HUMAN IMPACT ON THE NATURAL ENVIRONMENT: humans use the
natural environment on a resource, factors influence: -population
-technology -energy -consumption. THE MAN THREAT TO THE
ENVIRONMENTS ARE: -air pollution -water pollution -endanged species -
erosion and desetification. AIR POLLUTION is caused by the emission of
gases into the air as a result of human activity, is bad for the health.
SMOG: formed by chemical reaction between sunlight and nitrogen oxides
at ground level. ACID RAIN: ocurss when the nitrogen oxides and carbon
dioxide mix with rain to produce acids. OZONE: is a gas found in the
atmosphere. WATER SUPPLY: 97 saler water 3 fres water 2 ice 1
undergorund lakes rivers and potable. Fresh water is a renewable source
but it is scarce, distribution isn´t even. DEFORESTATION: is the loss of the
area convered by forests as a result of human activity. 5factors forests are
important. -forest absorb co2. -they are the habitat of species, plants and
animals -they cover soil -they lower temperaturas of the eart´s -the trees
play a role in the water cycle. SOIL DEGRADATION: is the loss of soil fertility
due to the following factors. Contamination, erosion, deforestation, loss of nutrients.
