Earth and climate change questions
- 2022’s average annual temperature was 55.9F (13.3C). That’s an increase of 4.3F (2.4C). It’s important to know that 2022 was not the hottest year on record and that while just a few degrees doesn’t seem like a big deal because it’s not a big number – it’s totally still a big deal. Just a few degrees of change can shift weather patterns and play major affects on droughts, flooding, etc. as well as be detrimental to the food chain as crops and animals struggle with the change.
- Every 3 months enough aluminum goes into American landfills to create the entire US commercial air fleet. That’s nearly 6000 planes!
- Each day, about 27,000 trees are cut down. While deforestation is obviously bad, the good news is that tree-based paper can be recycled 6 times! In conclusion, you should be recycling whenever you can bestie.
- The ozone layer should be back to where it was in 1980 in just 16 years! If you feel like you remember people always talking about that ozone hole when you were little, but you haven’t heard about it in a hot sec – there’s a reason for that. Policies have helped to limit the bad stuff that was creating the hole and it’s healing itself. Although that ozone layer is still 24.5 million square kilometers (almost 9.5 million square miles), it will be healed to where it was in 1980 in our lifetimes (as long as current policies stay as they are…)!
- Germany recycles 56.1% of all waste in the country, making it the best total recycling rate in the world. After that, the next best recycling countries are Austria (53.8%), South Korea (53.7%), Wales (52.2%), and Switzerland (49.7%). For comparison, the countries with the worst recycling rates are Chile (<1%), Turkey (1%), Mexico (5%), Greece (19%), and Israel (19%).
Earth Day history questions
- Wisconsin Senator Gaylord Nelson founded the Earth Day holiday after witnessing a huge oil spill in Santa Barbara in 1969. That first year 20 million Americans (roughly 10% of the population) participated. After that, the holiday led to the creations of the NOAA and the EPA in the US – organizations that work to help our planet.
- The Earth Day theme for 2023 is Invest in Our Planet. Some other previous themes include Restore Our Earth, Mobilize the Earth, and End Plastic Pollution.
- While Earth Day spread globally in 1990, the United Nations General Assembly officially adopted it in 2009, giving it the new name of International Mother Earth Day.
- The official date for Earth Day was chosen so that the day would appeal to college students! Organizers wanted students to have the time to pay attention to the holiday, knowing that the college student population plays a huge part in activism and protests. Because of this, April 22 was chosen so that it would fall after spring break, but before finals week.
- The flag in the top left is the flag of Sierra Leone. The flag on the top right is the flag of Brazil. The flag on the bottom left is the Earth Day flag. The flag on the bottom right we just completely made up.
So, how did you do? Get them all right? Totally flunk it? Don’t feel too bad about missing some – at least this grade isn’t going to affect your gpa!
