A study of Australian teens' Instagram (a popular photo social media platform) usage found 57% of Australian teenagers use it, while 30% reported being contacted by a stranger, and 20% reported being sent inappropriate unwanted content.

Facebook is considering launching a version of Instagram for children under the age of 13 to safely use it. Currently the company does not allow people who are under 13 to create an account on the platform. A spokesperson for Facebook, announced the company was exploring a parent-controlled version, similar to the Messenger Kids app that is for kids between 6 and 12.

"Increasingly kids are asking their parents if they can join apps that help them keep up with their friends. Right now there aren't many options for parents, so we're working on building additional products that are suitable for kids, managed by parents," the spokesperson said. "We're exploring bringing a parent-controlled experience to Instagram to help kids keep up with their friends, discover new hobbies and interests, and more."

In a blog post, the company noted that although people were asked to enter their ages when signing up for Instagram, there was nothing to prevent them from lying about their ages at registration. Facebook said it would overcome that by using machine learning in association with the registration age to determine people's ages on the platform.

The company also announced plans to roll out new safety features, including preventing adults from messaging children under 13, sending safety notices to children when they are messaged by an adult who sends a lot of friend requests, and making it more difficult for adults to find and follow children using the search function in Instagram. Children will also be encouraged to keep their profiles private at the point of registration.

"My ocean is my life. "These are the powerful words of Andre Miller, a marine (海洋的) scientist. He is also the owner of a dive shop that places heavy upon the exploration and conservation of his hometown's waters.

As a young child, Andre would be fascinated by tales of the sea told by his dad who was a fisherman. When he was six years old, his mum gave him his first equipment of diving. Then, Andre spent his time diving. Andre interned (实习) at a dive shop. With this training, the young diver was able to see new depths. But unfortunately，he saw much damage.

After finishing his studies in marine biology, Andre got to work as a member of the Coastal Zone Management Unit. It was here that once again he was horrified by the rapid decline of the numbers of sea creatures and the negative effects of poor boating practices which caused havoc to the island's coral(珊瑚). Therefore, the first mission of Andre's team was to repair destroyed reefs and save coral. And they have been very successful in their efforts.

One of Andre's perfect moments was his role in the creation of the Carlisle Bay Marine Park. The park has now become the premier dive site in his hometown. Andre describes it as"the best textbook example of how marine parks can benefit the islands".

In 2016, Andre further promised his support of the conservation of Carlisle Bay through his work with other projects. Through their work, Andre's hometown has seen an increase in underwater clean-ups, which has made marine life increase greatly. Andre's contagious (有感染力的) passion for marine conservation doesn't end here. He is always searching for more. Andre Miller is a man on a mission.

I'm an 18-year-old pre-medical student, tall nd good-looking, with two short story books and quite a number of essays my credit. Why am I singing such praises of myself? Just to explain that he attainment of self-pride comes from a great deal of self-love, and to attain it, one must first learn to accept oneself as one is. That was where my struggle began.

Born and raised in Africa，I had always taken my African origin as burden. My self-dislike was further fueled when my family had to relocate to Norway, where I attended a high school. Compared to all the white girls around me, with their golden hair and delicate lips, I ,a black girl, had curly hair and full, red lips. My nose often had a thin sheet of sweat on it, whatever the weather was. I just wanted to bury myself in my shell crying "I'm so different!"

What also contributed to my self-dislike was my occasional stuttering (口吃), which had weakened my self-confidence. It always stood between me and any fine opportunity. I'd taken it as an excuse to avoid any public speaking sessions, and unknowingly let it rule over me.

Fortunately, as I grew older, there came a turning point. One day a white girl caught my eye on the school bus when she suddenly turned back. To my astonishment, she had a thin sheet of sweat on her nose too, and it was in November! "Wow," I whispered to myself, "this isn't a genetic(遗传的) disorder after all. It's perfectly normal. " Days later, my life took an-other twist(转折). Searching the internet for stuttering cures, I accidentally learned that such famous people as Isaac Newton and Winston Churchill also stuttered. I was greatly relieved and then an idea suddenly hit me—if I'm smart, I shouldn't allow my stuttering to stand between me and my success.

Another boost to my self-confidence came days later as I was watching the news about Oprah Winfrey, the famous talkshow host and writer—she's black too! Whenever I think of her story and my former dislike of my color, I'm practically filled with shame.

Today, I've grown to accept what I am with pride; it simply gives me feeling of uniqueness. The idea of self-love has taken on a whole new meaning for me: there's always something fantastic about us, and what w need to do is learn to appreciate it.
