In the United States, which contains 8 percent of the world's forests, there are more trees than there were 100 years ago. According to the Food and Agriculture Organization (FAO), "Forest growth nationally has exceeded harvest since the 1940s.
Tree cover increased globally over the past 35 years, finds a paper published in the journal Nature. The study, led by Xiao-Peng Song and Matthew Hansen of the University of Maryland, is based on analysis of satellite data from 1982 to 2016.
True or False: There are more trees today than there were 100 years ago. The good news is that the answer is a resounding “TRUE”! According to the Food and Agriculture Organization (FAO), “Forest growth nationally has exceeded harvest since the 1940s”.
Since the onset of the industrial era, forests have declined by 32%. Especially in the tropics, many of the world's remaining three trillion trees are falling fast, with about 15 billion cut each year, the Nature study states. In many places, tree loss is accelerating.
How many trees were there 100 years ago? About 70 million trees. The early 1920's defined an exponential growth in the timber industry due to the developments that were happening in the construction and recreation industry. This made it one of the key drivers for deforestation in the US.
According to Global Forest Watch, the world lost 411 million hectares of forest between 2001 and 2020. That's roughly half the size of the United States and equivalent to 10 percent of global tree cover. In 2020, the world lost a near-record 25.8 million hectares — almost double the amount in 2001.
Taken in aggregate, the new data shows that forests around the world continue to decline, with the highest rates of loss occurring in the most pristine ecosystems that account for a disproportionate share of biodiversity, carbon sequestration, and Indigenous communities.
? NASA: The Earth is greener now than it was 20 years ago. The Earth has become five percent greener in 20 years. In total, the increase in leaf area over the past two decades corresponds to an area as large as the Amazon rainforests. The earth is literally getting greener.
There might be 3.04 Trillion trees in the world, but their distribution is the real problem. 50% of all the trees in the world are present in the five biggest countries, while two-thirds of all trees are in just ten countries. Leaving just 1990 Billion trees for the rest of the world!
Causes of deforestation
In the Amazon, cattle ranching and farms—particularly soy plantations—are key culprits. Logging operations, which provide the world's wood and paper products, also fell countless trees each year.
New numbers estimate there are about 420 trees on Earth for every human. There are more trees on Earth than stars in our galaxy. A new study estimates there are just over three trillion trees on Earth. This means that there are around 420 trees for every human on the planet.
And the least tree-filled countries? There are five places with no forest whatsoever, according to World Bank's definition* - Nauru, San Marino, Qatar, Greenland and Gibraltar - while in a further 12 places there is less than one per cent.
Number of Trees Removed in The Last 100 Years
According to the UN, Food and Agricultural Organisation (FAO)'s forest report State of the World's Forests 2020, there has been a 13% decrease in forest cover over the past 100 years. This, therefore, equates to approximately 3.9 billion trees removed in the past 100 years.
Net forest area in the U.S. has been stable since the early 1900s and increased by about 2% from 752 million to 765 million acres between 2007 and 2017. Net volume of growing stock increased by more than 5% over the same period.
That's 6 billion hectares. Today, only 4 billion hectares are left. The world has lost one-third of its forest – an area twice the size of the United States. Only 10% of this was lost in the first half of this period, until 5,000 years ago.
Conclusion: Earth is losing its greenery due to many factors including an increasing number of houses and agriculture. We need to take steps to increase forest cover to restore nature. There is a need to balance the development and restoration of the environment.
Growing energy requirements led to the clearing up of large tracts of land for solar energy, wind energy and other power plants. Increasing forest fires are causing even more loss of forest cover. Decreasing air moisture due to climate change is causing declining plant growth.
Changing land use for food production is the biggest driver of nature loss. About 50% of the world's habitable land area is already used for agriculture – for livestock such as cattle and pigs and for crops that feed both people and livestock.
From 2001 to 2021, United States lost 44.3Mha of tree cover, equivalent to a 16% decrease in tree cover since 2000, and 17.4Gt of CO₂e emissions.
Study reveals the Earth is on track to run out of trees in 300 years.
1 BILLION hectares cut down in 40 years
In just 40 years, a forest area the size of Europe has gone. Half of the world's rainforest has been destroyed in just one century. If we don't act and the current rates of deforestation continue, the world's rainforests will be gone in 100 years.
Half of the forests that originally covered 48 percent of the Earth's land surface are gone. Only one-fifth of the Earth's original forests remain pristine and undisturbed.
Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down from 16 million hectares per year in the 1990s. The area of primary forest worldwide has decreased by over 80 million hectares since 1990.
If the current rate of deforestation continues, the world's rain forests will vanish within 100 years- causing unknown effects on global climate and eliminating the majority of plant and animal species on the planet.
