i'm not fasting, and i made a quiz.

hi blogosphere. how are things? i'm busy like the bees, Ramadan's over and I'm 24 now (i know, i know, old lady) and super-busy. our trip to Spain for mine and my grandmother's birthdays (we share one) was amazing, i'm still dreaming about gelato. i just finished a 2 day HIV/AIDs training, so i can more confidently incorporate AIDS education in my work. i've also been working on the tree nursery competition, since my regional co-coordinator and i were in the same place at the same time (a rare occurrence). i made a little quiz for the teachers, to give their students and get incorporate into their lessons about the importance of trees. i know america doesn't have the same tree crisis as over here, but i think the quiz is pretty interesting (probably cuz i made it), and it might even inspire some of you to go out there and plant trees (or at least do some recycling!) anyways, here it is, questions first, answers second so don't scroll down and cheat!

ANSWERS:
1.C.
One tree produces 117 kg of oxygen per year, the oxygen that we breathe every day. Trees produce oxygen as a byproduct of photosynthesis, a process by which they take in carbon dioxide and sunlight and use it to create their food (carbohydrates), than release oxygen as a byproduct.
2.B.
Less than one hectare of trees can remove up to 2.6 tons of carbon dioxide from the air every year! Because carbon dioxide is a greenhouse gas, this means that trees are a major weapon against global climate change.
3.A.
The scientific process of dendrochronology allows scientists to date trees by analyzing the rings seen in the cross-section of a tree’s trunk. A tree usually adds a ring per year, unless the weather that year is irregular.
4.D.
Trees are able to store more carbon as they age, and they store the most after they have been living for ten years. Trees also remove other pollutants from the air, such as ozone (another greenhouse gas) and sulfur dioxide, and nitrogen oxides.
5.D.
Trees are habitats for many different species of animals, and provide building materials for the homes of most humans. Trees even provide homes or shelter for marine animals, such as oysters that live on tree roots or fish that lay eggs there. Trees also provide fruits to flavor our sauces, and feed us, such as baobab and their leaves feed many mammals we live with, such as goats.
6.C.
Deforestation is a serious threat to the health of our environment. At least 12 million hectares of trees are lost every year, and the trees cut down are often not replanted, leaving animals homeless and releasing tons of carbon back into the atmosphere.
7.C.
Not only do trees clean up the air and provide homes for wildlife, they also preserve the land around them. They provide stability with their root systems that keeps soil in place, and they create natural windbreaks that prevent topsoil from being blown away.
8.A.
Only one out of every 28 trees cut down is replanted. This means that out of 100 trees cut down, only three or four new trees are planted. Make it your goal to replace EVERY tree you cut down. Trees are one of the cheapest, easiest ways to clean up our environment.
9.D.
West Africa (including the Gambia) is one of the most severely affected areas of the world. Over 90% of West Africa’s forest cover has been lost over the past century, robbing them of all the benefits of trees. Desertification, the degradation of land in climates such as West Africa has, is accelerated by loss of trees like this.
10.D.
Gambians use trees for many things, such as medicine, shade on hot days, bush tea, flavoring sauces, building houses, cooking, selling fruits to supplement income, fencing fields, and many other things. Can you think of a way not listed here that you and your family use trees?

if i were an 8th grader, this quiz would make me plant a tree. just saying.
love everybody!
