Final answer:
The specific number of food and food-related businesses in ZCoB in 2020 is not provided. Nonetheless, excerpts suggest an increasing trend in food production and food business employment, amidst a global hunger crisis and significant projections for future food demand based on current population growth and dietary tendencies.
Step-by-step explanation:
The question regarding the number of food and food-related businesses within Zingerman's Community of Businesses (ZCoB) in 2020 is not directly answered in the provided information.
However, we can address the broader context of food business trends and food security based on the excerpts. The report by Berners-Lee suggests a significant increase in edible crops by 2050 if current dietary trends continue.
Meanwhile, projections by Caroline Krafft indicate an increase in food production and housing units, with food production growing more due to food-specific growth. Nevertheless, it is important to note global issues such as food insecurity, with over 810 million people experiencing hunger in 2020 and a global hunger crisis exacerbated by the pandemic and supply chain issues.
Employment in food preparation and related sectors may see varied changes, as there is an anticipated decline in certain professions, while an increase in cooks and food preparation workers is expected by 7 percent over a decade.
It is imperative to focus on sustainable development goals to achieve zero hunger and address the coming food crisis, as the world population is rising exponentially and stressing the environment and food demands. Therefore, while specific numbers for ZCoB in 2020 are not provided, the information underscores the importance of addressing the global hunger crisis and supporting employment within the food industry.
