Global environmental protection issues and their countermeasures


I. Climate change and greenhouse effect


Global climate change has become one of the biggest challenges facing the world today. Due to the large amount of greenhouse gas emissions generated by human activities, the earth's temperature has risen, which has caused a series of climate problems, such as the increase in the frequency and intensity of extreme weather events, melting glaciers, and rising sea levels. In response to climate change, the international community needs to work together to reduce greenhouse gas emissions, promote low-carbon economic development, and strengthen the construction of climate adaptation capabilities.


II. Sharp decline in biodiversity


Biodiversity is the cornerstone of the earth's life system. However, due to factors such as overexploitation, pollution and climate change, global biodiversity is facing serious threats. The rate of species extinction is accelerating and ecosystems are being destroyed. To protect biodiversity, it is necessary to strengthen biodiversity protection and sustainable use, promote ecosystem protection and restoration, and strengthen international cooperation to jointly respond to the challenges of biodiversity loss.


III. Water shortage and pollution


Water resources are the basis for human survival and development. However, water shortage and pollution problems are becoming increasingly serious worldwide. With population growth and economic development, the demand for water resources continues to increase, while water pollution and irrational use have exacerbated the problem of water shortage. To solve this problem, it is necessary to strengthen water resource management and protection, promote the construction of a water-saving society, and strengthen water pollution control to ensure water quality safety.


IV. Land degradation and desertification


Land degradation and desertification are another important issue facing global environmental protection. Factors such as excessive reclamation, unreasonable use and climate change have led to a decline in land quality and an expanding area of ​​desertification. This not only affects agricultural production, but also threatens ecological security and human survival. In order to cope with land degradation and desertification, comprehensive measures need to be taken to strengthen land use planning and management, promote ecological agriculture and land restoration, and promote sustainable land use.


V. Marine pollution and ecological damage


The ocean is an important part of life on Earth. However, with the continuous increase in human activities, marine pollution and ecological damage are becoming increasingly serious. Land-based pollution, oil pollution, plastic waste, etc. have had a serious impact on the marine environment, resulting in a decrease in marine biodiversity and an imbalance in the ecosystem. In order to protect the marine environment, it is necessary to strengthen marine pollution control, promote marine ecological protection and restoration, and strengthen the sustainable use and management of marine resources.


VI. Reducing Pollution Emissions and Clean Energy


Reducing pollution emissions and promoting clean energy are key measures to address global environmental protection issues. By strengthening the enforcement of environmental protection laws and regulations, raising pollution emission standards, and encouraging enterprises to adopt clean production technologies, pollutant emissions can be effectively reduced. At the same time, actively promote clean energy, such as solar energy, wind energy and other renewable energy, reduce dependence on fossil energy, reduce greenhouse gas emissions, and achieve sustainable use of energy.


VII. Establishment and management of nature reserves


Nature reserves are an important means to protect biodiversity and maintain ecological balance. By establishing nature reserves, rare and endangered species and ecosystems can be effectively protected to prevent human activities from causing damage to them. At the same time, strengthen the management and monitoring of nature reserves to ensure that they are effectively protected and managed, and provide strong guarantees for the protection of biodiversity and ecosystems.


In summary, global environmental protection issues involve multiple aspects, and the international community needs to work together to take comprehensive measures to address them. By strengthening international cooperation, promoting green development, strengthening the enforcement of environmental protection laws and regulations, and promoting clean energy, we can jointly protect our home planet and achieve the goal of sustainable development.

W10.2 May 10 (Fri)—CHENG SHIYI

1.Summary   Remix culture is a culture that allows and encourages the creation of derivative works through the editing of existing material, challenges exclusive copyright restrictions, promotes the idea of remixing, and facilitates the free flow of creativity. In Remix, Lessig describes the shift from a read-only culture to a read/write culture, where the advent of digital technology has redefined the way culture is created and distributed in ways that facilitate the interactive relationship between producers and consumers and democratize the production of ideas and the distribution of content. The history of remix culture dates back to the 19th century, e.g.: according to American media scholar Henry Jenkins, but the balance between creation and consumption shifted with the advancement of analog recording and reproduction technologies.The analog era of the early 20th century, with its specialized creative equipment and cheap consumer devices, led to the strengthening of proprieta...

How to make sure content you add to Wikipedia is not a copyright violation?—— LI MENGRU

1.Summary Firstly, we can use as much content as possible that is clearly released under free copyright licenses or is in the public domain. This content is typically available on dedicated free material websites, such as Wikimedia Commons, Pixabay, Unsplash, and others. Doing so can help avoid copyright disputes and ensure that the content we add is lawful. Secondly, if we wish to use others' work on Wikipedia, we must reach out to the copyright holders and request permission. This may require communication with the authors or copyright owners and obtaining written permission or usage agreements. Only after obtaining authorization can we use these works on Wikipedia. Additionally, we can choose to create our own original content and add it to Wikipedia. This not only helps avoid copyright issues but also contributes new and valuable content to Wikipedia. We can generate original content through independent research, interviews, or creation to enrich Wikipedia's information res...

W1.1 Intro class: intro to class, blog, wiki and other assignments——CHENG SHIYI

1. Summary  I have taken classes from you, the professor, before and have always been interested in Wikipedia, so I chose to take your class this semester regardless. I understand from your introduction to all the courses in the lecture that this semester's Collective Intelligence in Practice course is centered around Wikipedia, which I understand is an encyclopedia that anyone can edit, and that Wikipedia brings together knowledge from around the world. One of the quotes in your course syllabus is that Technocrati's chief technologist says that soon "Wiki-knowledge will be a required job skill." Wikipedia, a non-profit encyclopedic website, is ranked among the top 5 most popular websites in the world, all thanks to a little bit of contribution from volunteers in the world. I see from this that the Collective Intelligence in Practice program understands Collective Intelligence on the Internet through Wikipedia from a sociological perspective. There are many ways to s...
