5.2.1 Global environmental problems

• What are global environmental problems?

  Issues affecting the entire planet
• Climate change is caused by greenhouse gases
• Human activities are the main causes of global environmental problems
• Match the global environmental problem with its main cause:

  Climate Change ↔️ Burning fossil fuels

  Deforestation ↔️ Clearing forests

  Pollution ↔️ Industrial processes

  Biodiversity Loss ↔️ Habitat destruction
• What are the four major global environmental problems mentioned in the text?

  Climate change, deforestation, pollution, biodiversity loss
• Burning fossil fuels increases greenhouse gases, which leads to global warming.


  True
• The major global environmental problems include climate change, deforestation, pollution, and biodiversity loss
• Rising sea levels caused by climate change can lead to the displacement of coastal populations.


  True
• What is one impact of deforestation on human societies?

  Reduced forest resources
• What is one impact of biodiversity loss on human societies?

  Disrupted livelihoods
• Reducing personal carbon footprint can be achieved through energy efficiency, renewable energy, and sustainable transportation
• What is one way individuals can support environmental protection efforts?

  Advocate for policies
• Reforestation increases carbon sequestration, habitat restoration, and biodiversity
• Reforestation increases carbon sequestration and biodiversity.


  True
• What are the three main steps involved in waste reduction?

  Reduce, reuse, recycle
• What are the three key efforts that can enhance environmental solutions?

  International cooperation, government action, individual efforts
• What is a defining characteristic of global environmental problems?

  They require international cooperation
• Climate change leads to rising sea levels and melting polar ice caps
• Deforestation results in the loss of rainforest habitats in the Amazon.


  True
• What type of pollution causes respiratory illnesses in cities?

  Air pollution
• Biodiversity loss can lead to the extinction of endangered species
• What is the primary cause of climate change?

  Greenhouse gas emissions
• What is an example of the impact of air pollution in cities?

  Respiratory illnesses
• Deforestation releases stored carbon into the atmosphere.


  True
• How do industrial processes contribute to environmental problems?

  Contaminate air, water, and soil
• Habitat destruction disrupts ecosystems and reduces biodiversity
• What are the impacts of climate change on natural ecosystems?

  Rising sea levels, melting glaciers
• Deforestation leads to soil erosion and reduced forest resources.


  True
• How does pollution affect human societies?

  Causes health issues
• Biodiversity loss reduces the ability to adapt to environmental changes
• What is the main goal of the Paris Agreement?

  Limit global temperature rise
• The United Nations Sustainable Development Goals promote environmental protection and sustainable development.


  True
• Examples of individual actions to tackle environmental problems

  1️⃣ Reduce carbon footprint

  2️⃣ Participate in local conservation

  3️⃣ Support sustainable businesses
• What are the United Nations Sustainable Development Goals adopted by UN member states designed to promote?

  Sustainable development
• The Montreal Protocol is an international agreement to phase out the production and use of ozone-depleting substances
• Reducing personal carbon footprint can be achieved through energy efficiency, renewable energy, and sustainable transportation.


  True
• What is the primary goal of the Paris Agreement?

  Limit global temperature rise
• Steps individuals can take to reduce their carbon footprint

  1️⃣ Use energy-efficient appliances

  2️⃣ Switch to renewable energy sources

  3️⃣ Use sustainable transportation options
• What temperature increase does the Paris Agreement aim to limit global warming to?

  Below 2°C
• Generating electricity from renewable sources reduces dependence on fossil fuels.
