TREES COMBAT CLIMATE CHANGE
Excess carbon dioxide (CO2) is building up in our atmosphere, contributing to climate change. Trees absorb CO2, removing and storing the carbon while releasing oxygen back into the air. In one year, an acre of mature trees absorbs the same amount of CO2 produced when you drive your car 26,000 miles.
02.
TREES CLEAN THE AIR
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.
03.
TREES PROVIDE OXYGEN
In one year an acre of mature trees can provide enough oxygen for 18 people.
04.
TREES COOL THE STREETS AND THE CITY
Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.
05.
TREES CONSERVE ENERGY
Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50 percent. By reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.
06.
TREES SAVE WATER
Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.
07.
TREES HELP PREVENT WATER POLLUTION
Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.
08.
TREES HELP PREVENT SOIL EROSION
On hillsides or stream slopes, trees slow runoff and hold soil in place.
09.
TREES SHIELD CHILDREN FROM ULTRA-VIOLET RAYS
Skin cancer is the most common form of cancer in the United States. Trees reduce UV-B exposure by about 50 percent, thus providing protection to children on school campuses and playgrounds - where children spend hours outdoors.
10.
TREES PROVIDE FOOD
An apple tree can yield up to 15-20 bushels of fruit per year and can be planted on the tiniest urban lot. Aside from fruit for humans, trees provide food for birds and wildlife.
Answer:
Importance of Trees and Forests
We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change. Yet, despite our dependence on forests, we are still allowing them to disappear. Our failure to take care of our forests is threatening the very existence of man and wildlife. Legal and illegal commercial logging had taken its toll on our environment.
1. Trees stabilize the soil. In the absence of trees and forests the fertile top soil is washed away by rainwater making cultivation impossible.
2. Trees prevent desertification. The famous Pink City, Jaipur is being encroached by desert due to the absence of trees.
3. Trees retain water in the soil. Without forests the entire rainwater flows into the sea. The water is then not available as ground water. Thus we experience flash floods followed by severe droughts. The underground water level also sinks and cultivation becomes impossible.
4. If deforestation continues unchecked and if afforestation is not taken up on a war footing, water management experts warned that there will be violent riots for water due to scarcity caused by droughts and pollution of rivers and lakes.
5. Trees are water bearer. Without trees rainfall will decrease and cultivation will become rather a matter of luck. Worldwide food scarcity causing famines is expected as food grain productions diminished due to low and unpredictable rainfall.
6. Trees are oxygen cylinders. Trees absorb the harmful Carbon dioxide and release Oxygen. Deforestation contributes to the decrease in oxygen level and increase Carbon dioxide in the atmosphere. Increased Carbon dioxide level results in lungs diseases, cancer and lower life expectancy.
7. Trees are air conditioners. Trees keep the temperature temperate. Trees and forests are habitats of wild birds and animals. Tree covered lands are the store house of many medicinal plants.
8. Trees also reduce air and noise pollution and add beauty to the landscape.
To save our home, the Earth, and all life in it people must prevent further felling of trees and start planting trees on a mass scale.
