A study on Plastic Pollution

A recent study says that India has secured the top spot as biggest plastic polluter in the world, releasing 9.3million tonnes (Mt) annually, amounts to roughly one-fifth of global plastic emissions.

Findings of the study

  • The study defined plastic emissions as materials that have moved from the managed or mismanaged system (controlled or contained state) to the unmanaged system (uncontrolled or uncontained state, the environment).
  • Of the unmanaged waste, roughly 43% or 22.2 mt is the form of unburned debris and the rest, some 29.9 mt, is burnt either in dumpsites or locally.
  • Global findings - Globally, roughly 69% or 35.7 Mt per year of the world’s plastic waste emissions come from 20 countries, of which
    • 4 are low-income countries,
    • 9 are lower-middle-income countries and
    • 7 are upper-middle-income.
  • Furthermore, high-income countries have higher plastic waste generation rates, but none are ranked in the top 90 polluters, as most have 100% collection coverage and controlled disposal.
  • Littering was the largest emission source in the Global North, uncollected waste was the dominant source across the Global South.
  • In India – India has secured the top spot as biggest plastic polluter in the world, releasing 9.3 million tonnes (Mt) annually, amounts to roughly one-fifth of global plastic emissions.
  • India’s official waste generation rate, approximately 0.12 kilograms per capita per day.

Top 10 plastic polluters

  • Taking the 2nd and 3rd spots were Nigeria, with 3.5 Mt of emissions and Indonesia, with 3.4 Mt.

Global Plastics Treaty

  • In 2022, World Countries agreed to develop a Treaty on plastic pollution by 2024 to reduce greenhouse gas emissions from plastic production, use and disposal.
  • The Global Plastics Treaty is a legally binding agreement between over 175 United Nations member countries to reduce the use of plastics.
  • Goals - Reducing plastic production - Setting deadlines for countries to reduce plastic production.
  • Eliminating unnecessary uses - Banning certain uses of plastics that create waste.
  • Prohibiting certain chemicals - Banning specific chemicals used in the production of plastics.
  • Setting recycling goals - Setting targets for recycling plastics.
  • Addressing the entire lifecycle of plastics - The treaty addresses the entire life cycle of plastics, from design to production to disposal.
  • Considering vulnerable workers - The treaty may consider the impact on vulnerable workers.
  • Chemical testing mandates - The treaty may include mandates for testing certain chemicals in plastics to ensure safety and environmental protection.
  • Regular evaluations - The treaty may include regular evaluations to assess progress.

Species within the Globba genus are known for their ornamental value and are often called dancing girls due to their delicate and attractive flowers.

  • Genus - Habitat- It is commonly found in tropical regions such as Southeast Asia, India, and the Eastern Himalayas.

Globba corniculata

Named for horn-shaped structure at the base of the labellum.

Found in West Bengal's Darjeeling district.

Globba paschimbengalensis

Named after West Bengal.

Globba polymorpha

Named for the variation in bracteole colour within the species population, found in West Bengal.

Globba tyrnaensis

Dancing girl ginger

  • Taxonomic collection challenges - In the northeastern States it is a significant challenge in identifying species from these sacred groves since voucher collections from these locations are prohibited.

Planetary Protection

Planetary protection ensures that Earth and other celestial bodies are shielded from cross-contamination by microbial life during space missions.

  • Planetary protection- It is the principle of preserving the biospheres of both Earth and other planetary bodies from contamination by microbial life during space missions.
  • It’s an important principle of interplanetary missions, such as from the earth to the moon or Mars.
  • The Committee on Space Research (COSPAR), Committee of the International Science Council (ISC) has formulated a planetary protection policy to guide compliance with the United Nations Outer Space Treaty.
  • The principle is grounded in Article IX of the Outer Space Treaty (1967).
  • Compliance- The spacecraft are sterilized by assembling them fully and baking them in a dry room at 120°C for 3 days to prevent contamination.
  • Application- The principle of planetary protection is applied in missions like NASA’s Viking 1 (the first spacecraft to land on Mars in 1976) and China’s upcoming Tianwen-3 Mars sample-return mission (planned for 2028).

Outer Space Treaty

  • The Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies.
  • It is a multilateral treaty that forms the basis of international space law in 1967.
  • It was adopted by the United Nations General Assembly on December 19, 1966 and entered into force on October 10, 1967.
  • It establishes rules for the peaceful use of space and prohibits the stationing of weapons of mass destruction in space.
  • The treaty also defines the rights of nations to the moon and other celestial bodies.
  • Principles
    • Peaceful use - The treaty establishes legally binding rules for the peaceful exploration and use of space.
    • No weapons of mass destruction - The treaty prohibits the stationing of weapons of mass destruction in space.
    • No military activities - The treaty prohibits military activities on celestial bodies.
    • Free exploration - The treaty declares that space is an area for free use and exploration by all.
    • Sharing of knowledge - The treaty enshrines the principle of sharing scientific findings and knowledge.
  • Members - As of June 2024, 115 countries are parties to the Outer Space Treaty (OST), and 23 more countries have signed but not yet ratified it.
  • India signed the treaty in March 1967 and ratified it in 1982.

National Clean Air Program

  • Year- 2019
  • Ministry- Ministry of Environment, Forest and Climate Change.
  • About- The program is a pollution control initiative, the government committed funds as well as set targets for 131 (non-attainment cities) of India’s most polluted cities.
  • Non-attainment cities- They are called as non-attainment cities as they did not meet the national ambient air quality standards (NAAQS) for the period of 2011-15 under the National Air Quality Monitoring Program (NAMP).
  • Goal- To meet prescribed annual average ambient air quality standards at all locations in the country in a stipulated timeframe (long-term).
  • Objectives-
    • Stringent implementation of mitigation measures for prevention, control and abatement of air pollution.
    • Augment public awareness and capacity building measures.
    • Augment and strengthen air quality monitoring network across the country
