year.
Harvest - When you harvest a crop, you cut and collect it from where it is growing.
