March 22 was the United Nations' World Day for Water, and this year's "Water and Climate Change" was chosen as the key theme. With industrial growth and population growth, we are increasingly demanding water, but climate change, water waste and water pollution caused by this are threatening water around the world. Water security has emerged as an international issue, with experts saying that the possibility of a water war is much greater than the possibility of a nuclear war in the future. "Water stress is emerging as a form of international conflict and is threatening human food," warned Andrew Steer, head of the World Resources Institute. Korea is no exception. Korea is a food security crisis. The grain self-sufficiency rate is only 23 percent (average between 2015 and 2017 and the Korea Rural Economic Institute), ranking last among OECD members. At the same time, South Korea is the country that pointed to its high "water stress" index in a docum...

Even in Korea, where huge amounts of plastic are used every year, we can realize the change. Since last summer, coffee shops have been serving coffee in mugs instead of disposable containers. You can also see paper straws that replace plastic straws or multi-use stainless steel straws. Starbucks Korea offers eco-friendly paper straws at all stores nationwide from the 26th. Not long ago, there was news that McDonald's in China was stopping providing plastic straws. Also, voices calling for changing all food wrappers to eco-friendly ones are gaining strength. Foods that fill the shelves of large marts are usually made of materials that harm the environment, such as plastic, vinyl film, and paper. It rarely breaks down even when buried in the ground, and it makes the Earth sick. The "2019 Food Trend" recently released by Hall Food, the largest eco-friendly food distributor in the U.S., also said, "The packaging of eco-friendly materials will become a trend." Many c...

These days, we do self-quarantine and do a lot of internet shopping instead of going outside. Use apps like Amazon, eBay, Taobao, and Coupang to buy and ship things home. Of course, this is a really good alternative. Internet shopping, which has the advantage of living in a global disaster such as a disaster movie, not meeting people as much as possible, not having a conversation, and being able to get necessary things so easily, has saved many people. But if the goods are delivered to my house like this, the goods come in the box. When you open the box, there is a supplement. Of course, I understand. I put it in to deliver the goods safely, but sometimes I think it's too much. I once delivered Clam chowder soup from the United States. But each of the five came from different boxes with supplements that were at least five times larger than their own size. In China, they ordered 10 flower pots (really small ones). It was delivered to our school in huge styrofoam. I thought I was goi...

   Have you ever heard of carbon footprints? They say that we can measure the impact of living on the Earth on the environment through carbon footprint. Let me tell you today about the steps related to the environment, from environmental footprint to water footprint to ecological footprint. Types of Environmental Footprint Carbon footprint A carbon footprint means the total amount of greenhouse gases generated directly or indirectly by individuals or organizations! The total amount of greenhouse gases includes all the fuel and electricity we commonly use in our daily lives. A carbon footprint is a concept in kg that was created to reduce emissions by tracking where carbon dioxide is emitted a lot. It also connects to the number of trees we need to plant. Wouldn't it be better to save energy to reduce carbon footprint? ​A  water footprint Water footprint refers to the total amount of water used during the entire process of unit product and unit service producti...

At a price of self-price, countless kinds of garbage pour out during quarantine. The way to throw away the garbage is different from country to city, thinking about the environment a little more. So what I'm going to say today is why we have to recycle 1. Separated garbage can be recycled again, saving resources. 2. I only throw away the garbage that I can't recycle, so there's less trash. 3. For example, recycling cans by separating them costs less than making new cans, which saves money. 4. Non-corrosive garbage such as plastic bottles and glass bottles can be separated and collected, thus making the environment clean. 5. Resource utilization increases by distinguishing between recycled items and non-recycling and incineration materials. : Iron, aluminum, glass bottles, pet bottles, paper, etc. 6. It is economical because it can reduce the cost of incineration or landfill. Reduced power costs and improved incineration efficiency by reducing the amount of time spent on inc...
