In Sarek National Park, I wake up to the sound of the wind buffeting the cloth of my tent.     1     (stand) at the edge of the mountain, I find     2     (branch) of the Rapa River flowing through the valley below. Sarek’s mountains used to     3     (cover) by vast sheets of ice. Around 9,000 years ago, this ice melted, with about 100 glaciers     4     behind. Soon after, reindeer began to arrive. Following the reindeer    5     (be) the Sami people, who made this territory their home. In 1909,     6     (keep) the land in its natural state, the government made Sarek a national park.

For hundreds of years, the Sami lived off reindeer. With reindeer    7    the move, the Sami would pick up their tents and accompany them. Today, most Sami have houses in villages near Sarek and live     8     modern life. But every spring, a small number of Sami still follow their reindeer into the valleys of Sarek,     9     they live in tents and enjoy their traditions. Nothing could be     10     (good) than breathing the fresh air and enjoying this great adventure in such a beautiful and wild place.

More and more children are suffering from eco-anxiety, which is     1    problem that causes people to worry a lot about the future of Earth and the life on it. They worry about climate change,    2    (pollute) and the loss of biodiversity. This has urged education experts     3    (call) for more teaching in schools about climate change, wildlife and the environment. So necessary is knowledge of them nowadays     4    experts believe it should be taught to all year groups.

The Teach the Future campaign finds that only one in four schoolchildren    5    (feel) they know enough about the climate crisis. It says this is leading to move children    6     (struggle) with eco-anxiety and worrying about the planet. A conservation organization, Earth Rangers,    7    (take) action to address the problem of eco-anxiety since it noticed that.

It says, Eco-anxiety does have a big effect    8    children in many ways. This includes feelings of fear and hopelessness. It is    9    (importance) to research and understand the ways in which we can help children deal with these feelings     10    (effective). In the meanwhile, schools should create conservation activities and help children teach their parents how to protect nature.

One type of recycling, called downcycling, involves repurposing a material into a new product of lesser quality. It can include varying grades of plastic, paper products, and other materials.

Downeycling     1     (know) as downstream recycling. It is most common in terms of     2     (industry) materials. These products lose their value as they are recycled,     3     limits their capacity for new use. Their recycled form is typically both weaker and cheaper     4     their original one. White writing paper, for example, is often downcycled into cardboard; once downcycled to this new form, it can no longer be used as white paper again.

    5     (give) products a new life is considered a good way to reuse materials and avoid waste. Once downcycled to their full capacity however, these materials are eventually so degraded that they cannot be reused further. Since downcycled products are considered of lower quality than their original form, they cannot be used in remaking their original product.

Products are provided with codes     6     (determine) their grades and whether or not they may be recycled. Plastic, glass, and aluminium products     7     (code) with the number one may be remade into something     8     equal or greater value. This type of recycling is known as upcycling, and represents the forward compatibility of recycled components.

Items available for downcycling often require additional chemicals, energy,     9     other treatments in order to transform them into something usable. Durable plastic products in particular require much additional treatment. Trash bins, tables, and chairs are also considered materials with     10     high energy cost to recycle.
