Theobroma cacao (cacao) is the tree that produces seeds that are turned into chocolate. These trees provide many poor people in the tropics with some cash income. However, these farmers face many obstacles to production of their crop, including temperature and rainfall changes caused by atmospheric CO2 increases, and many diseases and pests. Analysis of the cacao genome showed that there is some (but not a lot) of genetic variation in the 10 major varieties. Which of the following strategies would be most useful in the long term in reducing pressures faced by cacao farmers? Select one: OA. Fertilize the trees in closely spaced areas and add fungicides and pesticides to eliminate pests. OB. Plant more trees in the temperate zone. OC. Plant trees farther apart so that disease transmission rates from one tree to the next will be lower. OD. Crossbreed cacao strains that produce high-quality cacao beans and ones resistant to a disease. Clear my choice

Fertilizing the trees and adding fungicides and pesticides might help in the short term, but it does not address the long-term issues of climate change and genetic variation. B. Planting more trees in the temperate zone might not be suitable for cacao trees, as Show more…

Environmental impacts of chocolate The production of chocolate can have intense environmental impacts. Select all of the following ways that chocolate production can negatively impact the environment: - Replacing native vegetation with cocoa tree monocultures increases the overall rate of plant transpiration, allowing a cooling effect on the climate. - Clearing forest to plant cocoa trees reduces atmospheric carbon dioxide levels and greenhouse gases. - Farmers will plant monocultures of cocoa plants, reducing the biodiversity of ecosystems. - To keep up with the demand for cocoa beans, farmers clear cut land to plant cocoa plants. - Fewer trees because of deforestation means less long-term carbon storage, increasing atmospheric carbon dioxide levels. - Burning plant wastes from deforestation increases greenhouse gases in the atmosphere. - Because older trees yield fewer pods, farmers continue to clear cut land to plant more cocoa plants. - Farmers will plant monocultures of cocoa plants, so there are fewer chances for disease because of the decrease in biodiversity. - Farmers clear cut land to plant cocoa trees, allowing sunlight to hit the ground, which increases the biodiversity of soil microbes.
