The bees they are one of the most important pollinating insects. Without them, a good part of the flora would end up becoming extinct in a few years, and with it, there would be many animals (including humans) that would have many problems getting food. There are those who say, in fact, that if they are extinguished, the following would be us, the people, but honestly, I believe that the situation would not be so serious. Why? Well, there are many plants that can be reproduced by cutting, and without a doubt the fact that this can be done, it will surely allow us to feed ourselves.
Now, it cannot be ignored that bees they have a very important role in the ecosystem. And due to global warming they have more and more difficulties to do what they do best, which is to pollinate flowers so that new generations of plants can exist.
Of course, there are many pollinating insects, such as ants, cockroaches, dragonflies, etc., but bees are among the most at risk of becoming extinct right now. The reasons are very diverse: use of pesticides, parasites, invasion of other species of bees, loss of habitat ... And also the global warming, which is affecting the rain regime around the world, worsening droughts in many places, increasing global temperatures and putting the lives of plants themselves at risk.
A report, commissioned by the United Nations, reveals that by the year 2050 humanity could have serious difficulties to feed itself, due to the decrease in the population of bees and other insects that are responsible for pollinating flowers (such as hummingbirds or bats).
However, not everything has to be so negative. In fact, this is a situation that can be prevented very easily if we take care of the environment with natural products. And if you also have a garden, let wild flowers grow at least in a corner, or grow your own. Thus, you will attract bees that will help your plants to bear fruit.
As you can see, these insects are very necessary. Let's take care of them so they can continue their work.
