Today marks 50 years of Earth Day, Google dedicates its doodle to 'Bee'

On the 50th anniversary of Earth Day, Google has dedicated its doodle to bees, the smallest and most important creature on Earth. It was first celebrated in the year 1970.

Earth Day is an annual event which is celebrated across the world today i.e. on 22 April for environmental protection. It was first celebrated in the year 1970. This year marks 50 years of Earth Day where its theme 'Climate Action' has been kept. "Earth Day or Earth Day" is observed to protect the environment. This movement was given this name by Julian König in 1969. With this, the 22nd of April was chosen to celebrate it.


Today, on the 50th anniversary of Earth Day, Google has dedicated its doodle to bees, the smallest and most important creature on Earth. The doodle also has a bee with a "play" option button. As soon as users click on it, a short video will play which highlights the importance of bees as they contribute two-thirds of the world's crops through the method of pollination.


Apart from this, there is also a small game in which users can learn fun facts about bees and our planet how bees sit on flowers and carry life forward.



The doodle has been created with the hope that people all over the world understand the importance of bees on the earth and humanity.

World Earth Day: Lockdown done by the governments which were not able to do in years

Nature has also benefitted from the lockdown implemented to prevent the spread of the epidemic. During this period, pollution on the earth has come down due to stagnation of work in industries, ban on movement of vehicles and halt construction work. Experts believe that lockdown has done what governments could not do in years to purify air and water.

1. Increased oxygen content in the Ganges

Pollution in rivers has reduced considerably due to the shutdown of industries. Ganga and Yamuna water among the most polluted rivers have also been cleaned. The amount of dissolved oxygen in the Ganges water has increased by more than one percent in Rishikesh and Haridwar in Uttarakhand. According to the Central Water Commission, the standard for the amount of dissolved oxygen in river water is 6.00 per liter. In Rishikesh, there is a big difference between the samples taken on March 24 before lockdown and April 18 during lockdown. Earlier, the amount of oxygen in Ganga was 5.20 per liter, which has increased to 6.50 per liter. On the other hand, the quantity of dissolved oxygen in the Ganges in Haridwar was earlier 4.50 per liter, which has now reached 5.75 per liter. This is slightly lower than the standard.

This will be beneficial: Professor Dayashankar Dixit, spokesperson of chemistry at Government Degree College, Rishikesh, said that due to clearing of water, the number of water creatures in the Ganges will increase. The number of Mahaseer, golden fishes that purify the water in the Ganges will also increase.

Yamuna better than before: Due to the lockdown, however, Yamuna water in Delhi has not been able to be washed. But it is definitely better than before. This has improved with the release of more water from the Palla barrage and the closure of factories.

2. The air is breathable

With the ban on vehicular movement and construction during the bandh, the air of the entire country including Delhi-NCR has become breathable. The atmosphere has become so clear that the hills of Himachal, 200 km from Jalandhar, were also visible. Delhi's average air quality index (AQI) stood at 122 points on 24 March, the day the lockdown was announced, dropping to 87 on 21 April during the lockdown.

AQI satisfactory in Ghaziabad: AQI stood at 237 on 22 March in Ghaziabad, one of the most polluted districts in the country. On 21 April, it was reduced by 135 points to 102. Earlier during the lockdown, it was 56 on 31 March and 54 on 7 April.

WHAT IS STANDARD: AQIs ranging from 0 to 50 are considered good, up to 50-100 are satisfactory. Thus the air of Delhi and Ghaziabad has remained in satisfactory category for most of the time at the time of lockdown.

3. Improvement in the ozone layer: 

There has been a lot of improvement in the ozone layer due to the shutdown of industrial activities in many big countries of the world. According to research published in the journal Nature, a reduction in the emission of chemical gases that damage the ozone layer has been made possible. It also has an effect in the atmosphere above Antarctica. The vortex formed in the atmosphere has also started coming to the right place. Scientists believe that there will be good chances in the cycle of rainfall.

 

Why is it important

The first layer of the atmosphere does not allow the ozone ultraviolet rays found just above the troposphere to reach the Earth. These ultraviolet rays cause great damage to our eyes and skin. It can cause cancer.

4. Decreased Earth's vibration

During the lockdown, the vibration in the earth has reduced by 30 to 50 percent due to the significantly reduced functioning of factories including road transport, train operations in the world. Belgian seismologists Thomas Laycock and Stefan Hicks believe this has been made possible by the reduced noise pollution. According to both, during the lockdown their instruments are now easily recording every movement in the earth during the day.
