The vertical axis is labeled millions and ranges from 0 to 900 in increments of 100. The horizontal axis is labeled year and lists dates from 1700 to 2000 in 100-year increments. The line for population starts at 90 million for 1700 and with a slow growth rate reaches to 120 million by 1900. The line then rises with a high growth rate and reaches beyond 600 million by 2000. The line for steel consumption starts from 0 in 1860 and reaches 20 million by 1900. The line then rises with a high growth rate to reach beyond 800 million by 2000. The values used in the description are approximate.

With such huge increases in population, why has there not been a direct and equivalent increase in urban development (i.e., why is it such a small proportion of habitable land use)?(1 point)
Responses
Habitable land is already being used for livestock and crops.

In three to five sentences, describe two impacts of obtaining nonrenewable resources and how these have been affected by increasing population.(4 points)
Obtaining nonrenewable resources, such as oil, coal, and natural gas, has serious environmental impacts. Environmental damage includes habitat destruction, water and air pollution, soil degradation, and climate change. Moreover, increasing population demands more nonrenewable resources that will deplete these finite resources more quickly. This also leads to more environmental degradation. The increase in population results in greater demand for nonrenewable resources, which, in turn, leads to more environmental and social impacts.
In order to expand agriculture and stimulate a sagging economy, the Brazilian government eased environmental laws which allowed large tracts of rainforest to be cut down or burned. In three to five sentences, construct a potential chain of consequences for what can happen as a result of this kind of deforestation. The chain does not have to be linear (i.e., five steps in a row), but can have several branches, one for each different potential consequence. Your chain should include at least four steps, including the original event.(4 points)
The Brazilian government's ease of environmental laws led to deforestation of large swathes of rainforest. As a consequence, the loss of trees led to soil degradation, increased carbon dioxide concentrations, and disrupted ecosystems. Furthermore, this could result in a poorer agricultural yield, as the rainforest soil is very fragile, and the absence of the dense tree cover can lead to soil erosion via exposure to higher rainfall intensity that normally would be absorbed by the trees. These consequences would increase climate change.
In three to five sentences, describe how a person can reduce consumption of natural resources when drinking water. Assume that there is no change in the amount of water consumed and that the change is only in the way water is produced.(4 points)
A person can reduce their consumption of natural resources when drinking water by using a water filter. This eliminates the need for bottled water and decreases the use of plastic packaging. Additionally, using a reusable water container can further reduce waste and prevent the use of disposable plastic water bottles. Lastly, individuals can decrease resource consumption by being mindful of water usage and making small changes, such as turning off the tap when brushing teeth or taking shorter showers.

A city planner is designing a new apartment complex. The complex will have several apartment buildings as well as a paved parking area for residents.
In one to two sentences, describe two ways the planner can help minimize the human impact of the apartment complex on the environment.
(2 points)
The city planner can minimize the human impact of the apartment complex on the environment by incorporating green spaces, such as planting trees and gardens, to increase oxygen and biodiversity in the area. Additionally, the planner can use materials that have a lower environmental impact, such as sustainable wood, energy-efficient windows and appliances, and recycled or eco-friendly building materials.
