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.

This quiz explores how human activities, such as poaching and overgrazing, negatively impact grassland ecosystems. Learn about the consequences of these activities on wildlife and vegetation, and the efforts being made to combat them. Understand the significance of international agreements like CITES in protecting endangered species.
