Squirrels especially love pine nuts. When they can't finish eating, they dig a hole in the ground and bury the pine nuts, so that they can eat later. It buried a grain here, buried one grain there, and buried nearly a hundred grains in a few days. Who knows that it has been buried for a long time, and many places where the pine nuts were buried have been forgotten by the squirrels and can no longer be found. These pine nuts sprouted and grew into a tall pine tree under the nourishment of rain.
 
  The squirrel was originally greedy for pine nuts, but did not expect to unwittingly make a pine tree.
 
  It turns out that everything in the world is not independent. Sometimes it is for others and for others, for others to be able to fulfill others.

  The world's largest animal whale is more than 30 meters long, and the blue whale weighs nearly 200 tons.

  After reviewing the information , some of the world's most powerful animals often rely on some of the tiniest animals to survive, such as a blue whale eating 4 million krill a day.
 
  I suddenly understood: a small is small, but 100 million small or small?

  Flies often come into dirty places such as septic pits and garbage dumps, but they are not sick. The secret is that flies work extremely efficiently: from feeding, processing to absorbing nutrients until they discharge waste, only 7-11 Seconds. The germ has just entered the fly, and it has not been able to multiply in a large amount, and it has been quickly expelled from the body.
 
  Don't let the germs have a breathing time, drain it as soon as it enters; don't let corruption have a chance to breed, and eliminate it when it comes out. The fly may bring us some inspiration.

  The weapon of the bee sting is the acupuncture of the tail. The acupuncture is to inject the venom into the human body through the venom gland. However, because the acupuncture, the venom gland and a part of the internal organs are closely connected, once the bees are pulled out, the internal organs will be pulled out together, so that the bees will not survive.
 
  If the acupuncture is only connected to the venom gland, the bee can swear unrestrictedly. This arrangement of nature is truly unique: if you marry someone else, you will be jealous of yourself.
