Explore Earth's Ecosystems
Understand their beauty, balance, and the urgency to protect them.
What Is an Ecosystem?
Ecosystems can be vast, like a desert or an ocean, or small, like a pond or a fallen log. Each component plays a role, from the smallest bacteria breaking down organic matter to the largest predators maintaining population balance. They provide essential services like clean air and water, pollination, and climate regulation.
For example, in a coral reef, the corals provide structure, algae provide food through photosynthesis, fish graze on algae and are prey for larger fish, and the water provides nutrients and a medium for life.
Ecosystems are intricate networks of life and environment in balance.
The Web of Life: Interdependence
Damage to one ecosystem can have cascading effects across the globe. Understanding these connections highlights the need for holistic conservation efforts.
Forests & Rainfall
Tropical forests influence regional and even global rainfall patterns, crucial for agriculture far beyond their borders.
Oceans & Climate
Ocean currents like the Gulf Stream regulate temperatures, making distant lands habitable. Oceans absorb vast amounts of CO2.
Wetlands & Water Quality
Wetlands act as natural filters, purifying water that flows into rivers and seas, benefiting downstream ecosystems and human water sources.
The health of local ecosystems contributes to the overall well-being of our planet.

Global Threats to Ecosystems
Driven by greenhouse gas emissions, causing rising temperatures, sea-level rise, and extreme weather, impacting all ecosystems.
Clearing forests for agriculture, urbanization, and logging, leading to biodiversity loss and reduced carbon sequestration.
Contamination of air, water, and soil by plastics, chemicals, and industrial waste, harming wildlife and human health.
The decline in the variety of life forms within an ecosystem, often driven by habitat destruction, climate change, and overexploitation.
