Many people are sure that bees are the only onesBees of their kind, and they are all the same. Only now in the world there are about 21 thousand species that live in all corners of the world, except Antarctica. These insects sting painfully, but are of great benefit to humanity. A large number of people contain them in their home areas for honey, which has many useful properties and does not have restrictions on the shelf life. Also, these insects spread pollen of plants and green our planet, providing us with plenty of food. As you can see, these creatures are very important for us, but there is bad news - recently in the USA a record extinction of bees was recorded. Do you already guess what the consequences will be?
About a record number of extinct bees toldGizmodo Edition. Journalists learned about this by looking at the results of an annual survey conducted by researchers from the University of Maryland (USA) among more than 3,000 beekeepers. In total, they own 276832 colony of bees and every year inform scientists about all the important changes that are happening in the life of these insects. It turned out that from April 2019 to April 2020, beekeepers in the United States lost 43.7% of honey plants.
Usually, bees die in large numbers in winter,during the cold weather. But this time, the proportion of bees extinct in the winter period was only 22.2% - in previous years the percentage was at least 6.4% higher. Most bee deaths occurred in the summertime - scientists did not observe such mortality for as long as 14 years. The survey showed that last summer 32% of the bee population died, which is 10.4% higher than the average.

Effects of heat
The main cause of high bee mortalityThe abnormal heat of the summer of 2019 is considered. Then the near-Earth satellites of the European Agency, launched as part of the Copernicus program in 2014, recorded a record high temperature - the jump occurred in July. High air temperature could affect the reproduction of bees, as well as lead to their starvation. The fact is that the flowers, the nectars of which they feed, bloomed at different times and the insects were clearly not ready for such changes.
My colleague Artem Sutyagin recently wrote about how bees breed without mating.
Also, throughout the year, researchers noticedan increase in the population of varroa (Varroa) - parasitic ticks that penetrate the organisms of honey bees and literally live at their expense. They suck out energy from insects, eating their fat bodies. Most often, parasites are attached to the sinuses between the wings of the bees, on the back of the abdomen and between the legs. Most bees cannot get rid of parasites on their own, but individuals in some colonies can shake them off from each other.
Do not forget that the life of beesaffects the pollution of our planet. Relatively recently, in Argentina, bee nests made of plastic garbage were found. This material is clearly unsafe for insects because dead larvae and adults were found inside plastic nests. It may well be that the presence of such dwellings also affected the survivability of tiny creatures.
The consequences of the extinction of bees are very deplorable, becausethat humanity is highly dependent on their activities. According to researchers at the University of Maryland, in the United States, bees pollinate crops for about $ 15 billion annually. It turns out that about a third of the food that we eat from day to day, received through the life and work of bees.

The problem of extinction of bees, like many othersliving creatures can only be solved by cleaning our planet from debris. However, maybe everything is heading towards a high-tech future, when people will be half robots, and special devices will be used for pollination of plants?
