Hello, my name is Mrs. Mehrin and I'm so excited to be learning all about sustainable sources of food with you.

Let's begin.

Welcome to today's lesson from the unit "Healthy eating." Your learning outcome is, I can explain why it's important to produce and harvest food in sustainable ways.

Now I know that learning can sometimes be a little bit challenging but that's okay, because it just means that we are going to work really hard together and we're going to learn some fabulous new things.

Let's begin.

So here are your five keywords for today's lesson and alongside those keywords are your definitions.

Now I am going to be referring to these definitions throughout today's lesson.

However, if you find it helpful, you can pause the video here and you can jot these down.

Off you go.

Fantastic.

Well done.

Now your lesson is split into two parts today.

Let's begin with the first part, sustainable food sources.

Now animals, including humans, need food to survive.

And Aisha says, "If the human population size is increasing," so the number of people who live on Earth is increasing, "will we need more food to feed everyone?" What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So each person living on Earth needs the right amount of food to provide them with the nutrients that they need to keep them healthy and allow them to survive and have a healthy and happy life.

Now as the human populations, the number of people, the human population size on Earth increases, the demand for food also increasing, meaning more food is needed because there are more mouths to then feed.

Now let's do a quick check-in of your learning before we continue.

So true or false? As the human population size increases, less food will be needed.

Is that true or false? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

The answer is false.

Now why do you think this is? Again, I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

The answer is, as the human population size increases, there will be more people, so more food will be needed to feed everybody.

Well done.

So Aisha says, "My parents say that the increased demand for food is making them think more about where our food comes from.

I thought that all food just came from the supermarket." What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

Sam says, "Well, most of what we eat comes from plants and animals.

If the human population size continues to grow, we might not be able to raise enough animals or grow enough crops to feed everyone." So how can we ensure that there is enough food for the increasing human population? Well, Aisha says, "I think we need to eat smaller portions of food at mealtimes." And Sam says, "I think we need to have two meals a day rather than three." Do you agree with what Aisha and Sam say? What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So neither Aisha nor Sam's idea is something that is a good way to have a healthy diet.

So you do need to eat the right amount of food for your body, and it's important to not skip meals as well, just making sure that we're being really healthy.

But there are other ways that we can ensure that there is enough food for the increasing human population.

So to make sure that there will be enough food to meet the increasing demand, we should produce food in more sustainable ways.

Aisha says, "Well, what does that mean?" Do you know? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So when we produce food in sustainable ways, we think about how we can meet the needs of people living now without having a negative impact on the needs of people that are living in the future.

So Izzy says that "Producing food in sustainable ways means growing and raising food in ways that is good for the environment, including looking after the soil." So let's do a quick check-in of your learning.

It says, how should we make sure there will be enough food for the increasing population? Is it A, we should eat less food? B, we should produce food in more sustainable ways? Or C, we should plant more crops and raise more animals? What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is B.

We should produce food in more sustainable ways.

Now plants that we depend on for food can be grown in sustainable ways by using rainwater to water them and natural compost to help them grow.

Now farmers plant different types of crops together to help keep the soil healthy.

They use solar-powered tools to help reduce harm to the environment.

Just like here we've got a solar-powered water pump.

Now special nets can be used to protect plants from insects and birds, instead of using harmful human-made substances.

Animals can be moved to different fields so the grass has time to grow back, and also animal waste can be turned into compost to help crops grow.

So these are all sustainable ways that we can help and that we can grow crops.

Let's do a quick check-in of your learning so far.

So we can produce food in more something ways to help look after the environment for future generations.

Is it A, unbreakable? B, believable? Or C, sustainable? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is sustainable.

So your first task is to use the fact files to research where different foods come from and how they can be produced in more sustainable ways.

So I'd like you to pause the video here and have a go at doing this activity.

Off you go.

Fantastic.

Well done.

So Izzy says, "Different meats come from different animals that are often raised on farms. Farmers can change which animals graze in each field to help the grass to grow back better.

This is one way of looking after the land so that food can continue to be grown for future generations." Well done.

Sam says, "Fruits and vegetables can be grown on farms. Some grow on trees.

Others grow underground.

Farmers can be more sustainable by turning animal waste into compost to help crops grow instead of using chemicals that could harm the environment." So now we are on to the second part of your learning today, which is making sustainable food choices.

Lucas says, "I wonder what I can do to help the environment when I choose which foods to eat." What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So we can choose to buy local foods that are in season.

What does that mean to buy foods that are in season? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So different foods can be harvested at different times of year.

The time when we can harvest specific foods is when we say that they are in season.

So apples can be harvested, so they can be picked ready to eat, in the UK in August and September.

And strawberries are in season in the UK in June and July every year.

So what do we call foods when they are eaten around the time they can be harvested? Is it A, in week? B, in season? Or C, in year? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is B, in season.

So Lucas says, "What happens if I want to eat food that is not in season?" What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

Izzy says, "Food that is not in season where you live could be growing in another part of the world.

This food may be transported over a long distance to you, which is not good for the environment." Now local foods don't have to travel far.

This means less fuel is used, so there's less pollution and harm to the environment.

And foods can be transported across the UK by lorry.

Other foods are flown into the UK from other countries.

And food labels often tell us where our food has come from.

So we can choose local foods that have not travelled far to get to us.

So these lettuces were grown in Cambridgeshire in the UK.

And these blackberries were grown in Norfolk, which is also in the UK.

And we can buy our food from local food markets, or even grow them at home.

This means we may have to be creative with the meals we make, depending on which ingredients are available.

Lucas says, "We use the seasonal rhubarb we grow in our garden to make a rhubarb cake every May." Well, that's a fantastic idea and absolutely delicious.

Let's do a quick check-in of your learning before we continue.

When is the best time to buy fresh local foods like fruits and vegetables? Is it A, when you see them in a shop? B, when they are in season? Or C, when you feel like eating them? I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

The answer is B, when they are in season.

Now Alex says, "My parents always throw away a lot of food each week that we don't eat.

I don't think this is good for the environment." What do you think? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So wasting food is not good for the environment because it also wastes the water and electricity used to grow, harvest, transport, and package it.

Now how can we prevent this? Again, I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

So we should only buy food that we plan to eat and try to waste as little food as possible.

So we can write a plan of what we are going to eat each week.

And planning meals is not only useful for a balanced diet but also helps us to only buy the food that we plan to eat.

Now let's do a quick check-in of your learning.

So true or false? Throwing away food is good for the environment.

Is that true or false? I'll give you five seconds to think about your answer.

Off you go.

Fantastic.

Well done.

The answer is false.

Now why do you think that is? Again, I'll give you five seconds to think about your answer.

Off you go.

Fabulous.

Well done.

It's because throwing away food creates unnecessary waste.

We should try to only buy what we plan to eat.

So here is your final task for today.

It says, create an information poster to help people to make sustainable food choices.

Give reasons why people should buy local, seasonal food and how this can reduce harm to the environment.

So I want you to think about everything that you have learned today and create your information poster.

Remember, you can always rewind the video if you need to go back over any information or any new learning that you might have come across today.

So I'd like you to pause the video here and have a go at doing that.

Off you go.

Fantastic.

Well done.

So here is an information poster that has been created.

It talks about not wasting food, buying local foods, and only buying foods that you plan to eat.

Having a look at the labels which tell us where it's been grown from.

Transporting foods and why long distances are harmful to the environment.

And also, a sign to a farm shop where you might be able to buy some of that local produce.

So now we are on to the summary of our learning today.

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.

Now you have worked really hard today.

I'm extremely proud of you.

I hope that you have learned some fantastic ways to be sustainable and to help not only the current population of Earth, but also the future populations of Earth as well.

Well done.
