Answer:
- British Impressment of American Sailors.
- British restriction of U.S. trade.
Explanation:
Thomas Jefferson tried to follow the ideology of George Washington in that the U.S. must remain neutral in issues relating to other countries especially those of Europe. The British however, were engaged in war with the French and so engaged in policies that angered the United States.
The first was Impressment. The British needed sailors in their fight against the French and so would regularly seize American Sailors and add them to the Royal Navy's ranks to bolster their numbers. This was tantamount to kidnap and infuriated the American public.
The other was the restriction of trade with Europe (France in particular) by the British. The British demanded by American ships go to Britain first if they were going to Europe and captured American ships sailing there so as to deny Napoleon any American supplies. This had disastrous effects on the American economy as many suffered from being unable to export freely.
Answer:
The steppe crosses the Russian plain, south of the taiga, penetrating deep into Siberia. It comprises three main types, which run in roughly parallel bands from east to west: forest steppe in the north, through steppe, to semi -desert steppe in the south. Within these belts, zones of temporary inundation on floodplains or in zones of internal drainage provide valuable hay land. The steppe was increasingly ploughed for crops during the twentieth century; initially crops were rotated with naturally regenerated grassland, but from mid-century cultivation was increasingly intensive. During the collective period, the emphasis was on industrial stock rearing, with housed cattle and high inputs; since decollectivization, intensive enterprises are closing for economic reasons, and systems have yet to stabilize. If ploughed land is left undisturbed it will return naturally to steppe vegetation in six to fifteen years. Hay is very important for winter feed, and much is made from seasonally flooded meadows. Many marginal, semi-arid areas of the steppe have been put under crops, but are not economically viable; much of the cereals so produced are fed to livestock, but grain yields are very low and yield no more livestock products than would natural grassland, but at far higher cost. Marginal cropland should return to grass.
