Droughts

Do you know what a drought is? If you don’t, keep reading to find out.

Silk Road #12

This is what soil looks like in an area that is suffering severe drought.

A drought is a long period of time when there is a water shortage and it has barely rained. This is bad because it can cause crop loss which is when it is so hot that crops wilt. When crops wilt we also have food shortage.

What causes drought?

  • Greenhouse gases cause drought.  How? When people use fossil fuels, it lets of greenhouse gases which stay in Earth’s atmosphere and cause heat
  • Global warming and climate change. How? Another cause of drought is global warming and climate change because as years pass it keeps getting hotter and hotter and heat causes water to evaporate
  • Us! How?  You are probably thinking, Us? How did us humans cause drought?  We humans cause drought by wasting water. Sometimes it’s when leave the sink on while we’re brushing are teeth. Sometimes it’s when you flush the toilet when it is not necessary.

But the people who caused it can also help. We can conserve(save) water. Don’t keep the sink on when you’re brushing your teeth. Be extra careful that you don’t flush the toilet by accident.

Remember to take your part and take drought down!

Harlequin Bugs

Harlequin bug

Nymph harlequin bug

When we went to Rose Canyon our nice tour guides showed us the Harlequin bug. These bugs are very fascinating and smart at the same time. The Harlequin bug is part of the Pentatomidae species but the scientific name for the Harlequin bug is Mugantia Pentatomidae. They are very annoying around veggies such as radishes ,broccoli , and an oriental flower called the Cleome. The harlequin bug is actually a beetle because every beetle a a line down their back that kinda makes the shape of a triangle. A Harlequin bug’s way of defense is falling down. That way predators won’t get to touch it, grab it ,or eat it. Baby Harlequin  bugs can be as small as two centimeters but the biggest  Harlequin bug that we saw was about half an inch. Some people in our class went there last year and they saw 2 harlequins bugs mating together to produce offspring. I really saw that the development of the Harlequin bugs have increased with more nymphs and adults since last year. Harlequin bugs are NOT poisoness  the are NOT harmful either so if you see one don’t worry. Harlequin bugs are fascinating bugs to learn about and to observe in real life .
