Many cities are reluctant to regulate the trucking industry, which is seen as a sector that supports an area's economy. However, trucks are major contributors to air pollution in large cities and congested areas. Based on what you experienced in the decision scenarios, think about how you would weigh the pros and cons of reducing air pollution from commercial vehicles, such as tractor-trailer trucks or box trucks. In a paragraph or two, provide a recommendation for a large city, such as New York City, on how to reduce air pollution from trucks without negatively impacting the economics of transporting goods by either large or small commercial trucks. In your answer (approximately 500 words), make sure to use the events and outcome of the example you just read to support your reasoning.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
