one Hole Reduced: In 2006, the hole was 10.3 million square miles. However, recently it has reduced to 3.6 million square miles. Scientists say that the hole is smaller than it was found in 1985. Deep Carbon Observatory: Deep Carbon Observatory (DCO) is a global research program to outreach carbons role on Earth. It has found that there are ultra – deep diamonds at 670 km depth in the mantle. It has signatures of geochemical signature of organic material from Earth’s surface. There may be significant amounts of iron carbide in the Earth’s core that accounts to two – thirds of Earth’s carbon.
Eco-friendly Crackers
The regular crackers release Barium Nitrate the main pollutant. It is now replaced with Potassium Nitrate. Also, crackers pollute the environment by leaving dangerous toxins, metal particles, smoke and harmful chemicals.
Also, the court restricted the time of bursting crackers between 8 pm and 10 pm.
SC also encouraged use of green crackers and improved crackers. Improved crackers are those which use ash as filler and reduces the particulate emission by 15 to 20%.
Green Crackers are those that reduces emission of Nitrogen dioxide and sulfur dioxide and reduces the overall harmful particulate emissions by 30 to 35%.
