Author’s vision of a more sustainable world, which could be attained by 2065.
Answer to Problem 1CR
The author imagines that by 2065 the loss of species, land degradation, water pollution, air pollution, population growth, and use of non-renewable energy resources would have considerably reduced and people would have started depending on more renewable energy resources and would have begun following more sustainable lifestyles.
Explanation of Solution
The author noticed that by 2018 a small but increasing percentage of people had started adopting lifestyles that are more environmentally sustainable. The author imagines that if the pace toward such an environment-friendly life continues, then, by 2065, species loss and land degradation would have reduced, the oceans, atmosphere, rivers, and lakes would be much cleaner, and about 80 percent of the solid wastes would be recycled or reused, and the wastage of energy could be reduced to half.
The considerable atmospheric warming and the subsequent climatic fluctuation that was predicted by several scientists in 1990s would have happened by 2050. Nevertheless, the risk of further climatic fluctuations and water and air pollution would have started to reduce due to highly declined energy wastage and the slow shift in human use of energy resources from coal and oil to eco-friendly and pollution-free energy from wind, Sun, moving water, and other non-conventional resources.
The author expects the farmers producing most of the global food to have shifted to more sustainable agricultural practices that aided in water conservation and in the protection and renewal of the fertile topsoil. Moreover, the human population would have increased at about 8 billion by 2050 and then would have started a gradual decline, decreasing human pressure on the life-support systems of the Earth. In 2065, the author expects the Earth to be a more sustainable planet.

As a result, some of this region has recently been uplifted and exhibits characteristics of an emergent coastline. On the other hand, because of the general rise in sea level over the past several thousand years, other areas exhibit features associated with submergent coastlines. Refer to this topographic map to complete the following. 1. What type of shoreline feature is Drakes Estero (located near the center of the map)? 2. Point Reyes, located in the bottom-left corner of the map, is a headland undergoing severe wave erosion. What type of feature is Chimney Rock, located off the shore of Point Reyes? 3. Several depositional features near Drakes Estero are related to the movement of sediment by longshore currents. What type of…arrow_forward
- Activity 12.3: Wave Refraction Pgs 202-203Figure 12.2 is a map view of a headland along a coastline. The water depths are shown by blue contour lines. As you complete the following questions, assume that waves with a wavelength of 60 feet are approaching the shoreline from the bottom left of the figure. 1. At approximately what water depth-10, 20, 30, or 40 feet-will the approaching waves begin to touch bottom and slow down? (Hint: Recall that this occurs when the water depth is one-half the wavelength.) 2. Using the wave shown in Figure 12.2 as a starting point, sketch a series of lines to illustrate the wave refraction that will occur as the wave approaches the shore by following these steps:Step 1: Mark the position on the 30-foot contour line where the wave front will first touch bottom.Step 2: Knowing that the section of the wave that touches bottom will slow down first, sketch the shape of the wave front when it reaches the 20-foot contour line.Step 3: Using the same…arrow_forwardCan trace and tell me how they did itarrow_forwardCan someone show me how they would trace thisarrow_forward
