Impact Deforestation Bird communication
The earth's forests serve as a habitat for fifty percent of the world's species. They also are the most threatened systems on land according to the article Forces behind forest loss by Rhett. A. Butler. They are threatened by humans who make use of the forests' lands; the forest is lost permanently or is lost on a long term. This reducing of the forest for land use is termed deforestation. All around the world deforestation is causing a massive loss of species. If there is no conservation many species that has the use of providing the earth with biodiversity will soon become extinct. In this assignment the main focus is on the impact of deforestation on bird communication.
Birds have different ways of communicating with each other, such as vocal communicating and the posture of the body of the bird. Examples of vocal communication are making alarm calls when they detect danger, and they making calls to partners when they are in mating season. The main reasons for bird communication are to attract mates, to get rid of enemies, and for protection of their territory.
Deforestation entails the loss of trees for the use of the land by humans. One natural cause of deforestation is fire. Other causes of deforestation are by humans for agricultural systems and cattle-raising, dams and megaprojects, logging, mining, getting oil and gas, improving infrastructure, purpose or accidental lighting of fire, and the building of plantations. Poor farmers are allowed to use forest lands by governments; this allows a significant amount of deforestation.
Humans rely on the rainforests for erosion prevention, flood control, water treatment, fisheries protection, pollination, renewable resources like timber, medicinal plants, nuts and fruit, and game; mainly for a constant acceptable global climate and biodiversity.
The number of birds reduces with increasing population of humans. A numerous amount of people leads to more houses needed, thus more lands gotten from forests which is destroyed therefore the habitats of the birds are destroyed. If they are adaptable only to those environmental conditions, they will die elsewhere.
There are also the migratory birds, who migrate annually. These birds collide into buildings such as the communication towers.
The loss of diversity which is caused by deforestation appears to be accelerating.
From the article, 'Study Warns Climate Change and Deforestation will Lead to Declines in Global Bird Diversity'by Kim Mc Donald, it is written "We found in our study that under certain assumptions by the year 2100, 950 to 1,800 bird species may be imperiled or even driven to extinction by climate change and habitat destruction," says Walter Jetz, an assistant professor of biological sciences at UCSD and the lead author of the study. "Most of these species are currently not recognized as imperiled."
The species of birds are declining due to deforestation which has no easy solution. One way to start is to decrease the number of products made by use of the forests. Recycling programs should have a lot of emphasis. There should be reforestation projects to reverse the consequences of deforestation such as the extinction of various bird species.
