Accelerating"deforestation"current situation | 5 environmental impacts occurring on the earth.
Oxygen, which is indispensable for us to live, is produced by plants such as trees and flowers, which exist in large numbers on the earth, and most of the gas balance is maintained in forests.However, the area of forests in the world is teethの森林面積は、Did you know that we are destroying 5.2 million hectares per year at an astonishing rate?？ This time, I will explain what is happening in the earth's forests with the theme of the current state of deforestation.します。

Current status of deforestation
What is deforestation

At this rate, tropical forests will disappear.る？
One theory is that if current levels of deforestation progress,は、It is said that the world's rainforests will disappear completely in just 100 years.。 （From a National Geographic studyCauses of deforestation
Commercial logging by developed countries is the main cause of deforestation, which has accelerated sharply over the past 50 years採。Most of the timber harvested in developing countries is transported to developed countries for mass consumption.す。 In addition, there is no end to forest fires caused by droughts, lightning strikes, and rising temperatures due to global warming.絶たず、The number of fires in the Amazon rainforest in 2019 has already exceeded 70,000, the highest number in recorded history.。
Environmental impact of deforestation響
I don't think there are many people who know how deforestation actually harms the earth, to the extent that they don't feel good about the lack of green nature.Forests are a complex ecology that affects almost all living things on earth. Excessive area reduction in a system would cause catastrophic problems worldwide.問題を引き起こします。
- Increased greenhouse gas emissions
- Impact on ecosystem biodiversity響
- Decrease in water circulation water source recharge function下
- Intensification of soil erosion
- Development into many other social problems Decline in quality of life Poverty conflicts, etc.・紛争等）
(1) Increase in greenhouse gas emissions
Greenhouse gases, which are said to be the main cause of global warming, are a general term for gases that have a greenhouse effect on the earth. Ozone, carbon dioxide, methane, etc. When the corresponding trees are felled, the carbon dioxide stored in the trees is released into the atmosphere. For気へ放出されるため、Deforestation contributes significantly to rising greenhouse gas emissions。 ※Carbon dioxide emissions from deforestation are the world's second largest source of emissions after the burning of fossil fuels.The impact of increased greenhouse gases is not limited to global warming, but can also cause climate change, including extreme weather events such as hurricanes. pointed outています。
(2) Impact on ecosystem biodiversity響
About 70 of the world's plants and animals live in forestsが、Deforestation causes them to lose their habitat。 It is clear that the loss of habitats leads to the extinction of species and deprives the local people of valuable sources of nutrition. There are already real damages such as a decrease in the number of animals and the restriction of habitats for insects such as honeybees, affecting other animals and plants.いるのです。
(3) Decrease in water circulation water source recharge function下
Water resource recharge functionは、 A function that stabilizes the mass of a river by adjusting the amount of water flowing into the river by storing rainwater in the soil of the forest.のこと。 In other words, if the water resource recharge function declines due to deforestation,と、It can cause flooding of rivers during heavy rains and exacerbate droughts when the rain stops.ます。 As will be described later in ⑤, water is a lifeline for humankind, and if the water supply is not stabilized, it is feared that it may develop into social problems such as conflict poverty.ます。
④ Intensification of soil erosion
Because the forest stabilizes the soil with the roots of each treeめ、Deforestation leads to severe soil erosion。 Soil erosion is the erosion of soil by the action of rain, water and wind. Floods and landslides, etc. due to intensification.地域の水質の低下、最終的にはThe deterioration of the health condition of the residents of the area is seen as a problem.。
⑤ Deforestation causes many social problemsす！
We Japanese don't have to worry about food to some extent, and we can drink clean water wherever we go and spend the summer in a relatively cool environment. as you can seeお分かりの通り、Deforestation is not only an effect on the atmosphere, but it is a phenomenon that is viewed as a problem from various perspectives, such as an increase in environmental refugees, poverty, conflicts, and the possibility of further secondary disasters.なのです。
Summary What we can doは？
Fundamental solutions to prevent the worsening of deforestation, one of the global environmental problems, require countermeasures by the entire country and government industry.策が必要です。However, I think it is important for us as individuals to take an interest in this issue and practice what we can do around us.思います。 I have compiled an example of forest conservation activities that can be practiced immediately from today.した。
