BBC 6 minute English-Is there a future without bees

Transcript of the podcast

Note: This is not a word-for-word transcript

.Neil: Hello. This is 6 Minute English from BBC Learning English. I’m Neil

?Sam: And I’m Sam. How are you, Neil

.Neil: I’ve been as busy as a bee this week, Sam

!Sam: Oh, don’t you sound like the bee’s knees

!Neil: All right, Sam, there’s no need to get a bee in your bonnet

.Sam: As you can hear, English is full of idioms involving bees

Neil: But the sad truth is that bee numbers are declining at an alarming rate and in some places disappearing altogether

.Sam: And this has serious consequences for humans

Neil: Today, one third of the food we eat depends on insects to pollinate crops, fruit and vegetables

Sam: But bees are in trouble. In some European countries up to half of all bee species are facing extinction, placing our food supply chain at risk

Neil: Bees are vital in pollinating hundreds of crops, from apples and blackberries to cucumbers. In fact, almost all plants need insects to reproduce – which is my quiz question – of the world’s top 50 crops, how many rely on insect pollination? Is it
?,a) 35 out of 50
b) 40 out of 50? or
?c) 45 out of 50

.Sam: I reckon those busy bees pollinate b) 40 out of 50 of the most common crops

Neil: OK, Sam, we’ll find out the answer later. Now, if you think back to your school biology lessons, you may remember that plants and flowers contain both male and female reproductive parts inside

Sam: But what exactly is going on when bees pollinate a plant? Here’s Claire Bates from BBC World Service programme People Fixing the World to remind us

Claire Bates

What is pollination? All flowering plants need it to reproduce. Pollen is moved from the male part of a flower to the female part of a flower, then fertilisation can happen causing fruit to grow. Some staple crops such as wheat, rice and corn are pollinated by the wind however many plants don’t release their pollen easily and this is where insects, and especially bees, come in. As they collect nectar to eat, pollen sticks to them and they carry it from flower to flower

Neil: Pollination is the process in which pollen is taken from one plant to another so that it can reproduce. This is the important work done by bees and insects

Sam: Only after pollination can the next process occur – fertilisation – when the pollen carried from another plant fertilises a female ovule to make new seeds

Neil: Fertilisation occurs in all flowering plants, some of which like wheat, potatoes and rice are staple crops – food that is eaten in large amounts as part of a community’s daily diet and provides a large fraction of their energy and nutrient needs

Sam: Fewer bees reduces pollination levels, meaning fewer new seeds are created and fewer crops grown

Neil: But it isn’t just the decline in bee numbers causing a problem. Like us, bees need to rest and this has led some to come up with creative new ways of supplementing bee pollination

Sam: One such innovator is Keren Mimran, co-founder of agro-tech company, Edete. Here she is, explaining how dropping pollen from drones can pollinate crops, giving a helping hand to hard-working bees

Keren Mimran

How come our food security is so much dependent on an insect that we cannot really control? We can bring the bees to the orchard or to a field but we cannot control their behaviour. They do not come out of the hive when it’s raining or when there’s heavy wind, they work only during daytime. There must be a possibility of developing a mechanical solution to the pollination challenge

Neil: Keren Mimran speaking on the BBC World Service programme People Fixing The World. Bees’ behaviour can’t be controlled – when it rains they won’t leave their hive – the structure where bees live, either built by people or made by the bees themselves

Sam: So Keren’s company has developed drones to drop pollen on her orchard – an area of land on which fruit trees are grown

Neil: The need for these high-tech solutions reflects the seriousness of the pollination problem for food security -everyone getting enough affordable and nutritious food to meet their daily dietary needs

Sam: I had no idea bees were so important, Neil. Maybe I underestimated how hard they work

Neil: Ah, you mean today’s quiz question. I asked you how many of the top 50 world crops rely on insect pollination

.Sam: And I said b) 40 out of 50 of the top crops

Neil: And you are right! They certainly are the bee’s knees when it comes to pollinating plants

Sam: So in today’s programme we’ve been hearing about the important role bees play in pollination – transferring pollen from plant to plant, necessary for the next stage of fertilisation – producing new seeds and fruit inside a plant

Neil: Bees and insects play a vital role in growing the world’s staple crops – food which, eaten in large amounts, makes up the majority of a community’s daily diet and meets their nutrient needs

Sam: So bee numbers are directly linked to the issue of food security – everyone getting enough affordable, nutritious food to meet their dietary needs

Neil: Which explains why, when bees won’t leave their home – or hive – some people have started using drones to pollinate their orchards – land growing fruit trees

!Sam: And that’s it for this edition of 6 Minute English. Bye for now

!Neil: Goodbye
