Benefits of Tree.

Trees combat the greenhouse effect

Monterosso

Global warming is the result of excess greenhouse gases, created by 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 you drive your car 26,000 miles.

Trees clean the air

Monterosso

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.

Trees cool the streets and the city

Monterosso

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.

Trees help prevent water pollution

Monterosso

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.

Trees are carbon sinks

Monterosso

The main natural carbon sinks are plants, the ocean and soil. Plants grab carbon dioxide from the atmosphere to use in photosynthesis; some of this carbon is transferred to soil as plants die and decompose. The oceans are a major carbon storage system for carbon dioxide. Trees help prevent soil erosion On hillsides or stream slopes, trees slow runoff and hold soil in place.

Trees shields from ultra-violet rays

Skin cancer is the most common form of cancer in the northern world. Trees reduce UV-B exposure by about 50 percent.

Trees act as sound barriers to reduce noise pollution.

Monterosso

Noise abatement has become an important consideration for many municipalities as they constantly look at ways of suppressing and dampening surrounding noise from nearby roads, railways, and airports. Urban trees can be used as sound barrier to reduce noise pollution. As with planting for wind or visual barriers, the selection and arrangement of the trees is key to a successful outcome. Where solid barriers such as fences are frequently used as sound barriers, trees and shrubs can also be effective. Where space permits, thick strips of vegetation in conjunction with landforms or solid barriers can reduce highway noise by 6 to 15 decibels (D.I. Cook). Because trees absorb more high frequency noise than low frequency, this makes them ideal for use as sound barriers.

Trees provide food

Monterosso

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.

Trees provide a canopy and habitat for wildlife

Monterosso

Sycamore and oak are among the many urban species that provide excellent urban homes for birds, bees, possums and squirrels. Trees absorb carbon dioxide from the atmosphers, Chlorophyll with the help of sun light breaks carbon dioxide in to carbon and oxygen. Carbon is converted in to wood and oxygen is released in to the atmosphere.
