- 环境科学 环境科学
- 环境政策 环境政策
- 循环经济是一个循环经济.
背景情况:
- 环境可持续性是一个关键的全球挑战.
- 越来越多地实施绿色经济倡议 (GEI),以解决环境问题.
- 衡量GEI对环境可持续性的影响需要强大的实证分析.
研究的目的:
- 实证地评估各种绿色经济倡议 (GEI) 对环境可持续性的影响.
- 确定哪些特定的GEI指标对环境指标影响最大.
- 为决策者提供关于绿色经济投资的基于证据的建议.
主要方法:
- 分析了来自19个欧洲国家的数据,涵盖2012-2019年的时间.
- 使用六个指标来量化GEI:循环材料消耗 (GEI_MA),每人城市废物产生 (GEI_MW),废物回收性能 (GEI_RW) 和与回收和二次原材料相关的专利 (GEI_PA),包括生物废物 (GEI_RB) 和电子废物 (GEI_RE) 的回收份额.
- 统计分析以确定GEI指标对生态绩效指数 (EPI),生态足迹 (ECO),人类健康 (HLT) 等环境指标的影响.
主要成果:
- 每人市政废物产量 (GEI_MW) 显著改善了EPI和ECO.
- 循环材料消耗 (GEI_MA) 和废物回收性能 (GEI_RW) 显示出对EPI和ECO的强烈积极影响.
- 生物废物 (GEI_RB) 对EPI,HLT和ECO产生积极影响,而电子废物 (GEI_RE) 对HLT和ECO产生积极影响. 在GEI_PA和生态可持续性之间没有发现显著的联系.
结论:

01:43Sustainable Development
13.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

7.2K
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

01:50Global Climate Change
24.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:17Thermal Electrocyclic Reactions: Stereochemistry
2.0K
The stereochemistry of electrocyclic reactions is strongly influenced by the orbital symmetry of the polyene HOMO. Under thermal conditions, the reaction proceeds via the ground-state HOMO.
Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

00:54What are Biogeochemical Cycles?
31.3K
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.
