None that he knows of. He was raised by his uncle and grew up with his cousin, and it is unknown if he has any siblings.

Earthshine is even more faint because the moon's "albedo" (a specific kind of reflectivity) is less than Earth's. Even though this dim light is only a reflection it can still illuminate some features of the moon. Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon).
The correct answer is A. Increased use of pesticide.
The name 'green revolution' is very misleading, because it makes you believe that is something positive about the nature. In fact, it is something that made a lot of harm to the environment with pollution and increased erosion caused by the usage of chemical fertilizers and pesticides and herbicides, caused problems in the societies because a lot of crops needed for people to feed themselves where destroyed so that other plants can be produced.
A cliff collapse could affect the environment by exposing new rock (previously covered by the cliff) to the elements, which could result in runoff of a different nature when it rains. Additionally, the cliff would collapse upon whatever life/features existed at the base of the cliff. One of the most drastic effects could be the shaking of the earth. Cliff failures can result in earthquakes or, if the cliff collapses into a large body of water, massive tsunamis which radically impact coastal environments.
