Everyone knows that if there is an essential living being to the human race, this being is the bee. Bees, like the bumblebee in the photography (Bombus), perform pollination, transporting the pollen between the plants. It is known that 2% of the bees in the world are responsible for pollinating 80% of the plantations on a global scale. For this reason, bees support life on Earth as we know it. Bee populations are declining. This is due to several reasons, such as: intensive agriculture, pesticide use, pollution, the introduction of invasive species, diseases and climate change.
