まとめ
法律の変更により,保護区域の格下げ,縮小,撤廃 (PADDD) により,保護区域が弱体化しています. これらのPADDD現象は,しばしば資源の採掘に関連しており,世界中の生物多様性保全の取り組みを脅かしています.
科学分野:
- 保護科学
- 環境法
- 生物多様性の管理
背景:
- 保護地域は生物多様性の保全に不可欠です.
- 法律の変更により 保護区の整合性と効果が 損なわれることが 明らかになっています
- 保護区の格下げ,縮小,およびガゼット化 (PADDD) 事件は重大な脅威を意味する.
研究 の 目的:
- アメリカ合衆国とアマゾンの国々でのPADDDの出来事を記録し分析する.
- PADDDイベントに関するグローバルなデータを収集し,評価する.
- 生物多様性の保全のためのPADDDの動機と影響を理解する.
主な方法:
- 各国のPADDDイベントを体系的に記録する.
- 保護区に影響を与える法的変化に関する過去のデータの収集
- PADDDの出来事と産業発展の関連性の分析
主要な成果:
- 米国とアマゾン諸国はそれぞれ269件と440件のPADDDが発生しました.
- 世界では1892年から2018年の間に73カ国で3,749件のPADDDが発生し,210万平方キロメートル以上の地域に影響を与えました.
- 世界のPADDDの78%は2000年以降に発生し,そのうち62%は資源の採掘と開発に関連しています.
結論:
- PADDD現象は広範囲に広がり,保護区の目標が損なわれています.
- 産業規模での資源採掘はPADDDの主な要因である.
- 保護区の長期的効果と生物多様性の保全を確保するために,緊急の政策介入が必要である.

The Colonization of Land
37.5K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Zones of Protection
785
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

Protection of Alcohols

This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Protecting Self-Esteem
204
Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...

Radial System Protection
431
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

States of Water

Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
