⚖️ Negative vs Positive Human Impacts on Biodiversity

Painted 5-method conservation grid: (1) tree planting hands in fresh soil, (2) National Park entrance with wildlife, (3) breeding programmes (pandas), (4) sustainable patchwork farming with wildflowers, (5) recycling bins (plastic, paper, glass). Parchment scroll at bottom:

Figure 2: Humans both damage and protect biodiversity — the balance determines whether species survive.

Negative Impact Positive Response / Conservation
Deforestation destroys habitats Reforestation — planting trees to restore forest habitats
Hunting and habitat loss threaten animal species Captive breeding programmes for endangered species
Rare habitats built over or farmed Sites of Special Scientific Interest (SSSIs), national parks, nature reserves
Intensive farming removes field boundaries Hedgerow restoration and field margin schemes
Plant species threatened by habitat change Seed banks — frozen collections of seeds for future use
Waste pollutes land and water Recycling programmes reduce landfill and pollution

Quick Recall Flashcards

What is eutrophication and what causes it?
Eutrophication is when excess nutrients (from fertiliser or sewage run-off) enter water. This causes rapid algae growth, blocking sunlight to underwater plants. When algae die and decompose, oxygen is used up, killing aquatic organisms.
What is biodiversity?
The variety of all different species of organisms on Earth, or within a particular ecosystem. Includes the range of different habitats and genetic variation within species.
