Natural forest systems are a critical part of the world’s biodiversity as more forests are biodiversity than other species. Forests cover 31 percent of the world’s land area about half of the forest area is compact, and more than one-third of the main forest (meaning forests are naturally regenerated of indigenous species, where there are no visible indications of human activities and natural processes that are less disturbed). The total forest area is 4.06 billion hectares or approximately 5 000m2 (or 50 x 100m) per person, but forests are not evenly distributed across the globe.
More than half the world’s forests are found in only five countries (Russia Federation, Brazil, Canada, United States of America, and China) and two-thirds (66 percent) of forests are found in ten countries.

Deforestation and deforestation continue to occur at alarming rates, which contribute significantly to the continued loss of biodiversity. Since 1990, it is estimated that 420 million hectares of forest have been lost through alternative land use, although deforestation rates have declined over the past three decades.
Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, dropping from 16 million hectares per year in the 1990s. The area of the world’s largest forest has shrunk by more than 80 million hectares since 1990.
Agricultural expansion continues to be a major catalyst for deforestation and deforestation and loss associated with forest diversity. Large-scale commercial agriculture (mainly cattle ranching and soybean and palm oil planting) accounted for 40 percent of tropical deforestation between 2000 and 2010, while domestic subsistence agriculture received another 33 percent.
Forest species and genetic diversity
It is not only the trees that make up the forest but many species of plants and animals that live in the ground, underground, and in the snow. Estimates of the total number of species on earth from 3 million to 100 million (May 2010). Although it is widely reported that forests contain 80 percent of the world’s plants and animals, such estimates are unlikely to be accurate given the changing nature of the world’s biological knowledge. While trees are a descriptive part of forests and their diversity may provide an indication of total diversity, there are many other ways to determine the value of forest diversity.
Variety of forest species: Trees
The Global Tree Search database reports that there are several types of trees about half of all drugs (45 percent) belong to just ten families. 58% about 58 percent of all tree species belong to the same country. As of December 2019, 20 334 tree species have been included in the IUCN Red List of Threatened Species (IUCN, 2019a), of which 8 056 have been evaluated as global threats (high-risk, endangered, or endangered). More than 1,400 species of trees are considered to be endangered and in need of urgent conservation action.
How much rainforest is left in the world?
Using data from the Global Forest Watch Forest Monitoring Project, Rainforest Foundation Norway found that only about 14.6 million square feet of the planet’s tropical rainforest remains intact, with 34 percent permanently lost and the remaining 30 percent degraded.
“The good news is that we still have half the size of Europe,” said Anders Kroc, Norwegian special adviser to the Rainforest Foundation and the report’s author. “however, the remaining tropical forests may be severely damaged or further subdivided. People are cutting down formerly vast and impenetrable forests into smaller and smaller pieces, weakening their ability to store carbon , cooling the planet, producing rainwater and providing habitat. The world depends on tropical rainforests to provide these services.”
Using the data source, the researchers were able to collect data from each of the 73 countries around the world that belong to tropical rainforests. We now know how many tropical rainforests there are in the world and the state in which it exists, and we compare this to estimates of how many tropical rainforests existed before modern human invasion,” Kroc said in the release. “This knowledge is vital to wage a global war to save the rest. It is worrying that nearly half of the world’s rainforests are lost.”
Asia is particularly affected by tropical deforestation, the study said. For example, the island of Sumatra in Indonesia has only nine percent of its native tropical rainforest. The continent now contains only seven percent of the world’s tropical rainforests.In addition, between 2002 and 2019, global deforestation contributed to the loss of tropical rainforests, the size of France, and planetary tropical rainforests the size of Belgium each year. Deforestation of tropical forests began in the early 19th century to meet the growing demand for rubber to provide for the widespread production of cars. Today, deforestation in these areas is commonly used for international trade and the production of products such as soybeans, palm oil and minerals.
“These particular ecosystems are suffering from constant and recurring abuse from our perpetual hunger for land and resources,” Kroc said The Amazon rainforest is the largest rainforest in the world with an area of 6,000,000 km (2316612.95 sq mi). It represents more than half of the planet’s rainforests and contains the world’s largest and most diverse biodiversity. The region is owned by nine countries. Most of the forests are within 60% of Brazil, followed by Peru at 13%, Colombia at 10%, and smaller ones in Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana.
The Amazon beef sector, which is an international beef and skin promoter, is responsible for deforestation of about 80% of the region, or about 14% of the total annual deforestation. which is the world’s largest single drive deforestation. Most of the agricultural activities caused by deforestation are supported by government tax revenue. By 1995, 70% of the forest in the Amazon and 91% of the land destroyed since 1970 had been converted to livestock. The destruction of most of the remaining forests within the Amazon resulted in farmers switching to small-scale subsistence farming (sometimes using the cutting-and-burn method) or mechanized plantations that produced soybeans, palms, and others. To cultivate the land. Crops.
More than a third of the Amazon rainforest is native to more than 3,344 formally recognized inland regions. As of 2015, only 8% of Amazon’s deforestation occurred in forests inhabited by indigenous peoples, while 88% is not home to less than 50% of the Amazon territory or protected area. Historically, the livelihoods of native Amazonians relied on forests for food, shelter, water, fiber, fuel, and medicine. Forests are intertwined in their identity and cosmology. For this reason, deforestation rates in native regions remain low, despite pressures that encourage deforestation to remain strong.
According to satellite data in 2018 compiled by a deforestation monitoring program called Broads, deforestation has reached its highest rate in a decade. About 7,900 km (3,050 sq mi) of rainforest was cleared between August 2017 and July 2018. Most of the deforestation took place in the states of Mado Grosso and Barre. The BBC has blamed Environment Minister Edson Duterte for the illegal logging, but critics say the expansion of agriculture is also entering the forest. At some point the forest is said to reach a climax where it can no longer receive enough rainfall to sustain itself.
