1) The UNCTAD report that is cited actually has the following text:
"The views expressed in the articles contained in this Review are the personal views of the authors and do not necessarily reflect the views of their respective organisations and institutions."
Many of the authors have ties with the organic industry (see https://thoughtscapism.com/2015/09/21/myth-un-calls-for-smal...)
2) Organic food has less pesticides exposure.
Not necessarily as organic agriculture also uses pesticides (naturally occuring ones). Though they tend to degrade quicker than synthetic ones, they are not as effective and need to be applied more often. Also the use of copper sulfate is allowed, which doesn't biodegrade and builds up in the soil.
The following is also completely rubbish
"Yes, pesticide residues are regulated by the U.S. Food Quality Protection Act, but the tolerance levels assigned for some pesticides pose potential health risks, even though they are considered “allowable.”"
3) Organic foods are more nutritious and taste better.
Nope. The article just cherry picks a few studies. Following meta study comes to conclusion that organic food is not more nutritious

4) Organic foods help achieve biodiversity and soil fertility
Maybe on the area farmed, but it tends to not be as efficient as conventional farming, so increase acreage is needed which reduces biodiversity.
Regarding soil fertility, GMOs have actually helped thanks to no till agriculture.
5)Organic foods have no GMOs.
GMOs actually can help reduce pesticide use (but its not a silver bullet)
