Factors that Affect the Human Population The human population is increasing rapidly due to improvements in agriculture, living conditions and medicines like antibiotics/immunisations. Increases in population size leads to an increase in deforestation, pollution and the loss of habitats which all make higher demands on the earth’s resources. Wildlife and their habitats are harmed because of the greenhouse gases released such as carbon dioxide, methane, cfc’s and nitrogen oxide. All these gases contribute to the greenhouse effect, acid rain and pollution in the air, soil and water. As the air is polluted through the burning of…show more content…
The lack of snow makes it hard for reindeer to feed on the lichen as the plants are covered in sharp ice, which then cuts their soft muzzles. Plants are covered in the sharp ice instead of soft snow as the area is being warmed up due to more carbon dioxide in the air. Deforestation is the permanent destruction of indigenous forests/woodlands. Between 1990 and 1995, there was 1.2 million acres of forest destroyed for the uses of building homes, commercial logging and farming. The destruction of the Brazilian Atlantic forest is devastating as there is only about 7% left due to deforestation. Most of the forest was destroyed by farmers so they could plant and grow sugar, coffee and other crops and also for growing cities like Sao Paulo and Rio de Janeiro. Five hundred years ago, the Atlantic Forest of Brazil covered approximately 330 million acres but today more than 92% of this forest has been cleared. With this rapid shrinking rate, animals are forced to change their patterns of living, as well as their patterns of hunting enabling them to survive. Many animals are not able to adapt to these rapid changes and they are dying off at an incredible rate. Approximately one hundred species per day are going extinct due to deforestation. These animals need trees/vegetation to survive. Despite its diminished state, the Atlantic Forest harbors around 2,200 species of
