In cosmology and astronomy the phenomena of stars, nova, supernova, quasars and gamma-ray bursts are the universe's highest-output energy transformations of matter. All stellar phenomena (including solar activity) are driven by various kinds of energy transformations. Energy in such transformations is either from gravitational collapse of matter (usually molecular hydrogen) into various classes of astronomical objects (stars, black holes, etc.), or from nuclear fusion (of lighter elements, primarily hydrogen). The nuclear fusion of hydrogen in the Sun also releases another store of potential energy which was created at the time of the Big Bang. At that time, according to theory, space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements. This meant that hydrogen represents a store of potential energy that can be released by fusion. Such a fusion process is triggered by heat and pressure generated from gravitational collapse of hydrogen clouds when they produce stars, and some of the fusion energy is then transformed into sunlight.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What releases another store of potential energy which was created at the time of the Big Bang?
Ah, so.. nuclear fusion of hydrogen in the Sun

The first set of subsidiary forts were planned by the Portuguese at Montevideo in 1701 to establish a front line base to stop frequent insurrections by the Spaniards emanating from Buenos Aires. These fortifications were planned within the River Plate estuary at Colonia del Sacramento. However, this plan came to fruition only in November 1723, when Captain Manuel Henriques de Noronha reached the shores of Montevideo with soldiers, guns and colonists on his warship Nossa Senhora de Oliveara. They built a small square fortification. However, under siege from forces from Buenos Aires, the Portuguese withdrew from Montevideo Bay in January 1724, after signing an agreement with the Spaniards.

Ah, so.. 1701

Due to many centuries of intensive settlement, most of the area is shaped by human influence. The original natural vegetation of Thuringia is forest with beech as its predominant species, as can still be found in the Hainich mountains today. In the uplands, a mixture of beech and spruce would be natural. However, most of the plains have been cleared and are in intensive agricultural use while most of the forests are planted with spruce and pine. Since 1990, Thuringia's forests have been managed aiming for a more natural and tough vegetation more resilient to climate change as well as diseases and vermin. In comparison to the forest, agriculture is still quite conventional and dominated by large structures and monocultures. Problems here are caused especially by increasingly prolonged dry periods during the summer months.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where do most landscape problems come from?
Ah, so..
increasingly prolonged dry periods during the summer months
