DEFORESTATION

• Habitat for millions of plants, animal species, and humans

• Source of food and raw materials

• Source of livelihood

• Source of medicine

• “Lungs of the Earth” – trees absorb CO2 and release 02

• Protector against global warming

• Influence global climate

IMPORTANCE OF FOREST

Deforestation

clearing of a vast tract of forestland by cutting down trees

• conversion into agricultural, commercial, or residential land

• rampant cutting down of trees for various wood products

• illegal logging

• slash and burn agriculture

• forest fires and calamities

• mining

• rapid population growth

Causes of deforestation

Reforestation

process of implementing programs, projects, and regulations aimed at renewing and regenerating forest areas

• FLOODING

• DROUGHT

• SOIL EROSION AND LANDSLIDE

• EFFECT ON CLIMATE

• LOSS OF LIVELIHOOD

• HEALTH ISSUES

Effects of deforestation

FLOODING

due to absence of trees in forests that are supposed to absorb rainwater

DROUGHT

desertification, a process where the soil loses its ability to support any living thing; absence of roots of trees causes shortage of groundwater

SOIL EROSION AND LANDSLIDE

rainwater washes away soil nutrients; occurs because there are no roots of trees that could hold the soil

EFFECT ON CLIMATE

less humidity because there are less leaves that release moisture; rainfall, precipitation, and wind patterns are affected

LOSS OF LIVELIHOOD

due to shortage of resources coming from the forests

HEALTH ISSUES

due to water pollution and lessened availability of medicinal plants found in forests
