Greta Thunberg has completely taken over the world in the last few weeks.

Her face has been plastered across the front pages of newspapers and she has made headlines all around the globe.

The sixteen-year-old's commitment to helping to change to our planet in a bid to tackle climate change is truly inspiring, but this isn't the only thing that people have been talking about.

Her bravery to stand up to President Trump has been condemned around the world, and the president has been royally trolled recently by the teenager and by her supporters.

And now one of Trump's ... associates has hit back against Thunberg. And Trump's weighed in too, because of course he has.

Only those who have lived on another planet won't know who Greta Thunberg is...

The sixteen-year-old Swedish activist is the one responsible for the global school strike movement, which began with her doing solo weekly school strikes to protest for climate change action.

Over the last year, Thunberg has become one of the most famous women in the world.

After a year of protesting alone, she sat on the steps of parliament in Stockholm, holding up the famous sign that read: "Skolstrejk För Klimatet" — translating to “School Strike For Climate." By sacrificing her education to protest for action, Thunberg very quickly began to conjure up attention in the media.

Her protests have opened eyes around the world.

According to the United Nations, humanity has under twelve years to prevent a climate change crisis. A report released by the Intergovernmental Panel on Climate Change (IPCC) at the end of 2018 called for immediate “unprecedented changes" to all aspects of society.

In July, the teenager ditched air travel and sailed across the Atlantic to attend the U.N climate summits in the U.S and Chile.

She has given powerful speeches to numerous world leaders, including directly to U.S Congress in which she stated: "You must do the impossible. Because giving up can never ever be an option."

Her speech in the General Assembly of the Climate Action Summit last week caught the attention of the entire world.

The speech, which was held at the United Nations in New York City, was powerful and extremely emotional, with Thunberg saying: "I shouldn’t be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope? How dare you!" "You have stolen my dreams and my childhood with your empty words."

She didn't hold back her anger and frustration...

“People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction. And all you can talk about is money and fairy tales of eternal economic growth. How dare you!," she went on to say.

Thunberg is desperately trying to make the world realize the danger that our planet is in...

“We will not let you get away with this. Right here, right now is where we draw the line. The world is waking up. And change is coming, whether you like it or not," she said in the desperation.

During her visit to the United Nations, she crossed paths with President Donald Trump in the lobby.

Of course, Thunberg isn't Donald Trump's biggest fan, purely because of the fact that the president refuses to acknowledge climate change and has even claimed that the whole thing is a myth. "I don't believe it," he said according to the BBC. "Right now we're at the cleanest we've ever been and that's very important to me."

Thunberg's "death stare" was caught on camera and it very quickly went viral...

The fact that she was facing one of the world's most powerful leaders and she refused to hide her feelings is a totally heroic move.

But, of course, President Trump very quickly got wind of Thunberg's opinions.

He was quick to comment on the courageous teenager, saying in a sarcastic tweet: "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"

His petty swipe at Thunberg caused a lot of anger...

Hundreds of thousands of people took to social media to bash the president for "bullying" a teenage girl. One user on Twitter wrote: "The President of the United States making a sarcastic, snide comment to make fun of a 16-year-old passionate about fighting climate change is a new low for Trump. Disgusting."

Many weren't sure of how Thunberg would react to this trolling by the President of the United States...

Her mental health has been a consistent worry of many during her time as an activist over the last year. She rose to fame extremely quickly, with her now having 7.1 million followers on Instagram. Thunberg is a young woman who has a history of depression, OCD, anorexia, was a selective mute for several years, and has been diagnosed with Aspergers Syndrome.

But despite many worrying that she will soon "burn out" or have a breakdown...

Her following and support system is larger than ever, and she recently showed President Trump that he doesn't intimidate or scare her.

Thunberg recently updated the bio of her Twitter account...

"A very happy young girl looking forward to a bright and wonderful future," her new bio reads, which is a clear dig at the president, showing that Thunberg isn't going to let his childish and petty online comments stop her from doing what she believes is right.

Thunberg's bio caused an avalanche of support...

But it also spurred on an avalanche of trolls against the president, with users calling him out for being outdone by a teenager.

The trolling didn't end there...

It has been taken to another level completely with a brand on Etsy creating red caps that resemble the ones that read "Make America Great Again," but, instead, they read "Make America Greta Again."

The Greta baseball caps are made with a good cause in mind...

Etsy shop owner, Johnathan Hansson, is selling his handmade baseball caps for twenty-nine dollars (299 Swedish Krona), and he has claimed that 100% of the profits will go towards Greenpeace.

The product is a clear sign of support towards Thunberg...

In the description, he wrote: "The little girl with the big heart vs. The big boy with the little brain." 100% of the profits from this cap goes to Greenpeace and their work to save the planet. Available in two sizes with an elastic stretch band, this hat is a sure winner in comfort - it has an athletic shape with a curved visor, too!

It's looking like the custom hats will be a huge success...

They have gone down an absolute treat with Thunberg's supporters and those who are against President Trump, and it seems to be a slight coincidence that all of the drama has come about amidst rumors of the president's impeachment.

It's clear who the real winner is here...

Thunberg is actually working towards a cause that matters, and a cause that will positively impact so many people around the world, and it's safe to say that President Trump isn't doing the same.

And now another big name has spoken out against Thunberg.

Vladimir Putin has taken aim at the teenage activist, claiming that she doesn't know what she's talking about, and may be being used by the adults around her.

He spoke out at the Energy Partnership for Sustainable Growth.

"I may disappoint you but I don't share the common excitement about the speech by Greta Thunberg."

"No one has explained to Greta that the modern world is complex and different."

"People in Africa or in many Asian countries want to live at the same wealth level as in Sweden."

"Go and explain to developing countries why they should continue living in poverty and not be like Sweden."

And that's not all Putin criticized her for. He also claimed that she may be being used by the adults around her. "When someone is using children and teenagers in personal interests, it only deserves to be condemned."

"I'm sure that Greta is a kind and very sincere girl."

"But adults must do everything not to bring teenagers and children into some extreme situations."

And now Trump's pitched in too, because of course he has.

Supporting people who hate on a sixteen-year-old girl? Nice, Mr. President. We hope that Thunberg doesn't let the haters get her down - because she has one very famous fan. Curious? Read on.
