b. crop rotation
c. thinning
d. shelterwood harvest

A. Slash and burn

Explanation:

The slash and burn method is a very harmful method for the soil, as well as for the whole environment. This method is consisted in total removal and burning of the vegetation in certain area in order to free up space for farmlands. The slash and burn method is mostly used in forested areas, the majority of which are tropical rainforests. The soil in this areas is relatively good, but its top part is very loose, so once the natural protection of the vegetation is removed, it is heavily affected by erosion. This leads to a situation where the soil can only be used fro few years before it becomes almost unusable, so the people continue to slash and burn other areas, living behind barren land with very poor soil.

separation of powers, therefore, refers to the division of government responsibilities into distinct branches to limit any one branch from exercising the core functions of another.   the intent is to prevent the concentration of power and provide for checks and balances.  

the traditional characterizations of the powers of the branches of american government are:

* the legislative branch is responsible for enacting the laws of the state and appropriating the money necessary to operate the government.

* the executive branch is responsible for implementing and administering the public policy enacted and funded by the legislative branch.

* the judicial branch is responsible for interpreting the constitution and laws and applying their interpretations to controversies brought before it.

forty state constitutions specify that government be divided into three branches:   legislative, executive and judicial.   california illustrates this approach; "the powers of state government are legislative, executive, and judicial.   persons charged with the exercise of one power may not exercise either of the others except as permitted by this constitution."

while separation of powers is key to the workings of american government, no democratic system exists with an absolute separation of powers or an absolute lack of separation of powers. governmental powers and responsibilities intentionally overlap; they are too complex and interrelated to be neatly compartmentalized. as a result, there is an inherent measure of competition and conflict
