Agriculture has had a variable impact on the Earth’s carbon cycle because ____
A
forests are turned into farmland.
B
the burning of wild fires add CO2 to the atmosphere.
C
farm animals have a very high carbon footprint.
D
forest are being removed because people need lumber and wood for contruction purposes.
Explanation: 

Detailed explanation-1: -Besides its contribution to global warming, farming has other detrimental effects on the environment. Agriculture is often the reason for deforestation and a change in land use, from natural ecosystems that take up and store carbon dioxide (CO2) from the atmosphere, to farmland.

Detailed explanation-2: -Climate change can affect agriculture in a variety of ways. Beyond a certain range of temperatures, warming tends to reduce yields because crops speed through their develop-ment, producing less grain in the process. And higher tem-peratures also interfere with the ability of plants to get and use moisture.

Detailed explanation-3: -Rising levels of atmospheric carbon dioxide reduce the concentrations of protein and essential minerals in most plant species, including wheat, soybeans, and rice. This direct effect of rising CO2 on the nutritional value of crops represents a potential threat to human health.

Detailed explanation-4: -Forests play a major role in sustainable agricultural development through a host of channels, including the water cycle, soil conservation, carbon sequestration, natural pest control, influencing local climates and providing habitat protection for pollinators and other species.
