Today, a gradual increase in our temperatureThe planet harms not only plants, but also many species of animals. More recently, scientists from the US state of Massachusetts found that due to hunting and deforestation on Earth, there are fewer fireflies. Of course, climate change also played a large role in reducing the population of these insects, because many living creatures react sharply even to small fluctuations in air temperature. As it turned out, well-known bumblebees belong to such creatures, which do no harm to anyone and leisurely pollinate the plants necessary for our lives. Climatic changes have already managed to cause significant damage to these insects, because in some regions of our planet there is an almost 50% reduction in their population.
The disappointing discovery of ecologists wasnarrated in the science publication Science Alert. Since many living creatures are difficult to tolerate climate change, Canadian scientists, led by Professor Peter Sorae, decided to develop a way to monitor animal populations in different parts of the world. Their idea was to divide the territory of our planet into areas of 100 square meters and compare the number of certain animals at different time periods. To assess the effectiveness of the created method, they decided to see how the bumblebee population has changed today compared with the indicators of the 20th century.
Climate change kills insects
The choice of scientists fell on these insects because ofthat they play a huge role in pollination of plants. If bumblebees suddenly disappear, humanity may experience problems with hunger, because some crops may simply stop growing.
Bumblebees are considered one of the best.pollinator insects that we have. They efficiently pollinate important crops such as tomatoes, pumpkin and berries, ”Peter Soroe, the study leader, explained.
So, dividing the Earth into manysquares, scientists compared bumblebee populations in different corners of the planet at different time intervals. In particular, they were interested in data from 1901 to 1974 and indicators collected between 2000 and 2014. As it turned out, in Europe, the bumblebee population has declined by 17% over several decades, while in North America it has dropped by as much as 46%.
Researchers do not know exactly what becamecause the death of bumblebees, but there is no doubt about the fault of people. According to Peter Soroe, it has long been clear to scientists that climate change is mainly triggered by human activities. The fact is that factories and cars emit a huge amount of greenhouse gases into the air. Because of this, the temperature on our planet is gradually increasing, which causes fires and other unpleasant consequences.

How to save insects from death, scientistsIt's not clear yet. But, thanks to the study, scientists have learned that most bumblebees die in dry areas. Perhaps someday they will be able to be saved by growing a population in a territory with more suitable environmental conditions.
