Introduction
In this investigation we investigate about the Forest in Paraguay but we took specially 2: The Great South American Chaco Forest and the Atlantic forest that is one of the biggest in south America, the Interior Atlantic Forest is one of the most biologically diverse yet threatened ecosystems in the world and have 300 acres, but now a little of that 300 acres is not plant because In recent years, Paraguay has experienced the most rapid rate of deforestation in all of South America. Much of this has come at the expense of the country’s lush Interior Atlantic Forest region, where more than 90% of the population lives.

General Objectives
* To understand the importance of reforestation.
Specific Objectives
* To know more about forest in Paraguay.
* To think more until you do something that is harmful for forest. * to create awareness in people.

Problem
One of the main problems our country is facing, is deforestation rate in the last 10 years, the cause of this problem that the human being is not consent of what he is doing and of the consequences he produce. There are more than 16000 ha. deforestated areas in Paraguay and the people continue cutting trees for economical purposes.

Hypothesis
The solution for this problem is to stop deforestation, but the people don’t care about and continue doing it. We believe that if our generation knows about it and do something about it; like planting new trees wherever it is possible and help preserving the green areas, and we will create all together, a better place to live.

The Great South American Chaco
Historically the Chaco has been divided in three main parts: the Chaco Austral or Southern Chaco, south of the Bermejo River and inside Argentinian territory, blending into the Pampa region in its southernmost end; the Chaco Central or Central Chaco between the Bermejo and the Pilcomayo River to the north, also now in Argentinian territory; and the Chaco Boreal or Northern Chaco, north of the Pilcomayo up to the Brazilian Pantanal, inside Paraguayan territory and sharing some area with Bolivia. Nowadays locals sometimes divide it simply in regard to the political borders, giving rise to the terms Argentinian Chaco, Paraguayan Chaco and Bolivian Chaco. (Inside Paraguay, people sometimes use the expression Central Chaco to the area roughly in the middle of the Chaco Boreal, where mennonite colonies are established.) The Chaco Boreal may be divided furthermore in two: closer to the mountains in the west, the Alto Chaco, or Upper Chaco, sometimes known as Chaco Seco or Dry Chaco, is very dry and sparsely vegetated, continuing eastward where less arid conditions combined with favorable soil characteristics permit a seasonally dry higher growth thorn tree forest, and further east again where still higher rainfall combined with improperly drained lowland soils lead to a somewhat swampy plain called the Bajo Chaco or Lower Chaco, sometimes known as Chaco Húmedo or Humid Chaco, with a more open savanna vegetation consisting of palm trees, quebracho trees and tropical high grass areas with a wealth of insects. The landscape is mostly flat and slopes at a 0.004 degree gradient to the east. This area is also one of the distinctphysiographic provinces of the Parana-Paraguay Plain division. The areas more hospitable to development are along the Paraguay, Bermejo and Pilcomayo Rivers. It is a great source of timber and tannin, which is derived from the native quebracho tree. Special tannin factories have been constructed there. The wood of the palo santo from the Central Chaco is the source of oil of guaiac (a fragrance for soap). Paraguay also cultivated mate in the lower part of Chaco. The Chaco offers high soil fertility and a topography that is favorable for agricultural development, but in combination with aspects that are challenging for farming: a semi-arid to semi-humid climate (600–1300 mm annual rainfall) with a six-month dry season and sufficient...
