Hi Khairulfajri,
The photo of the cactus you have shown is called the "prickly pear". Many Mexicans eat the inside of the leaves mixed with scrambled eggs. Yes, they are very nutritious. May I suggest something to you? If you will sign up with grammarly (free version), the program will help you correct your grammar mistakes. Even a native speaker like myself uses grammarly to correct my misspelled words, grammar, word choice etc. I enjoyed your article and photos.
Thanks,
Carol
