Trees increases the beauty of earth!♥
☼Trees combat the greenhouse effect
Global warming is the result of excess greenhouse gases, created 由 burning fossil fuels and destroying tropical rainforests. Heat from the sun, reflected back from the earth, is trapped in this thickening layer of gases, causing global temperatures to rise. Carbon dioxide (CO2) is a major greenhouse gas. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when 你 drive your car 26,000 miles.☼
♥Trees clean the air♥
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air 由 trapping them on their leaves and bark.
♥Trees provide oxygen♥
In one 年 an acre of mature trees can provide enough oxygen for 18 people.
♥Trees cool the streets and the city♥
Average temperatures in Los Angeles have risen 6°F in the last 50 years as 树 coverage has declined and the number of heat-absorbing roads and buildings has increased.
Trees cool the city 由 up to 10°F, 由 shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.
♥Trees conserve energy♥
Three trees placed strategically around a single-family 首页 can cut summer air conditioning needs 由 up to 50 percent. 由 reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.
♥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.
♥Trees help prevent water pollution♥
Trees reduce runoff 由 breaking rainfall thus allowing the water to flow down the 树干 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.
♥Trees help prevent soil erosion♥
On hillsides 或者 stream slopes, trees slow runoff and hold soil in place.
♥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 由 about 50 percent, thus providing protection to children on school campuses and playgrounds - where children spend hours outdoors.
♥Trees provide food♥
An 苹果 树 can yield up to 15-20 bushels of 水果 per 年 and can be planted on the tiniest urban lot. Aside from 水果 for humans, trees provide 食物 for birds and wildlife.
♥Trees heal♥
Studies have shown that patients with 查看 of trees out their windows heal faster and with less complications. Children with ADHD 显示 fewer symptoms when they have access to nature. Exposure to trees and nature aids concentration 由 reducing mental fatigue.
♥Trees reduce violence♥
Neighborhoods and homes that are barren have shown to have a greater incidence of violence in and out of the 首页 than their greener counterparts. Trees and landscaping help to reduce the level of fear.
Trees mark the seasons
Is it winter, spring, summer 或者 fall? Look at the trees.
♥Trees create economic opportunities♥
水果 harvested from community orchards can be sold, thus providing income. Small business opportunities in green waste management and landscaping arise when cities value mulching and its water-saving qualities. Vocational training for youth interested in green jobs is also a great way to develop economic opportunities from trees.
♥Trees are teachers and playmates♥
Whether as houses for children 或者 creative and spiritual inspiration for adults, trees have provided the 太空 for human retreat throughout the ages.
♥Trees bring diverse groups of people together♥
树 plantings provide an opportunity for community involvement and empowerment that improves the quality of life in our neighborhoods. All cultures, ages, and genders have an important role to play at a 树 planting 或者 树 care event.
♥Trees add unity♥
Trees as landmarks can give a neighborhood a new identity and encourage civic pride.
Trees provide a canopy and habitat for wildlife
Sycamore and oak are among the many urban species that provide excellent urban homes for birds, bees, possums and squirrels.
♥Trees block things♥
Trees can mask concrete walls 或者 parking lots, and unsightly views. They muffle sound from nearby streets and freeways, and create an eye-soothing canopy of green. Trees absorb dust and wind and reduce glare.
♥Trees provide wood♥
In suburban and rural areas, trees can be selectively harvested for fuel and craft wood.
♥Trees increase property values♥
The beauty of a well-planted property and its surrounding 街, 街道 and neighborhood can raise property values 由 as much as 15 percent.
♥Trees increase business traffic♥
Studies 显示 that the 更多 trees and landscaping a business district has, the 更多 business will flow in. A tree-lined 街, 街道 will also slow traffic – enough to allow the drivers to look at the store fronts instead of whizzing by.
Tree!♥..see it looks preety:)
