Five good environmental stories from 2021 | Natural Issues

From the history of global warming destructive fire in Siberia in Russia, to the long-term drought that is plaguing South America and other countries the worst flooding in South Sudan in the 60’s, there have been many negative reports about the government the whole universe in 2021.

But within a year the environmental crisis – inclusive more useless Global climate talks in Glasgow, a locust-infested locust plague in East Africa, and the entire city becoming destroyed by fire in western Canada – young shoots of hope have emerged.

In terms of globalization, scientists and conservationists have highlighted five key issues for 2021:

1) Ozone layer is healing

It was one of the major developments in the 1980’s: in an effort to stave off the ozone layer, which protects the earth from harmful UV light, from developing. Protesters staged street demonstrations and politicians held large rallies.

And changes are taking place, according to the latest learning by US National Center for Atmospheric Research (NCAR): Thanks to the 1987 Montreal Protocol, a global agreement to regulate almost 100 per cent antioxidants, 443 million Americans will be rescued from skin cancer by the end of this century.

The ozone layer remains large – almost the same size North America – but it recovers at a rate of one to three per 10 years, according to the UN. The hole in the northern hemisphere is expected to fully recover by the 2030s, with a complete overhaul of the southern hemisphere and polar regions expected by the 2060s, according to UN data.

The global impact of the crisis through the Montreal Protocol has prevented more than 99 percent of the health effects that would have occurred as a result of ozone depletion, NCAR said.

Environmentalists hope that a gradual increase in ozone depletion will return coping with climate change; so far, that has not happened.

2) ‘Coral IVF’ supports Australia’s Great Barrier Reef

The world’s largest building is in danger rising sea temperatures related to climate change, which has led to coral purification.

This year, however, it has been going well Great Barrier Reef. Scientists have been using artificial insemination in a similar way to in vitro fertilization (IVF), moving eggs into coastal areas where rocks grow. These are transferred to repair areas affected by bleaching or storm damage.

The birth control method, called “coral IVF”, helped the birth of billions of new coral babies this year, in a national outbreak. The coast is still facing significant dangers, but scientists and conservationists hope that these types of technologies could be a major boost. healing from the rocks of the earth, the home of about a quarter of aquatic life.

3) China’s largest Pandas are no longer ‘in danger’

Home for over 1,800 great pandas Living in the desert, China also announced in July that well-known bears are no longer “in danger”. As a result of efforts to protect, they have now been classified as “insecure”.

The International Union for Conservation of Nature, the next independent group, created a similar monitoring several years earlier.

A little credit for directing big panda The population comes from protected areas located in the most populous country in the world, about 18 percent of China’s territories, according to Chinese officials.

4) Creating renewable energy hits all the time

Although supply chain problems from the COVID-19 epidemic, 2021 is expected to be very high in generating renewable energy.

With the new launch of solar, wind farms and other technologies, the world has added 290 gigawatts of renewable energy sources this year, according to a report. published this month and the International Energy Agency from Paris. In comparison, this is twice as much as the average electricity generation in Canada 145 gigawatts.

In light of these practices, renewable energy The potential for more than just global oil production and nuclear power by 2026. Globally, more than 90 percent of new renewable energy in the next five years is expected to come from renewable energy sources. The growth rate, however, is not too fast to achieve the goal of net-zero carbon emissions by 2050.

5) Protected areas are spreading around the Galapagos Islands

In the 19th century, the remarkable animals of the Galapagos archipelago inspired Charles Darwin to write On the Origin of Species and to establish evolution.

Last November, The President of Ecuador has announced that the protected area around the Galapagos will be expanded by 60,000sq km (37,282 sq miles).

Home to adult turtles, sea turtles, penguins, sea lions and frigatebirds, among other things, the region is at risk of climate change. illegal fish and other difficulties. Conservationists hope to expand the reserve to help preserve its natural beauty and wildlife.
