The collapse of insects
Insect decline
The global insect population is declining at an unprecedented rate.
Decline rate: up to 2% per year.
Causes: Deforestation, pesticide use, artificial light pollution, climate change.
Importance of Insects
Insects are crucial to ecosystems and human survival.
Ecosystem Role: Insects are essential for feeding birds, reptiles, and mammals, including humans.
Soil Health: Insects help churn and maintain healthy soil.
Pollination: Over 75% of global crops rely on insects, valued at $577 billion per year.
Causes of insect decline
Multiple factors contribute to the decline of insect populations.
Habitat Loss: Urbanization and agriculture reduce natural habitats.
Pesticides: Harmful chemicals in agriculture kill insects.
Climate Change: Alters ecosystems, making them uninhabitable for many insects.
Light Pollution: Disorients nocturnal insects like fireflies.
Examples of Affected Insects
Consequences of decline
The decline in insects has severe implications for ecosystems and human society.
Economic Impact: Loss of pollinators and other beneficial insects could cost billions in agriculture and environmental services.
Food Security: Reduced insect populations lead to lower crop yields.
Ecosystem Collapse: Loss of insect diversity threatens the balance of ecosystems.
Butterflies and Moths: A significant decline in populations due to habitat loss and pesticides.
Bees: 28% of North American bumblebee species are threatened.
Fireflies: Urban light pollution contributes to the decline of these insects.
