I Have a Safari Park

The two walked slowly on the path of the Butterfly Museum, admiring all kinds of beautiful butterflies.

Looking at the popular science exhibition signs on the side of the road, I learned a lot about butterflies.

For example, the butterfly body does not have a heat-generating system, and it needs to adjust its body temperature by basking in the sun, and use its wings to adjust the temperature.

When the sun shines directly, the scales will automatically open, reducing the radiation angle of the sunlight and absorbing less heat energy from the sunlight; when the outside temperature drops, the scales will automatically close again, close to the body surface, so that the sun shines directly on the body to absorb more heat.

In this way, your body temperature is always controlled within a normal range.

The temperature control system on artificial satellites is designed to imitate the scales of butterflies.

During winter, butterflies turn their heads towards the south, like a compass, in order to observe the surrounding environment and bathe in the warm sunlight.

The famous monarch butterflies and their migration journeys are naturally also introduced.

Monarch butterflies are scientifically called monarch butterflies. They are like migratory birds in the insect world. They form large flocks of more than 100 million in August and September every year. They cross North America and spend the winter in the pine forests of California and Mexico. Return to the north.

With so many butterflies gathered together, the scene is very spectacular. The butterflies on the trees are close to each other. The densely packed and colorful butterflies dye the forest into an orange-red color.

The migration of monarch butterflies is the handover of generations, and they reproduce while migrating. When the butterflies of the older generation die, the children will relay and move forward like a frog leap. A back-and-forth migration will be completed by five generations of butterflies.

It migrates about 130 kilometers a day, and the longest journey can reach 5,000 kilometers.

Tang Xiaoxin looked at the exhibition cards and imagined the scene of their migration, and couldn't help feeling a little excited!

These fragile elves as thin as a sheet of paper have such a clear goal, using the sun as a compass and flying straight in one direction.

Flying high above the surface of the earth, enduring the pain of flying for several weeks, flying over thousands of kilometers, ending a short life, leaving behind his own offspring, and letting them carry their own genes to move forward.

What an incredible and romantic animal.

But what happened next made her feel heavy.

Over the past 20 years, monarch butterfly populations have plummeted to the point of being vulnerable or even endangered.

One reason is habitat loss, illegal deforestation, and the destruction of large amounts of coniferous forests.

Another is the heavy use of herbicides and pesticides, which reduces the milkweed they feed on.

And as the world warms, carbon dioxide levels increase, potentially making milkweed toxic to larvae.

With the increase of abnormal climate, a cold wave may cause many casualties to caterpillars and fewer butterflies to hatch.

Insects are an important component of biodiversity and also play a vital role in the functioning of ecosystems. For example, pollinators around the world generate approximately hundreds of billions of dollars in value each year, but are rarely accessible to the general public. s concern.

Recent studies have shown that the number of insects in the world has been decreasing by 2.5% per year over the past 30 years. Today, more than 40% of insect species are in decline, and about 1/3 of the species are endangered, including butterflies and moths. and the greatest reduction in bees.

Intensive agriculture on an industrial scale, overuse of pesticides, urbanization, and more frequent and erratic climate change are the main factors behind the plummeting insect population.

Next to the exhibition board, there is also a specimen of a monarch butterfly, which is quietly sealed in glass.

Compared with other flying butterflies, it looks a bit bleak.

Tang Xiaoxin stared at the specimen, thinking in her heart.

Thinking about the butterflies in this garden, if they all turned into dry specimens, it would be quite sad to think about their beauty when they were alive only in this way.

If there is no attention and protection, if this continues, for ten or twenty years, it may become a real scene in the future.

"Don't cry, let the fireflies take you to escape, the songs of the countryside will always rely on..."

Fireflies were very common in the past, and the fields at night were dotted with stars. What a romantic and beautiful scene, how can we still see them now?

Along with frogs, dragonflies, bats and other animals, they disappeared without a sound.

"Eh~"

Tang Xiaoxin sighed softly, and couldn't help but think of the local exhibition area in the zoo.

The use of ecological pest control, without pesticides and fertilizers, also provides a habitat for various animals, and humans and nature coexist in harmony.

Some hope rose again in my heart.

...

After visiting the Butterfly Museum, I came to the Cherry Blossom Forest.

A beautiful cherry blossom hangs on the treetops, and all you see are romantic pink.

A refreshing spring breeze blew, and the petals on the tree swayed slightly, bathed in the golden sunlight, and the translucent petals seemed to emit a touch of fluorescence, pink and beautiful.

Tourists walk among them, admiring the beauty of cherry blossoms, raising their mobile phones to take pictures from time to time to record this romantic scene.

Tang Xiaoxin leaned in front of the cherry blossoms, took a deep breath, and smiled: "Smell good! Is this the taste of happiness?"

Qian Keke raised his hands, closed his eyes, hugged the cherry blossom forest, and showed an intoxicated expression: "Wow, this is really great, I really want to lie down here and sleep!"

"Don't sleep, keep going!"

"I just said it~"

After a trip to the Snow Monkey Museum, the snow on the temple square has melted, and the green water in the pond seems to have been replaced from hot springs to ordinary water.

Although you can't see the snow monkeys soaking in the hot springs, it is also a pleasant thing to watch the snow monkeys play against the background of cherry blossoms.

There are snow monkeys swimming in the pool, scratching the surface of the water, the water ripples, and the beautiful cherry blossom petals also rise and fall.

Others jumped up and down on the cherry tree, swaying the branches of the cherry tree, chasing and frolic.

Occasionally pluck a petal and put it in your mouth to taste it.

Two little monkeys, hugged and rolled into a ball.

Monkey King Da Hei squatted on a rock, and glanced at the little guys playing.

She looks lonely and uneasy, but her eyes are very gentle.

After playing around for a while, a little monkey ran to Da Hei and grabbed it, as if preparing to play with it.

Da Hei was dragged a little helplessly, and helped the little monkey to comb the fur.

The little snow monkey who was groomed narrowed his eyes and looked very comfortable.

But after combing it twice, Da Hei's movements stopped. I combed my hair just now, I just didn't want the little guy to make trouble with his perfunctory behavior.

Seeing this, the little snow monkey raised its head, as if expecting Da Hei to continue to groom it.

Da Hei jumped off the stone and changed his position to stay.
