The environment
There are 6.4 billion people in the
world to share all its resources.
We don’t want to use up all
these resources for future
generations.
We need to consider the
impact our decisions have on
our environment.
We have to think about our
social, economic and
environmental responsibilities.
We need to become informed decision makers.

Reuse – rejected food
Supermarkets throw out a lot of unused bananas because
they don’t think people will buy them. The bananas might be
overripe or damaged.
Respect Organics make a range
of organic cakes including
banana cake. Ripe bananas are
needed for the cake recipe so
Respect buy these reject
bananas at a good price. It
doesn’t matter if parts are
bruised – these can be cut off.
How could you do this with your recipes?

Reduce – portion sizes
Check the size of portions of fatty or sugary foods you eat.
Use the proportions of the eatwell plate as a guide to help
you maintain a balanced and healthy diet.
Reduce the amount of
processed food you eat.
Ready meals and tinned foods
often have a high amount of
salt and sugar in them.
Boys aged between 11 and 14 should be taking in about
2,200 calories a day. Girls aged 11-14 should be taking in
roughly 1,845 calories a day.
Try to make sure the calories you take in contain
all the major food groups in the right proportions.

Reduce – energy
Eco-friendly cooking involves using sustainable ingredients,
but you could also reduce energy used in preparing your food.
Think before using electrical
equipment. Could you do that
by hand?
Think before you cook yourself
a snack. Could you eat
something raw?
Think before you put 3 or 4
pans on the cooker for your
dinner. Could you cook
everything together?
