Based on the text, explain why in the year 1,600, extinction of flora and fauna is only 50 species per century, while at present extinction is 1 species per hour. Environmental Principle No. 6Finiteness of ResourcesThe finiteness of the Earth's resources can be seen in the following ways:1. Limits to the Earth's carrying capacity. The amount of life the Earth can supportFor example a hectare of land can only support about 10 deer, 100 snakes, andthousand of mice. Over population of one species can lead to an imbalance. An54 environmental issue brought about by exceeding the threshold level of anecosystem is extinction. There is natural extinction but man-made factors such asdestruction of habitat is systematically wiping out species of flora and fauna.In 11,000 to 18,000 Before Christ on Earth (BCE), three species gets extinct percentury. By 1,600, 50 species per century. At present, 1 species per hour.

Solution: The earth has certain limits in terms of the amount of life it can support. This life…

32.) In the United States most of the fuel used comes from a classification called fossil fuels. What does fossil fuel refer to? a. fuel that formed from ancient plant and animal life, representations of which are sometimes found as fossil imprints b. a technique known as fossilization that must be used in order to obtain energy from these fuels embedded fossil remains in the fuel itself

Consider a river that spreads out in a delta region on its way to the sea. Construct a problem in which you calculate the average speed at which water moves in the delta region, based on the speed at which it was moving up river. Among the things to consider are the size and flow rate of the river before it spreads out and its size once it has spread out. You can construct the problem for the river spreading out into one large river or into multiple smaller rivers.

Before an earthquake hits, the University of Ruritania (UR) had rooms enough for 5000students, which it rented at $300 per month per student. At that price, 500 students whowanted rooms on campus had to be turned away.a. The earthquake damages 1000 rooms, and it will take one month to make repairs. Graphwhat the earthquake does to short-run supply and demand for on-campus rooms.b. After the repairs are made (taking the total rooms back to 5000), UR decides to constructadditional housing for 1050 students (which will raise the total to 6050). It plans to lowerthe price for rooms so that all rooms are occupied. About how much will rent be if theelasticity of demand is -4? How about -2? How about -.2? In which case would the newhousing increase university rental revenues the most?c. How is your calculation in b) affected if rent is set in Ruritanian clochemarks($1=2.75cm) instead?
The newly appointed Government of a small island, depend on the import of fossil fuels to produce electricity, has the desire toinvest in one or two renewable energy technologies. The advantage of the island is the number of different renewable energypotentials. The cost of electricity on the island is $0.39 kWh.1) Using solar radiation photovoltaic technologies, it was estimated that 500 rooftops, with a total surface area of 456 000 m2 will be available to install the photovoltaic panels. Assume that the solar panels actually cover 90% of the available surface area. Given, the size of a standard photovoltaic cell is 156 mm by 156 mm and for a silicon photovoltaic cell, each PV cellproduces a current of 2.5 A at a voltage of 0.5 V. The average daily irradiance for the island is 185 W/m2. Assume the initial capacity expenditure evaluated on a yearly basis of the photovoltaic system, that covers, 90% of the available surface area is US$600 000 and the annual operating cost is US $5…

1.) Natural gas is the most abundant fossil fuel in the world. a. True b. False
The “biological capacity” is the ability of the natural world to replenish its renewable resources and absorb the resulting waste products and pollution. Exceeding the biological capacity creates an “ecological deficit.” Discuss the potential future implications for the earth resulting from the fact that we are currently exceeding the earth’s biological capacity by about 50 percent
