ENVIRONMENTAL PROBLEMS
The incineration and burning of forest plants to clear land releases large amounts of CO2, which contributes to global warming.
Recent calculations suggest that carbon dioxide emissions from deforestation and forest degradation contribute about 12% of total anthropogenic carbon dioxide emissions with a range from 6 to 17%.
Scientists state that, Tropical deforestation releases 1.5 billion tons of carbon each year into the atmosphere.
Trees no longer evaporate away this water, resulting in a much drier climate.
Deforestation reduces the content of water in the soil and groundwater as well as atmospheric moisture.
The presence or absence of trees can change the quantity of water on the surface, in the soil or groundwater, or in the atmosphere.
Tropical rainforests produce about 30% of our planet's fresh water.
HYDROLOGICAL PROBLEMS
REDUCED BIODIVERSITY
About 80% of the world's known biodiversity could be
found in tropical rainforests.
Removal or destruction of significant areas of forest
cover has resulted in a degraded environment with
reduced biodiversity.
It has been estimated that we are losing 137 plant,
animal and insect species every single day due to
rainforest deforestation, which equates to 50,000
species a year.

SOLUTIONS TO DEFORESTATION
Reforestation
Forest Plantations
Wildlife Sanctuaries
REFORESTATION
Improves the quality of human life by soaking
up pollution and dust from the air, rebuild
natural habitats and ecosystems.
The amount of woodland has increased in 22 of the world's
50 most forested nations.
Most reforestation involves the planting of different feedlots
of seedlings taken from the area often of multiple species.
FOREST PLANTATIONS
Designed to meet the world’s demand for wood.
Can be managed in ways to enhance biodiversity protection functions.
Important providers of ecosystem services such as maintaining nutrient capital.
WILDLIFE SANCTUARIES
Provides protection for species from hunting, predation or competition.
They provide habitat for wildlife (endangered species) and also cultural enrichment for patrons educational opportunities, recreation, and preserve open space for future generations.
Trees would be able to provide animals like birds with water and abundance of food resources.
