    • Brazil is one of the largest producers of agricultural crops such as soy and alongside it, is one of the largest consumers of pesticides, fungicides and herbicides. This results in the need to reformulate these chemicals as soon as biennially. One of the reasons is because of the directional selection that occurs favoring the alleles with a selective advantage. Another reason is due to the rampant deforestation. Suggest how the latter can lead to the frequent need for agricultural chemical reformulation. [2m. Date of creation 220719]
    • Some biotech companies are starting to genetically modify trees proposing it as a solution to climate change. One such example is that of the company known as Living Carbon which seeks to increase the grow rate of trees such that they can offset the anthropological carbon dioxide emissions. Suggest what is a potential concern with such an advancement. [1m. Created 220304]
