because it has increasing opportunity costs
If the opportunity cost is constant, the PPF is a straight line; when the opp. cost of a good rises when it is produced more, then concave.
A PPF is the locus of points such that all the economy's resources are used to its fullest potential. A PPF is concave to the origin because of the increasing opportunity cost to produce an additional unit of x (on the horizontal axes). A point inside the PPF is attainable because (1) there may be no full employment or (2) inspite of full employment they are used to less potential. On the contrary a point outside the PPF is not attainable because the PPF itself is the locus of the maximum attainable output given resources, the PPF may however expand due to increase in resources or their efficiency.
A Production Possibility Frontier (PPF) is a curved bowed out from the origin. It is mostly 2 dimensional and involving 2 goods or services.
The PPC / PPF is concave to the origin because not all resources are perfectly suited to the production of both goods. This leads to increasing opportunity costs caused by diminishing returns. So as more and more resources are switched from the production of one good to the production of another good, returns diminish. This is the law of diminishing returns. This law is identified by the PPC being concave. As an example, consider production of root beers to mountain bikes. When most workers are making bikes, the few remaining in brewing buisness are the best brewers. If more bikes are to be produced, then the most skilled beer workers have to be shifted to bike manufacturing, thereby affecting the amount to beer significantly. A concave PPF is generally applicable in cases where the production requires specialization and varied raw products (eg. guns and butter as given on wikipedia.) In cases of similar goods, it is generally a straight line, eg. production of cakes and pastries.
why PPF in economics is negatively sloped
If the opportunity cost is constant, the PPF is a straight line; when the opp. cost of a good rises when it is produced more, then concave.
The PPF is bowed outwards (concave to the origin) as tradeoffs between the production of any two goods are constant.

A production possibility curve is concave because of the law of diminishing returns. As more resources are allocated to one good over the other, the opportunity cost increases, which leads to decreasing marginal rates of substitution. This results in a concave curve that shows the trade-off between producing different goods.
When there are diminishing marginal returns to factors of production, the PPF is "bowed out" from the origin.
A Production Possibility Frontier (PPF) is a curved bowed out from the origin. It is mostly 2 dimensional and involving 2 goods or services.
The word concave is derived from the Latin word concavus, from cavus, meaning cave.

why PPF in economics is negatively sloped
PPF - company - was created in 1991.
The Law of Increasing Opportunity Cost that is shown in a Production Possibilities Curve is concave to the origin. This is because it shows the maximum gain of two products used in production.
