From new protected areas to ozone layer gains, this year saw some positive trends, even as myriad problems persist.

readersupported news.org From record heatwaves causing devastating wildfires in Russia’s Siberia, to a prolonged drought hitting South America and the worst floods to hit South Sudan in 60 years, there has been plenty of bad news when it comes to the state of the global environment in 2021.
But amid a year of worsening environmental stress – including mostly ineffective international climate negotiations in Glasgow, locust plagues ravaging crops in East Africa, and an entire town being destroyed by fire in western Canada – some small shoots of hope have emerged.
When it comes to the state of planet Earth, scientists and
conservationists have highlighted five of the most important good-news
stories from 2021:
1) The ozone layer is healing
It was one of the key environmental causes of the 1980s: trying to
prevent the hole in the ozone layer, which protects the planet from
harmful UV rays, from getting any larger. Activists mobilised street
protests and politicians held summits.
And change is happening, according to a recent study
by the US National Center for Atmospheric Research (NCAR): Because of
the 1987 Montreal Protocol, a global deal to regulate nearly 100
man-made chemicals that deplete the ozone layer, 443 million Americans
will likely be spared from skin cancer through the end of this century.
The hole in the ozone layer remains enormous – about the size of North America – but it is recovering at a rate of one to three percent every 10 years, according to the UN.
The hole over parts of the northern hemisphere is expected to heal
completely by the 2030s, with full repair over the southern hemisphere
and polar regions expected by the 2060s, according to UN data.
Global action on the problem via the Montreal Protocol has prevented
more than 99 percent of potential health effects that would have
otherwise occurred from ozone destruction, NCAR reported.
Environmentalists hope the relative success in the movement to protect the ozone layer can be replicated in the fight against climate change; so far, that has not happened.
2) ‘Coral IVF’ aids Australia’s Great Barrier Reef
The world’s largest living structure is under threat from rising ocean temperatures linked to climate change, which have caused coral bleaching.
This year, however, has seen some recovery on the Great Barrier Reef.
Scientists have been using man-made pools in a process comparable to in
vitro fertilisation (IVF), moving eggs from areas of the reef where
coral has been growing. These are then transferred in an effort to
regenerate areas hit by bleaching or destruction from storms.
The process of assisted spawning, dubbed “coral IVF”, aided the birth
of billions of new coral babies this year, in an explosion of colour.
The reef is still facing substantial dangers, but scientists and
conservationists hope these types of technologies can spur broader recovery in the world’s reefs, home to roughly a quarter of marine life.
3) China’s giant pandas no longer ‘endangered’
Home to more than 1,800 giant pandas
living in the wilderness, China reported in July that the iconic bears
are no longer officially “endangered”. Thanks to conservation efforts,
they are now classified as just “vulnerable”.
The International Union for Conservation of Nature, an independent tracking group, made a similar assessment several years earlier.
Partial credit for the improvement in the giant panda
population can be traced to an expanded network of protected areas in
the world’s most populous country, covering about 18 percent of China’s
landmass, according to Chinese authorities.
4) Renewable energy generation hits all-time high
Despite supply chain problems stemming from the COVID-19 pandemic, 2021 was expected to set an all-time high for new renewable energy production capacity.
With new solar installations, wind farms and other technologies, the
world added 290 gigawatts of renewable power production capacity this
year, according to a report published this month
by the Paris-based International Energy Agency. By comparison, that is
twice as much as Canada’s total electricity generating capacity of about
145 gigawatts.
Based on these trends, renewable energy
capacity could exceed the current global capacity of fossil fuels and
nuclear energy combined by 2026. Globally, more than 90 percent of new
electricity generating capacity in the next five years is projected to
come from renewables. The pace of growth, however, is still not fast
enough to reach the goal of net-zero carbon emissions by 2050.
5) Protected area expands around Galapagos Islands
In the 19th century, amazing animal life on the remote Galapagos
Islands inspired Charles Darwin to pen On the Origin of Species and
pioneer the theory of evolution.
This past November, Ecuador’s president announced that a marine-protected area around the Galapagos would be expanded by 60,000sq km (37,282 sq miles).
Home to giant tortoises, marine iguanas, penguins, sea lions and
frigatebirds, among other species, the area is under threat from climate
change, illegal fishing
and other challenges. Environmentalists hope expanding the protected
area will help preserve its unique natural beauty and wildlife.
Good news on the environment front is scarce, but let's pause to recognize a few victories achieved in 2021.
