Corals are tiny plant-like animals that depend on clean, clear waters
and sunlight to grow. These corals gradually build skeletons that shape
the reef, transforming it into an enormous structure that exists for
thousands of years. These coral reef structures – Earth’s
great underwater forests – are a key part of our planet’s
ecosystem. They nurture one-quarter of the world’s marine life,
supply hundreds of millions of humans with food and resources, harbour
potentially life-saving natural chemicals, and protect coastal communities
from damage.
But climate change, particularly global warming – the result of
the buildup of greenhouse gases like carbon dioxide (CO2) – along
with pollution, overfishing and overuse, threaten to destroy these valuable
reefs. Already, about 30 percent worldwide have been damaged – and
another 60 percent could disappear in the next quarter century unless
swift action is taken. Scientific communities and organizations around
the globe are seeking to save the reefs from further degradation, but
concerned individuals can make a big difference. Here’s
what you can do to save energy…and the reefs.
