Deforestation. Answer: Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food. Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food. Medicinal plants are supplied through collection from wild populations and cultivation. A 2015 study from researchers in Argentina that was published in the journal Agriculture, Ecosystems & Environment found that small mammals were more abundant around organic farms than conventional farms. Human health is directly linked to food production and because biodiversity affects food availability (both wild and cultivated), it also affects health. Disease burden on humans is increased, particularly on those of a lower socioeconomic background and vulnerable groups. Marine biodiversity is affected by ocean acidification related to levels of carbon in the atmosphere. of the same food can differ dramatically, affecting micronutrient availability in the diet. We need to learn from these past scientific and societal successes. and Loss of soil biodiversity makes soil less resilient and undermines its ability to support wild and cultivated food plants. Humans impact the physical environment in many ways: overpopulation pollution burning fossil fuels and deforestation.
