Climate changes pose a threat of extinction even bumblebees

Today a gradual increase in temperature of our planet affects not only the plants but also many animal species. Recently, scientists from the us state of Massachusetts found that due to hunting and deforestation on the Earth is becoming less and less fireflies. Of course, in reducing populations of these insects played a major role and climate change, because many living creatures, sensitive to even small fluctuations in temperature. As it turned out, these creatures are all known bees which do not bring harm to anyone and slowly needed to pollinate our plant life. Climate change has already managed to inflict this insect in considerable damage, because in some regions of our planet there is almost a 50% reduction in their population.

A disappointing opening environmentalists have been discussed in the scientific journal Science Alert. Since many living creatures are hard to tolerate climate change, canadian scientists, led by Professor Peter Soroa decided to develop a way of tracking animal populations in different parts of our planet. Their idea was to divide our planet into plots of 100 square meters and to compare the number of certain animals in different periods of time. To assess the effectiveness of the developed method, they decided to see how today has changed the population of bees in comparison with indicators of the XX century.

Climate change killing insects

The choice of scientists fell on these insects due to the fact that they play a huge role in the pollination of plants. If bees suddenly disappear, humanity may experience issues with hunger, because some crops can simply cease to grow.

Bumblebees are among the best pollinators that we have. They effectively pollinate important crops such as tomatoes, pumpkins and berries, explained study leader Peter Soroa.

So, dividing the Land area into many small squares, the researchers compared populations of Bumble bees in different parts of the world in different time intervals. In particular, they were interested in the data in the period from 1901 to 1974 and indicators collected between 2000 and 2014. As it turned out, in Europe the population of bees over several decades has decreased by 17%, and in North America is 46% less.

Researchers don’t know exactly what was the cause of death of bees, but the fault of the people there is no doubt. According to Peter Soroa, scientists have long been clear that climate change is mainly caused by human activities. The fact that factories and cars release into the air huge amounts of greenhouse gases. Because of this, the temperature on our planet rises gradually, causing fires and other unpleasant consequences.
