The simplicity that is pollination is one that we as a race would have a hard time living without. Not only because of the food yield‚ but also the economic impact the industry has had in the last century. The act of pollination has been industrialized for a while now. Some people have even linked the act back to ancient Egypt around 2400 years ago (History of Beekeeping‚ 2010). Since then the practices have gradually moved into the United States and we have begun to see just how important these

In the mid-twentieth century‚ there were high uses of toxic pesticides--namely DDT. Overtime these pesticides would have toxic effects on the environment and organisms. An environmentalist named Rachel Carson was greatly bothered by this and wrote the book Silent Spring explaining the toxicity of insecticides and their effects on life. Carson explained the effects that insecticides were having on life at that time‚ and the effects that would happen in the future if insecticide use continued. Silent

affect the environment is by making it a monoculture in our ecosystem. “When GM crops are planted‚ generally in a monocrop fashion‚ many heritage seeds are no longer used. The nature of GMOs means fewer weed flowers and‚ therefore‚ less nectar for pollinators. “ (Emily Glass.) Having a monoculture can result in quicker spread of diseases and can cause an economic disaster. They’re many possible consequences of genetically modifying foods but most of the possible consequences are predictions or theories

Why Bees are the Bee’s Knees: The Economic Importance of Bees As Pollinators Introduction Bees have indirectly contributed to the United States’ economy for hundreds of years. Dozens of industries have flourished and thrived off the backs of these tiny insects‚ and without them‚ the average American lifestyle would not exist. As a society‚ we are dependent on bees to pollinate our crops and provide us with honey‚ which in the U.S. alone was worth $317 million in 2013 (“Honey Industry Facts”). Bees

Genetically modified organism is one of the least talked about topics in relations to current ongoing problems. For those who don’t know exactly what a genetically modified organism (GMO)‚ a GMO is known as an organism that has been genetically modified this genetic material has been reformed to improve product quality. GMOs are used for many things although the best-known use is for genetically modified foods. According to the World Health Organization “Genetically modified (GM) foods are foods

Joker (2000) stated that the seeds should be stored in dry‚ airtight container as this will allow the seeds to retain viability for up to two years while at ambient temperature up to six months. Besides‚ the seed can be also dispersed by using the pollinator agents and the weather may affect the germination of seed. It is a flexible and fast-growing plantation tree species as it can be grown best on deep‚ moist‚ alluvial sites and regularly flooded areas. The most important circumstance for the optimized
