Water Pollution 💦

 Pollution has always been an important issue in the world as it is highly detrimental to humans’ health and the earth as well. As it is a critical issue that we have to be keen on, it is crucial for people to be aware of the causes and effects of pollution, let alone the ways to reduce pollution. We usually encounter news about air pollution on TV or social media, but it is relatively hard to see news related to water pollution. Water pollution is also a critical topic as it is directly associated with human activities and the main causes derive from products/substances that humans use. 



The main causes usually come from harmful substances like microorganisms, parasites, phosphates, nitrates, fertilizers, etc. Furthermore, sewage and wastewater can easily contaminate rivers and streams as the toxic substances get absorbed and dissolved into the water. This will naturally deteriorate the quality of water, which leads to disruptions of aquatic ecosystems and devastating effects on humans. As the toxic substances get dissolved into water, the harmful organisms are released and could possibly kill marine species. The leakage of wastewater, also known as sewage, can lead to eutrophic dead zones in which marine species are likely to die due to the lack of oxygen. 


Water pollution is detrimental to humans’ health and the environment as water is ubiquitous and there are lots of demands for water products. According to statistics, it is known that contaminated water sickens about 1 billion people each year and that diseases like cholera and typhoid could be derived from such water conditions. Moreover, swimming could also be a hazardous activity as people could show symptoms of skin rashes, respiratory infections, and hepatitis after getting out of the swimming pool or ocean. Not only this, but it also has a precarious effect on the environment as the introduction of toxic substances could trigger algae growth, leading to reductions in oxygen levels in the water.

Renewable Age 🌊

     Our natural resources are limited in the world, and they cannot be reproduced. Then where do we use coal energy in our real lives? Coal is a kind of rock with black surface which contains a high amount of carbon and hydrocarbons. Usually coal is found under the surface of the ground or the very deep soil layers of ocean. We usually use coal when we use electricity and drive the car. There are so many examples in our real lives to use coal, and even we can’t know or remember all the situations that we use it.      However, unlike natural resources, renewable energy is not limited as we can produce them by using material from nature such as sunlight, wind, water, ocean, bioenergy and so on. There are a few types of renewable energy. Solar energy Wind energy Hydro energy Tidal energy Geothermal energy Biomass energy Each picture shows the devices that help creation of each energy type, from solar energy to biomass energy in the order. 🌉🌊🌊🌊 (from Googl...

The Navdanya Movement 🌱

  Hyewon Lee Topic: The Navdanya Movement Date: 2021/12/09 The Navdanya movement was initiated in India to protect biodiversity and to promote the seed-saving movement around the world. It was founded by woman environmentalist Dr. Vandana Shiva as she wanted to guarantee seed freedom and food sovereignty for small farmers. This movement has progressed for about 30 years and was first initiated due to the sudden outbreak of the GMO crisis, which involves various health issues such as toxicity and allergenicity. The goal of the Navdanya movement is to ensure a new society in which economic justice and ecological responsibilities exist among consumers and farmers. Arising from this movement, Navdanya International was established in Italy in 2011 to demonstrate such qualities at an international level. One of its promotions refers to the Global Movement for Seed Freedom, which was launched to create unity among diverse organizations that have shown interest in saving seeds. As a matte...
