Final answer:
Conservation tillage is a sustainable agricultural practice that increases the carrying capacity for humans by improving soil quality and productivity, which supports a larger population.
Step-by-step explanation:
The statement that conservation tillage is an approach of increasing carrying capacity for humans is true. Conservation tillage is a sustainable agricultural practice that reduces soil erosion and improves soil quality, which can lead to an increase in soil fertility and productivity. Since carrying capacity refers to the number of individuals that an environment can sustain without degrading, practices like conservation tillage that enhance food production directly contribute to the ability to sustain a larger population. In contrast to conventional agriculture which often involves intensive tilling, conservation tillage, including no-till farming, is seen as a way to enhance the sustainability of agriculture by improving soil health and reducing the emission of greenhouse gases.
