1 . How to Spread Awareness About Climate Change

Climate change is one of the biggest problems we’re facing on our planet. Even though some people aren’t aware of how seriously it affects the world, there are a lot of things you can do to keep them informed.

Share news on social media.     1    . Look online for videos, news articles, and recent research about climate change from sources you trust, such as the EPA, the NOAA, or NASA. Post the links on your Facebook, Twitter, or Instagram feeds and encourage other people to share them as well.

    2    . Talk about the visible impacts if someone doesn’t see the big picture. Some people might not notice the effects of climate change and don’t understand how severe of a problem it is. Discuss the changes that have happened in your community due to climate change so they have a better idea of the problems.

Create art relating to climate change. Show the effects and images of climate change through your work. Art inspires so many people, so it might be a good way to show your concerns about climate change.

Then, you should keep in mind that climate change is the phenomenon of changing weather patterns in the world.     3    , and avoid politically biased or commercially-biased media.

Wildfires are a natural occurrence in forest ecosystem. To some extent, small wildfires can help the forest ecosystem work better by burning unwanted natural fuel, like fallen leaves and branches. Because if natural fuel piles up in forests, it will spark hot, intense and fast-moving fires, which brings more risks of the outbreak of disastrous natural fires.

As researchers study the perfect balance between allowing natural fires to burn and preventing them from threatening human life, some believe sheep offer a better way to retard the fast spread of a wildfire. Cuyama Lamb, an agriculture company, pulls its weight, currently running about 700 sheep that graze(放牧) on the grass. Working with the company, the fire department directs the sheep to the area in most need of natural fuel clearance. Their job is one thing: eat. The space the sheep clear can create a “burn break” that stops a wildfire in its track. The sheep are more efficient and cost-effective than using machines to do the same task, and they can get to places that technology can’t.

Schneider, the founder of the company, hopes the sheep allow Californians to “have a healthy relationship with fires” in the future. “We aren’t going to save the world by grazing a few sheep up on the hillsides, but we can work with others and do something for the world. Doing this, I believe we will have a sustainable future,” she said.

3 . Free solo climbing is a risky form of rock climbing where the climber makes the climb alone without ropes or any other protective things. In June 2017, Alex Honnold completed an ultimate free solo climb up El Capitan, a 3,000-foot wall in Yosemite National Park.

On a freezing November morning in 2016, Alex determined to take up a challenge-a free solo climb of the world’s most famous vertical（垂直的）cliff. Every step, he had to be extra careful to keep the balance. All the time he had to shine his headlamp on the cold, smooth part of stones to decide where he could next place his foot. Unlike parts of the climb higher up that Alex could climb with his strong fingers, this lower part he must manage with a perfect balance of fine skills and confidence.

Every move tied people’s hearts. The cameraman said. “Every time I got no response, I thought Alex was bailing. But it turned out that I was wrong-He was still moving on.”

More physically challenging parts wait for him to climb up with his feel and hands pressing the rock. The Free blast is the most frightening part. In 2016, after several failures, Alex knew he would try again. His foot tap-tap-tapped against the wall as if he was feeling his way into the huge rock, but he wouldn’t turn back this time. And then, he stood on the top and he made it!

People view free soloing differently. Critics regard it as risky, considering the long list of those who’ve died attempting it. Others, myself included, recognize it as the sport's truest expression. Such was the attitude of Austrian climber Paul Preuss, the father of free soloing. He believed that the spirit of mountain-climbing was to master a mountain with wonderful physical and mental skill.
