Why does the state of tropical rainforests have an impact on the planet?

Tropical rainforests have a significant impact on the global environment because they can maintain the carbon and oxygen balance of the atmosphere. Because the tropical rainforest has a very large role in spitting out the old and absorbing the new, and it can also be called the lungs of the earth.

If the rainforest has suffered a series of damages, then a large amount of carbon dioxide will be released into the atmosphere, and the consequences are really conceivable.

Second, tropical rainforests contribute to the global water cycleIn this way, the global water balance can be regulated. Because the tropical rainforest is a sponge in nature, it can absorb and store a large amount of rainwater, and then through its own evaporation, it returns rainwater back to the atmosphere and slowly forms rainwater.

In fact, the role of tropical rainforests in the whole forest is more prominentFor example, about 50% of the precipitation in the Amazon is due to the rainforest itself. So we can see how important rainforest precipitation is to the amount of water across the globe.

In fact, the water vapor produced by the normal function of tropical rainforests not only forms a large amount of rain, but also affects other countries and regions. This slowly increases the amount of water in the atmosphere, and it can be said that the whole rainforest is the home of clouds and rain.

But if you think about it from another angle, if we destroy the rainforests, then there will be a significant change in the amount of precipitation around the world.

And the tropical rainforest is a treasure trove of the world's genes, because among the entire global vegetation, the tropical rainforest has the oldest plant communityIn the process of biological evolution, more species can be reproduced, which can also protect the safety of these species for a longer time.

Now, due to the difficulty of artificial development, the area of tropical rainforests has begun to slowly decrease, which has also led to the gradual acceleration of the extinction rate of some species.

In the theory of nature conservation, human beings should respect nature, and although this is a moral commitment, nature is not the object of human exploitationAll species have the right to live.

Human beings are also part of the natural world, and throughout lifeHumans are only a part of what came later, so they have no right to harm other species.

Because the climate of tropical rainforests can affect some climate development in other places, it will also cause certain natural disasters and affect the stable development of the earth.

It is because the climate in the tropical rainforest is relatively changeable, and the climate here affects the global climate, so it will have a certain impact on the earth's environment.

Because if a tropical rainforest is hit by fire, then it will destroy the ecological balance of the earth, it will make many animals homeless, let trees die, and cause things that pollute the air.

Because the rainforest is a very critical place, and secondly, it has a great impact, and some of the organisms and plants that grow are very special.

The causes of tropical rainforest climate are mainly influenced by latitude factors.

1. Solar radiation: The amount of solar radiation is in the range of 100-180 kcal centimeters per year. makes it high temperatures throughout the year. Areas with even more intense solar radiation will become deserts.

2. Atmospheric circulation: Located in the equatorial low pressure zone, the trade winds gather near the equator, converge and rise, and the water vapor contained in it is easy to form clouds and cause rain.

3. Influence on land and sea. The tropical rainforest climate is located near the sea or in large river basins, which gives it abundant rainfall and small temperature differences. The terrain is low, which is suitable for rainforest growth.

4. Vegetation affects the transpiration of trees strongly, making the environment more humid.

Characteristics of tropical rainforests.

1. The tropical rainforest is a kingdom of trees, and it is extremely rich in species.

2. In this environment with suitable hydrothermal conditions, the competition for light and living space is extremely strong.

3. The special prosperity of lianas and epiphytes is a special adaptation mode for competing for space, which has a great impact on the forest structure.

4. The variety of animals is also rich and diverse. Arbors with many tabular roots, aerial root plants or lianas, obvious systematic stratification, tall trees, and rich plant varieties; Because the weather is warm for a long time and the rainfall is high, the plants can continue to grow, resulting in dense and green trees.

The three largest tropical rainforests on Earth.

One. Indo-Malay rainforest biome.

Asian rainforests are mainly distributed in the Philippine Islands, the Malay Peninsula, the east and west banks of the Indochina Peninsula, the lower reaches of the Ganges River and the Brahmaputra River, the southern part of Sri Lanka and the southern part of China. It is characterized by the dominance of dipterocarp and the lack of plants with beautiful large flowers and particularly tall palmaceae, but with tall woody true fern alder alsophila and the famous white vine (calamus) and orchid epiphytes.

Two. African rainforest biome.

One of the three largest tropical rainforests in the world. The African rainforest community is small in size, about 6, and is mainly found in the Congo Basin. South of the equator to the eastern coast of Madagascar and other islands.

African rainforests are poorer in species but have a large number of endemic species. Among them, palm plants are particularly noteworthy, such as palm, oil coconut, etc., and there are many species of Coffea (35 species in the world, 20 in Africa). However, in West Africa, the neem family is dominant, and leguminous plants also have a certain advantage.

Three. American rainforest biome.

One of the three largest tropical rainforests in the world. The group is the largest, over 3, centered on the Amazon River, extending westward into the lower foothills of the Andaz Mountains, ending in Guyana in the east, Bolivia and Paraguay in the south, and southern Mexico and the Antilles in the north. The legume family is the dominant family here, and there are many lianas and epiphytes, as well as bromeliads, cactiaceae, araceae and palmaceae.

Cash crops such as heveabrasiliensis, cocoa and coconut are all native to the region. It also grows the endemic royal lotus (Victoria Regia), whose leaves can reach diameter.

The world's rainforests are divided into three major groups: the Amazon basin in South America, the Congo Basin and the Gulf of Guinea coast in Africa, most of the Malay Archipelago in Asia, and the southern Malay Peninsula.

Tropical rainforests are found in tropical rainforest climate zones. The tropical rainforest climate on Earth is mainly found near the equator and in some parts of the eastern continent near the Tropic of Capricorn.

The most concentrated areas of tropical rainforests on the earth include the Amazon Plain in South America, the Congo Basin in central Africa, and the Malay Archipelago in Southeast Asia. The tropical rainforests in the eastern part of the continent near the Tropic of Cancer are mainly northeastern Central America, southeastern Madagascar in Africa, northeastern Australia, and southeastern Brazil. The area of tropical rainforest in these areas is relatively small.

<> as shown in the figure above, the four regions of A-D are non-zonal rainforest (climate) distribution areas. Among them, a is the eastern part of the island of Madagascar; b is northeastern Australia; c is southeastern Brazil; d is the western part of the Central American Isthmus; They are not formed by the equatorial low pressure all year round, as is the case in the Congo Basin and the Amazon rainforests.

The main causes of this are:1It is located in the tropical low altitude area, with high temperatures all year round; 2.

The ocean trade winds bring water vapor and are located on the windward side of the trade winds, with a lot of precipitation. 3.There is a warm current passing along the coast, and the warming and humidification effect is significant. Wait a minute.

Where are the rainforests located? Why are tropical rainforests the lungs of the planet? On the planet on which we live, tropical rainforests are the most widely distributed forests with the largest variety of flora and fauna. They have a very close relationship with the living environment of human beings.

Tropical rainforests are mainly found in Southeast Asia, Central Africa, northern South America, and parts of Europe. Before the middle of the 20th century, there was little mention of it in human activity. At that time, the deserts on Earth were much smaller than they are now, the variety and number of plants and animals were much larger than they are now, and natural disasters were much more frequent than they are now.

In previous evolutionary history, it took about 1,000 years for plants to become extinct. But in 1980, the extinction of one plant was reached every day. In the 90s of the 20th century, plant species disappeared even faster, reaching the extinction of one per hour.

Of the more than 250,000 known flowering plants, two-thirds are found in the tropics. Of these, 25,000 are already in danger of extinction. The area of tropical rainforests in South-East Asia and South America was reported to have decreased over a five-year period from 1993 to 1998.

Currently, the world's tropical rainforests are being deforested, burned or destroyed by chemicals at a rate of 20 hectares per minute. If the destruction of tropical rainforests is not effectively controlled, 25% of the birds and plants living in tropical rainforests will be at risk of extinction by 2025, equivalent to 10,000 times the rate of natural extinction of species.

Tropical rainforests play an important role in regulating the global ecosystem, and if forests disappear, deserts will expand dramatically. Only 2% of the tropical rainforest on the Atlantic coast remains, but the neighboring Peruvian desert has expanded. Africa's Sahara Desert continues to push southward, with drought threatening the desert savannah regions of West Africa, also as a result of the region's loss of rainforests.

Frequent floods, droughts, and a warming climate on the planet are all linked to the shrinking area of tropical rainforests. Tropical rainforests are a natural gene pool. According to expert surveys, there are 10,000 species of plants found in the tropical rainforests of South America alone, and if the destruction of forests continues, most people will disappear if they are not found and used.

Plants are not only the best for all of our food and half of our medicines, but also the natural "oxygen" that purifies the air and makes oxygen. Tropical rainforests are thus called the "lungs of the earth".

Tropical rainforests are mainly found in tropical areas near the equator. The reason why tropical rainforests are the lungs of the earth is that tropical rainforests have many trees and greenery, which are basically fully covered, can produce a lot of fresh oxygen, and are pollution-free.

Generally speaking, it is more abundant in South America, but also in the Congo Basin in Africa. Because there are a lot of swamps in this place, and the trees are very vigorous.

1. Biodiversity and genetic diversity have declined sharply;

2. The increase in the concentration of carbon dioxide in the atmosphere has led to global warming, and the sea level has risen and the coastal areas have been inundated; Wisdom is empty.

3. Soil erosion, flooding before floods and droughts.
