Jakarta, CNBC Indonesia – Cases of great fires that occurred in various parts of the world can be seen clearly from space. This was revealed by NASA Astronaut Megan McArthur, who was aboard the International Space Station (ISS).
He emphasized that this condition is a warning to the entire global community. According to him, global community cooperation is needed to face this and overcome these challenges.
“We are very sad to see fires across large parts of the Earth, not just the United States,” said Megan McAthur in an interview with Insider and quoted from Futurism, Sunday (24/10/2021).
“For years scientists around the world have been ringing this alarm bell,” he continued.
Satellite imagery can indeed show what is happening on Earth, such as catastrophic forest fires in the form of smoke clouds of astronomical proportions in many areas of the planet. From Siberia, Greece and Spain to the Pacific Northwest.
Turkey is said to have been hardest hit this year by the case of forest fires. In fact, the United States (US) is struggling to recruit enough firefighters to tackle wildfires.
Meanwhile, the Brazilian Amazon rainforest is also now under threat due to deforestation. This has been the case for the past few decades, according to Dr. Simon Evans of Carbon Brief.
Deforestation or deforestation is carried out so that the land can be converted to other uses, such as agriculture, animal husbandry and even residential or urban areas. In Brazil, colonialist-driven deforestation to clear land for growing cash crops such as rubber, sugar and tobacco.
This was then accelerated in the last half of the 20th century to create cattle ranching, plantations for industrial-scale crops, such as soybeans, oil palm, and logging activities.
Recently, an aerial photo showed the world’s largest forest continues to experience intense land degradation. These conditions make the Amazon release more CO2 than it has absorbed in the last 10 years.
Researchers reveal that as much as 40% of the Amazon rainforest could turn into a drier savanna-like landscape if rainfall levels continue to decline as a result of climate change.
Savanna is an ecosystem that is characterized by less tree cover and is dominated by grasslands. Savannas tend to exist in temperate climates with less rainfall than rainforests require.
