Climate Change Requires the World’s Attention
In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body all that remained of the polar bear was “skin and bones”. An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology.
Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect, which helps keep the earth warm enough for people, plants and animals to live on, refers to the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane (沼气) and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the man-made greenhouse effect has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly.
There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heat waves causing deaths and economic losses.
Continued greenhouse gas emissions (排放) will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because it is all of us that share this planet. So what will you do to help?

Journey to the West
If you have a dream, go for it.
My dad talked of the jewel in China’s western part, Tibet Autonomous Region. Tibet was a region I wanted to see and discover but its remoteness and my inability to find the right time to go delayed my journey. After a few talks with my dad, we decided to take a pause in our lives for a few weeks in July 2019 to start an amazing adventure.
We started our journey on a Saturday morning at the Guangzhou train station in south China. We started the first leg of the journey admiring the mysterious mountains of south China. The next day it changed quite suddenly to the dry, waterless landscape of central-west China as we passed through Shanxi and Gansu provinces. That evening we arrived at Xining, Qinghai Province, where we got onto the Xining-Lhasa train.
We were greeted on the train with Tibetan yogurt. The train signs were also written in Tibetan, the beautiful handwriting matched its environment and people. The following afternoon we arrived in Lhasa. Lhasa, one of the highest-altitude cities in the world, is a gem hidden on the Qinghai-Tibet Plateau. We started our tour of the jewel by exploring the palace and watching local people do morning prays and dances in the park. Overlooking the Jokhang Temple, we enjoyed an amazingly beautiful breathtaking view, just like we had been in the fairyland. It’s a stunning (令人震惊的) golden temple in the middle of old Lhasa, which we visited next before wandering in the old quarters and Barkhor Street in the evening. Barkhor Street is the ideal place to try local food and buy local products.
The following day, we started our journey to the Qomolangma base camp by road from Lhasa. Along the way we stopped to admire the beautiful Yamdrok Lake, a huge freshwater lake that is one of the three largest sacred lakes (圣湖) in Tibet. Yaks (牦牛) in blankets and bells at the lake made for a picturesque impression of perfect countryside Tibet.
About a week later, the highlight came in the afternoon when we arrived at the Qomolangma base camp. We were staying in a guesthouse just next to the base camp. After dropping off our backpacks, we headed straight outside to see the magnificent Mt Qomolangma. There it was, the top of the mountain peeking through the clouds, astonishing us with its unbelievable height. We enjoyed the mountain waves and saw the beautiful clouds separated until the sunset over the peak, feeling I would have regretted for the rest of my life if I hadn’t made the journey.

4 Eco-Friendly Bikes to Ride This Summer
Nowadays, many drivers are searching for more environment-friendly ways to get around and are starting to look back to bikes. Bikes don’t require gas. In terms of convenience, bikes can be easier to park and can help riders get their daily exercise in.
Companies everywhere are beginning to take the traditional bike and adapt it to people’s needs. Below are eco-friendly bikes to consider adding to your morning ride.
1. Bamboobikes
Ccycles produces Bamboo Bikes. The company sources bamboo and carbon fiber joints for their bike frames. Bamboo is ideal for bikes because it can absorb significantly more shock than carbon fiber. It is also very lightweight compared to traditional bike materials, like steel. But bamboo is incredibly strong and can take on twice the compression force as steel.
2. Cowboy
Cow offers Cowboy, a bike hides the battery in its frame under the saddle. The removable battery takes about two and half hours to charge and has a range of roughly 31 miles, but the best part is the app features. The Cowboy app gives travelers a real time dashboard (仪器板) to check out their speed and distance. Riders never need to worry about getting lost since it has navigation and can pull up your route history from your ride states. This smart tech also gives riders updates about the bike’s status. The Cowboy has a high tech locking system so the owner is the only one who can start up the bike.
3. The Faraday Bicycle
Faraday ebikes have a 250W motor, and the battery can be fully charged in less than 4 hours. Faraday recently partnered with the organization One Tree Planted to help reforest California after the state underwent serious damage from wildfires that destroyed thousands of acres of land in the area. The company stepped up and donated $100 from every bike sold to plant 100 trees.
4. The Donky Bike
Wilson, who works for Donky, created The Donky Bike, a practical cargo bike. This bike was designed to easily carry a cargo load on the frame. Like any great workhorse, this bike was built with simple low-maintenance components and has a strong, durable frame.
