The world is a very wonderful and interesting place that is full of nature.
Plants and animals have important parts in the ecosystem.
Even small insects have their own roles.
Do you know that over 60% of all the known species on the earth are insects?
That’s true.
Many studies are ( Ａ ) and scientists are getting worried about the results.
According to a study in Germany, over 75% of flying insects have decreased.
There are many reasons, such as air pollution, water pollution, ground
pollution, a lot of chemicals to save plants,
and so on.
Some insects are bad for us because they eat a lot of fruits and vegetables.
However, others are useful for us.
Actually, they pollinate most of the plants on the earth.
If the number of insects decreases, the number of plants will decrease,
too.
Also, many of these insects are food for birds and other animals.
What will these birds and animals do without food?
They cannot survive. Insects are small, [ ① ].
How can this problem be solved?
Some people are working to solve this problem.
②They say that this problem can be solved 【 understand / insects / of /
the importance / people / when 】 .
Insects are necessary for humans.
One example is a department store in Osaka, Japan.
In 2020, it started to raise about 50,000 bees on top of the building.
The bees search for flowers around the department store and collect pollen
from flowers.
The bees move from flower to flower when they collect pollen.
This helps pollination.
Thanks to the bees, some of the local plants can grow, and bees can make
honey in their hives.
The department store shows the customers the bees and sells the honey.
Their goal is to tell the local people about the importance of bees and
the environment.
We have another good example.
At a high school in a big city, students are also taking care of bees
because they want to share the importance of bees with other people.
The students learned the important relationships of human beings and nature.
They made picture books. So children can learn the relationships from the books.
More and more people are starting to understand the serious problem
and scientists are working together to take action.
Insects are useful for us.
What can we do?
We can learn from other examples, raise more insects, and increase plants.
Now, let’s continue helping each other to protect the environment! |
