Introduction

A tree is like a humidifier.
A medium-sized tree turns water into steam every year through leaves, and then evaporates 4,000 kilograms of
waterinto the air like a sprayer to moisten the air.

A tree is like a vacuum cleaner.
The total leaf area of a medium-sized tree is as large as two mu of land. It can retain a large amount of dust, reduce
the amount of falling dust by 23%-55%, and reduce the amount of floating dust by 37%-60%.

A tree is like an oxygenerator.
A medium-sized tree can release 1.8kg of oxygen per hour, and the oxygen produced during the day can meet the
needs of 64 people.

A tree is like a toxic substance remover.
A tree sometimes absorbs more than 10 kinds of toxic gases.

Scientific research shows that: On average, trees absorb 1.83 tons of carbon dioxide and release 1.62 tons of oxygen
per cubic meter of growth. The United Nations Intergovernmental Panel on Climate Change (IPCC) estimates that
the global terrestrial ecosystem carbon stock is about 248 trillion tons. Forests, which are the largest carbon pool
of terrestrial ecosystems, store about 1.15 trillion tons of total carbon. According to the receipt of the seventh forest
resources inventory, China's forests absorb more than 500 million tons of carbon dioxide every year, accounting
for about 8-10% of industrial emissions in that year. Afforestation and reforestation to increase forest carbon
sequestration is recognized as the most cost-effective way to solve the rise of CO2 in the world.

The greening area is about 830,000 square meters, covering 128 kinds of green plants. Relevant research data show
that each adult tree can absorb 12kg of carbon dioxide per year. At present, nearly 15,000 large arbors are planted
across various plants of BBAC, which can absorb about 160 tons of carbon dioxide every year.
