What are ‘in season’ foods?
Foods grow best at a particular time of year
when they are in season
Fruits and vegetables that are in season are
fresher and tastier
Eating in season fruits and vegetables is good
for the environment and good for us!

Seasonal fruit & veg
is good for the environment
Often cheaper because they come from farms nearby, so
less transport and fuel is needed
Transporting foods requires fuels
which are bad for the environment
When foods are out of season in Scotland,
we have to transport them from all over the world

What are food miles?
The distance a food travels from where it is produced to
where it reaches the consumer
Strawberries are out of season in winter in Scotland so they
come all the way from South Spain…
that means a lot of food miles!
The higher the food miles,
the worse it is for the environment.

76% of apples consumed in the UK are from overseas.
When apples are out of season in Scotland, they
can come all the way from USA…
How are the apples transported?

Why are lots of food miles bad?
 Planes, boats, trucks and trains used to
transport food burn lots of fuel and
energy
 When fuel is used, carbon dioxide and
other greenhouse gases are produced
 An increase in these gases in the
atmosphere causes global warming – the
steady rise in the earth’s temperature.

Why is global warming bad?
 The rise in the earth’s temperature could hurt
many people, animals and plants that can’t
adapt to higher temperatures
✗ Coral can start to die
✗ Some fruit & veg can’t grow properly
 Higher temperatures could also lead to more
dangerous weather conditions
✗ More cyclones and droughts,
which makes growing food harder
