What is a carbon footprint?
What is a carbon footprint?
The total amount of greenhouse gases released into the atmosphere as a result of human activities.
What are greenhouse gases?
What are greenhouse gases?
Greenhouse gases, like carbon dioxide (CO2) and methane (CH4), trap heat in the atmosphere, causing the Earth's temperature to rise.
Why are airplanes carbon-intensive?
Why are airplanes carbon-intensive?
Flying airplanes, especially during takeoff and landing, releases a lot of greenhouse gases because they require significant amounts of energy.

Study Notes
Human Impacts on Grasslands
- Grasslands are home to diverse plants and animals, but human activities negatively affect these ecosystems.
- Human activities harm wildlife, vegetation, and the natural balance.
- Poaching is the illegal hunting for valuable animal parts (e.g., fur, tusks, horns).
- Poaching targets "big-ticket animals" due to high market value.
- African elephants had about 1.3 million individuals in 1979, decreasing to 600,000 by 1988 due to extensive poaching for ivory.
- Poaching has been addressed with international agreements like CITES (Convention on International Trade in Endangered Species) banning ivory trade.
- The African Elephant Conservation Act (1988) further restricted ivory trade.
- Rhino horn has become a high-value commodity, causing a major decline.
- Rhino horn's value surpassed that of gold by 2012.
- Overgrazing (overfeeding by livestock) damages grasslands.
- Excessive grazing leaves land vulnerable, reducing vegetation and causing erosion.
- Overgrazing can transform fertile grassland into desert(desertification).
Human Effects on Tundra Environments
- Tundras are fragile ecosystems in Arctic and high-altitude regions.
- These ecosystems are very vulnerable to human activities and climate change.
- Human activities often lead to environmental damage and ecological disruptions in tundras.
- Industrial development (e.g., pipelines) damages habitats and disrupt wildlife movement.
- Global warming, caused by human actions, leads to higher sea levels and harms Arctic species.
- Greenhouse gases (produced via fossil fuel use, driving, deforestation, and livestock) trap heat in the atmosphere.
- Rising sea levels and melting ice caps (Arctic) threaten coastal communities.
