mean for us? Bees pollinate 70% of human food crops‚ which supply 90% of the world’s food. If bees die out‚ foods such as apples‚ pears‚ peaches and so many more will follow. The agriculture industry will be devastated as a result. The precious pollination provided by bees is estimated to be worth $10 billion to $15 billion to the agricultural industry a year. The strain on our economy would be catastrophic‚ increasing costs for food production leading to increased cost for food. However‚ there are

A World without Bees! What is causing pollinator declines in the northern hemisphere and what are the potential implications for South Africa? The world depends heavily on pollinators. Although the bee is not the only pollinator‚ pollination is the bee’s main niche‚ so without bees‚ there would be an enormous decrease in plant life. Plants that are not pollinated will not produce fruits and seeds. And would therefore cause and end of animals and human life. Albert Einstein said: “If the bee disappeared

Bee The bee is a vital part of human existence. They pollinate‚ giving life to plants‚ animals‚ and in turn‚ man. If they were to die out‚ the human race would follow suit in a mere matter of years. 65% of all flowering plants require bees for pollination‚ and the percentage being higher for the major crop plants‚ like corn and wheat. These crops account for $47.1 billion every year. Honey bees are responsible for one-third of the food we eat‚ meaning no bees equals no food. The first signs of danger

Bees contribute to our society economically‚ ecologically and biologically. They are the species that really make everything the way it is for us. Bees contribute economically because the crops and plants we have are only here because of the pollination of the bees. Bees pollinate about 90 crops and a third of our food supply. Bees are central to the systems that support food production for human beings. An international study of 115 food crops grown in over 200 countries showed that 75% of the

is a fantastic arrangement - as long as bees stick around. As bees became more and more successful‚ and better integrated with the farming lifecycle‚ other species started to die out‚ until eventually bees are now responsible for a third of all pollination in America‚ with similar figures elsewhere. Around such a contentious issue one thing is clear: we need bees. Rudimentary foodstuffs like apples‚ pears‚ cucumbers and strawberries are dependent on farming and bees to keep ticking over at the rate
