The supply of Earth’s fresh water is fixed and is being depleted at a rapid rate. Which of the following best describes the effects of a limited freshwater supply on human populations? A. Disease transmission will decrease as access to water decreases, leading to improved public health.
B. Conservation measures will increase per capita water consumption, leading to an improved global economy.
C. Desalinization facilities will be used to process water stored in glaciers and snow packs, leading to new sources of drinking water.
D. World food production will decrease, leading to increased famine.

The depletion in the rate of fresh water supply will have a negative impact on earth, with a possible result being the the reduction in food production, which might lead to increased famine due to insufficient water supply necessary for plant and animal growth.

The consequences of reduction in fresh water supply would most likely be dire and negative due to the huge usefulness of water supply in plant and animal sustainability. Disease transmission will most likely increase rather than decrease due to low moisture content. Conservation measures are usually practiced to increase sufficiency, when supply is very limited, conservation measures will only be a temporal measure to limit the effect of a phenomenon.

Therefore, limited water supply will negatively affect food production and result in famine.

Answer from: jordynnmarelich1194

The correct answer is D) World food production will decrease, leading to increased famine.

Explanation:

Global demand for freshwater in the next 3 decades is estimated to grow to as much as 55% when juxtaposed with the figures for two decades ago.

This demand can be termed derived given that it will be driven primarily by a surge in demand for food crops which exert a great demand on the earth's hydrological cycle.

A hydrological cycle refers to the systems through which water travels from the beneath the earth to above the earth and upon the earth, back and forth and all over.

The answer is (d) 7/2======we have $f(x) = \begin{cases} x & \text{ for } x \le 0 \\ x + 1 & \text{ for } x \ \textgreater \ 0 \end{cases}$ we also have an integral $\displaystyle\int_{-2}^1 x\, f(x)\; dx$ notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum: $\displaystyle\int_{-2}^1 x\, f(x)\; dx = \displaystyle\int_{-2}^0 x\, f(x)\; dx + \displaystyle\int_{0}^1 x\, f(x)\; dx$ notice that for the piecewise function f, the function has the equationf(x) = x when x ≤ 0. so for the integral $\int_{-2}^0 x\, f(x)\; dx$ , f(x) = x so it changes into $\begin{aligned} \int_{-2}^0 x\, f(x)\; dx & = \int_{-2}^0 x \cdot x\; dx \\ & = \int_{-2}^0 x^2\; dx \\ & = \left[\frac{x^3}{3}\right]_{-2}^0 & & \text{\footnotesize antidifferentiate} \\ & = 0 - \frac{(-2)^3}{3} \\ & = \frac{8}{3} \end{aligned}$ for the piecewise function f, the function has the equationf(x) = x+1 when x > 0. for the integral $\int_{0}^1 x\, f(x)\; dx$ , we have $\begin{aligned} \int_{0}^1 x\, f(x)\; dx & = \int_{0}^1 x(x+1)\; dx \\ & = \int_{0}^1 (x^2+x)\; dx \\ & = \left[ \frac{x^3}{3} + \frac{x^2}{2}\right]_0^1 \\ & = \frac{1}{3} + \frac{1}{2} - 0 = \frac{5}{6} \end{aligned}$ therefore, back to our splitted integral: $\begin{aligned} \displaystyle\int_{-2}^1 x\, f(x)\; dx & = \displaystyle\int_{-2}^0 x\, f(x)\; dx + \displaystyle\int_{0}^1 x\, f(x)\; dx \\ & = \frac{8}{3} + \frac{5}{6} \\ & = \frac{7}{2} \end{aligned}$
