A. increased water scarcity B. overfishing C. decreased soil salinity D. deforestation
Overfishing, decreased soil salinity and deforestation are concerns about agricultural production and its effect but the increased water scarcity is not.
Overfishing is considering a fish species from the water and because of that population of fish is lack which is not good.
Soil salinity can stop the plant from growing and also the quality of water.

Answer: 
Explanation:
The Tropic of Cancer is one of the parallels (imaginary line around the Earth parallel to the equator) located in the northern hemisphere (currently its latitude is
).
It is called "Cancer" because a long time ago, when the summer solstice occurred in the northern hemisphere (on June 20th or 21st), the Sun was in the constellation Cancer (the crab).
Now, if we were just in the North Pole, Polaris would by exactly over our heads (
over the horizon), but as we go south and find the Tropic of Cancer parallel, Polaris altitude will be approximately at an angle of
over the horizon.
Hence, the altitude of Polaris measured by an observer at the Tropic of Cancer is
.
I think the answer is B.
hope this helps x
