  By definition, a genetically modified organism (GMO) is one where genetic characteristics of one specie is modified by insertion of an altered organism gene of the same species or a gene from other organisms using genetic engineering. When the gene is taken from the same species it is called intragenic modification where as a gene from a different organism is called transgenic modification. The major criticisms of genetic engineering in food production have been in the areas of potential human health effects, environmental and other possible socioeconomic effects. Genetically modified foods first appeared in the food market in the 1960s (Uzogara, 2000). In 1967, a new potato variety called Lenape Potato was bred for its high solids which made it appropriate for making potato chips. Two years later, the Lenape potato developed a toxin called solanine and it was withdrawn from the market by the United States Department of Agriculture.

The covid 19 pandemic is wrecking havoc in countries across the globe, causing a global health crisis and forcing the economies to slow down due to the strict quarantine measures, with further consequences ranging from closed boarders, scarce hand sanitizers, to house arrests to ensure social distancing measures. Bad as that may be, the pandemic has impacted the environment in a very intriguing way.  The carbon dioxide emissions and human mobility have been reduced leading to improved air quality lessening on the pollution in the air  due to commuting because of  “work from home” policies, industries and aviation being  on operation halt , among others .   According to Randolph Bell, Director of the global energy center explained in the Atlantic council that the economic recession linked by the virus is likely to cause a drop in the carbon dioxide emissions this year. For example, NASA satellite indicated a 25% reduction of carbon emissions in China after 4 week...
