The Amazon rainforest plays an important part in
regulating the world's oxygen and carbon cycles
. It produces roughly six percent of the world's oxygen and has long been thought to act as a carbon sink, meaning it readily absorbs large amounts of carbon dioxide from the atmosphere.
How the Amazon rainforest affects the world?
The Amazon rainforest contains
10 percent of all biomass on Earth
. It means that when deforestation takes place, the vast amounts of carbon that the forest stores are released into the atmosphere as carbon dioxide, a greenhouse gas that contributes significantly to global warming.
How do humans depend on the Amazon rainforest?
The Amazon River provides countless services for humans, such as
water for agriculture, transportation, and food
. In addition, the Amazon River provides an important habitat for countless species, including over 2500 species of fish and river dolphins.

help stabilise the climate
, playing a critical role in global and regional carbon and water cycles.
What happens if we lose the Amazon rainforest?
If the Amazon rainforest is destroyed,
rainfall will decrease around the forest region
. This would cause a ripple effect, and prompt an additional shift in climate change, which would result in more droughts, longer dry spells, and massive amounts of flooding.
Why is Amazon called the lungs of the world?
Amazon Rainforest–The most biodiverse region on earth
Billions of trees absorb tons of carbon dioxide every year and slow down the climate change along with producing 20% of earth's oxygen
, hence named ‘Lungs of Earth.
What is one of the biggest threat to rainforest?
Animal farming
is the largest destroyer of the Amazon rainforest. Agriculture accounts for 80% of deforestation, and the Amazon's forests are shrinking at an alarming rate. Livestock take an enormous amount of land to raise, meaning their geological footprint is much larger than crop farms.

Why is the rainforest so important to us?
As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By
absorbing carbon dioxide and releasing the oxygen
that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth's climate.
What type of sunlight does the rainforest get?
Although tropical rainforests receive
12 hours of sunlight daily
, less than 2% of that sunlight ever reaches the ground. The tropical rainforest has dense vegetation, often forming three different layers–the canopy, the understory, and the ground layer.
How many rainforest are left?
Using data from the forest monitoring program Global Forest Watch, Rainforest Foundation Norway found that only
36 per cent of
the planet's nearly 14.6 million square kilometres of tropical rainforest remains intact, while 34 per cent of it is completely gone and the remaining 30 per cent has been degraded.
Can the Amazon rainforest grow back?
Much of the Amazon's secondary forests are born from extensive pasture land that has lost its commercial productivity. … So as the rainforest soil loses its nutrients, many farmers move on to new areas, abandoning large areas of former pasture that then
regrow naturally
.
How long until Amazon rainforest is gone?
But recent trends reveal that the changing climate will likely come for this beloved rainforest long before the last tree is cut down. One researcher has even put a date on his prediction for the Amazon's impending death:
