What human activity replaces marine habitats with buildings, roads, and infrastructure?

Coastal Development

100

These underwater ecosystems support species like clownfish, parrotfish, and sea turtles but are heavily damaged by coral bleaching.

Coral Reefs

100

This happens to many marine species when they are forced to move to cooler or safer waters because of climate change.

Forced migration

100

This phenomenon happens when corals lose their color due to stress from rising ocean temperatures.

Coral Bleaching

200

What type of pollution causes algal blooms and lowers oxygen levels in the water?

Nutrient runoff pollution

200

These coastal habitats act as nurseries for fish, crabs, shrimp, and juvenile sharks.

Mangroves

200

These large marine mammals and predators are struggling to hunt because melting sea ice is destroying their habitat.

Polar Bears

200

According to studies, this famous reef system experienced severe bleaching, with about 44% of bleached corals dying.

Great Barrier Reef

300

This climate-related process happens when oceans absorb excess carbon dioxide, making it harder for coral reefs to form.

Ocean Acidification

300

These underwater forests support sea otters and many marine food webs but are declining because of warming waters.

Healthy marine ecosystems protect coastlines from these two natural dangers.

Storms and Erosion

300

This global environmental issue is the main cause of rising ocean temperatures and increasing coral reef damage worldwide.
