 Theme of Earth Day 2020

On Earth Day, April 22, 2020, the world is facing two crises: One is the COVID-19 coronavirus pandemic and another one is climatic conditions. Climate Action is the theme for Earth Day 2020.  Climate change is the greatest threat to the survival of mankind and the life-sustaining structures that make our planet habitable.

Though the world was not prepared for the Novel coronavirus attack but to fight with climate crisis we still have time. We can, will and must solve both challenges. The outbreak of coronavirus has reminded us to improve our earth and address our climate crisis otherwise our current situation will become a new normal — a world where pandemics and extreme weather events cover the globe.

If we want to bring change in climate and want to save our mother earth, every individual follows some tips to save the environment.

1. Use environmentally-friendly, non-toxic cleaning products.
2. Replace inefficient incandescent light bulbs with efficient CFLs or LEDs. Reduce your carbon footprint by 450 pounds a year.
3. Carpool, ride your bike, use public transportation or drive an electric or hybrid car. Reduce your carbon footprint by one pound for every mile you do not drive.
4. Keep your tires properly inflated and get better gas mileage. Reduce your carbon footprint 20 pounds for each gallon of gas saved.
5. Change your car’s air filter regularly.
6. Teleconference instead of traveling. If you fly five times per year, those trips are likely to account for 75% of your personal carbon footprint.
7. Stop using disposable plastics, especially single-use plastics like bottles, bags, and straws.
8. Recycle paper, plastic, and glass. Reduce your garbage by 10% and your carbon footprint by 1,200 pounds a year.
9. Donate your old clothes and home goods instead of throwing them out. When you need something, consider buying used items.
10. Use cloth towels instead of paper ones.
11. Change your paper bills to online billing. You’ll be saving trees and the fuel it takes to deliver your bills by truck.
12. Read documents online instead of printing them.
13. When you need to use paper, make sure it’s 100% post-consumer recycled paper.
14. Set your office printer to print two-sided.
15. Collect used printer, fax, and copier cartridges to recycle.
16. Convince your school district or office building to choose reusable utensils, trays, and dishes in the cafeteria.
17. Use reusable bottles for water, and reusable mugs for coffee.
18. Bring reusable bags when you shop.
19. Pack your lunch in a reusable bag.
20. Organize to have healthy, locally-sourced food served at in your school district.
21. Buy local food to reduce the distance from farm to fork. Buy straight from the farm, frequent your local farmers’ market, or join a local food co-op.
22. Buy organic food to keep your body and the environment free of toxic pesticides. Support farmers and companies who use organic ingredients.

Christina blasts off to ISS on 14^th March 2019 and after 328 days she returned to the Earth. “I am so overwhelmed and happy right now,” Koch said just after she slid out from the spacecraft. she orbited Earth 5,248 times, travelling 139 million miles, roughly the equivalent of 291 trips to the Moon and back. She conducted and supported more than 210 investigations, and perhaps most importantly, participated as a research subject. Her record-breaking will help NASA to determine the long term effect of space on a human body. Christina shared her experience on its official tweeter handle “This journey has been everyone’s journey. Thank you to all involved in the success of our mission, and for giving me the opportunity to carry everyone’s dreams into space. I’m filled with gratitude to be back on the planet!”

What is Lunar Eclipse?

Lunar Eclipse occurs when Earth, Sun and Moon are aligned perfectly. This results in casting a shadow of Earth on Moon. The region where the Earth shadow is darkest is called Umbra and the region where the shadow of the Earth is partially dark is called Penumbra.

When Moon fully falls into the Umbra region where Earth’s shadow is darkest then it is called the full lunar eclipse and when Moon falls into the Penumbra where the shadow of Earth is partially dark then it is called partial lunar eclipse.

Why it is a Special Lunar Eclipse?

According to Indian Mythology, This lunar eclipse is going to occur on Guru Purnima which is occurring after 149 years that makes it a special lunar eclipse.
