The Impossible Burger is a burger that tastes exactly like beef, but it was made using vegetables and science. There are many kinds of “veggie burgers” for vegetarians (素食者)，but this one is made for meat lovers. The company that makes this burger, Impossible Foods，wants to change the food that people eat to reduce climate change.

Scientist Celeste works on the flavor (风味) and texture (纹理) of the burger. She looks for the key points of beef its flavor, smell and look. Then those points are copied using plant based ingredients (成分)，which make the burger look and taste like blood and give it a meaty texture.

The Impossible Burger has the same nutrition as beef, without the unhealthy parts. In fact, taste, nutrition and reducing climate change were all equally important when creating the burger.

Cows are actually terrible for the environment. They need lots of land and water, and they create greenhouse gases. However, an Impossible Burger uses 95% less land, 75% less water, and creates 85-87% less greenhouse gases than a beef burger.

That's why this burger was made for meat lovers. The goal is for them to eat less meat in order to protect environment. At the same time they can still eat delicious burgers that taste like real meat.

Want to try the Impossible Burger? It can be found in Texas, Nevada, California and New York. Below are some restaurants serving it in L. A. and New York City.

Milan-based company Krill Design is changing the way we think about waste by creating furniture products from a plastic-like biomaterial named Rekrill. The special material is biodegradable, and can be used repeatedly.

Founded in 2018, Krill uses fruit skin, orange seeds and coffee grounds collected from businesses in Italy to create their unique designs, including bookends, clocks, bowls, and lamps. Each product is made through a four-step process. “There are a lot of companies that create designs, and we want to be different,” says MarcoDi Maio, director of operations at Krill.

Krill has worked together with some well-known brands and has also joined in a Co. ffee Era project with the government of Milan to reduce coffee waste produced in three of the city's neighborhoods. Krill has made products that match the color of food waste. For example, bright orange products are from orange skin and rich dark brown products are from coffee grounds.

Rekrill is as strong as wood and breaks down safely unless it's touched by water or acidity. It is also safe for fish to eat. But despite its eco-friendly benefits, Rekrill is more expensive than common plastic due to its complex production process. However, Krill hopes that as awareness of the environmental impact of plastics grows, Rekrill will be more widely used. Krill is exploring the use of other food waste, such as eggshells and leftover tomatoes and grapes, aiming to make its production process more efficient and cost-effective.

The company believes Rekrill is the material of the future. Every small step they take toward a sustainable world contributes to a more recyclable economy and inspires others to follow suit.
