01 · THE BIG PICTURE

A living planet under pressure

Biodiversity is the variety of life at the level of genes, species and ecosystems. Human land use, overexploitation, pollution, invasive species and climate change interact in ways that can make recovery harder. The goal of conservation is not simply to save individual animals: it is to keep ecological systems functioning.

24/7wildlife depends on functioning habitats and food webs

1planet shared by every species on this page

🌳

Habitat

Protected habitat gives populations room to feed, breed, migrate and adapt.

🌡️

Climate

Warming can shift temperature, rainfall, sea ice, wildfire and ocean conditions.

🧬

Genetic diversity

Small isolated populations can lose genetic diversity and become more vulnerable.

🕸️

Food webs

Removing one species can change predators, prey, pollination and nutrient cycles.

🚫

Illegal trade

Wildlife trafficking can remove animals faster than populations can replace them.

🤝

People

Successful conservation often combines science, local stewardship, policy and livelihoods.

“The biodiversity crisis is not a distant problem. It is a question of whether the living systems that support people and wildlife can continue to function.” Educational paraphrase based on themes in IPBES global biodiversity assessments.

03 · CLIMATE PRESSURE

A warmer world changes the rules

Climate change is not a single threat. It changes temperature, precipitation, fire weather, ocean chemistry, sea level, ice cover and the timing of biological events. Species already restricted to small habitats can have fewer places to move.

Heat

Extreme heat can push animals beyond their physiological limits and shift suitable habitat toward cooler elevations or latitudes.

Sea Ice

Arctic sea-ice decline changes hunting platforms, migration routes and seasonal access to food for ice-associated wildlife.

Ocean Warming

Marine heatwaves can disrupt food webs and drive mass mortality events in sensitive coastal ecosystems.

Coral Bleaching

When corals are stressed by unusually warm water they can expel symbiotic algae, reducing energy and increasing mortality risk.

Ocean Acidification

Absorption of carbon dioxide lowers seawater pH and reduces carbonate availability for many shell-building organisms.

Wildfire

Hotter and drier conditions can increase fire weather in some regions, transforming forests, grasslands and nesting habitat.

Drought

Longer or more intense drought can shrink wetlands, reduce forage and concentrate wildlife around fewer water sources.

Sea Level Rise

Coastal wetlands, mangroves, beaches and nesting sites can be squeezed between rising seas and developed shorelines.

Seasonal Timing

Warming can alter flowering, insect emergence, migration and breeding timing, creating mismatches across food webs.

Range Shifts

Species may move toward cooler conditions, but mountains, cities, farms and fragmented landscapes can block movement.

Disease

Climate-driven changes in temperature, rainfall and host ranges can alter the distribution and intensity of some wildlife diseases.

Food Webs

A change in one species can cascade through predators, prey, pollinators and ecosystem processes.

↗

Heat → range shift

Mountain and polar species can run out of cooler habitat when movement is blocked by geography or human development.

↗

Ocean warming → bleaching

Repeated marine heatwaves can leave coral communities less time to recover between disturbances.

↗

Drought → fragmentation

Water-dependent wildlife can become concentrated around shrinking resources, increasing competition and conflict.

↗

Fire → habitat change

Some ecosystems are fire-adapted, while others can be transformed when fire becomes more frequent or severe.

↗

CO₂ → ocean chemistry

The ocean absorbs a substantial share of human carbon dioxide emissions, changing carbonate chemistry.

↗

Timing → mismatch

If plants, insects, birds and predators respond to warming at different rates, familiar seasonal relationships can break down.

04 · WHAT WORKS

Conservation can change trajectories

Protection is most effective when it addresses the pressure actually driving decline. Different species need different combinations of habitat protection, enforcement, restoration, captive breeding, disease management, community stewardship and climate adaptation.

🛡️

Protect habitat

Create and effectively manage protected areas while maintaining ecological connectivity.

🌱

Restore ecosystems

Rebuild wetlands, forests, reefs, rivers and grasslands where recovery is feasible.

🚓

Stop illegal killing

Reduce poaching and illegal trade through enforcement, demand reduction and community action.

🎣

Make fishing safer

Reduce bycatch, improve gear and protect nursery and feeding areas.

🧬

Recover populations

Use captive breeding, translocation and genetic management when wild populations are critically small.

🗺️

Protect corridors

Connect fragmented habitats so animals can move as conditions change.

⚡

Reduce emissions

Rapidly reducing greenhouse-gas emissions lowers long-term climate risk to ecosystems.

🏘️

Support local stewards

Conservation is stronger when local and Indigenous communities have rights, resources and meaningful participation.

📡

Monitor continuously

Camera traps, acoustic sensors, genetics, satellite imagery and field surveys reveal whether interventions work.

💚

Fund the long term

Threatened species recovery often requires decades of consistent attention rather than one short project.

“In the end we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught.” Often attributed to Baba Dioum; wording appears in multiple published forms.
