In a statistical report released by WHO, around 13 million deaths happen each year due to environmental issues. To make it worse, multiple diseases are a result of surviving in a low-quality environment. Lung diseases, asthma, stroke, issues in the heart are some of the examples. Green living such as making environment-friendly and sustainable food choices, energy conservation can help reduce pollution to some extent.

Firstly, the consumption of healthier foods can contribute to reducing pollution. People can start by consuming eco-friendly foods by buying from local farmers, buying organic and seasonal foods, etc. They are made of fewer pesticides that go into human bodies. Too much exposure to pesticides harms the natural hormones present in the human body and as a result, people face many health issues like lack of immunity, hormonal changes and also cancer.

Secondly, through energy conservation, people are saving both natural resources as well as money. The light bulbs and other electrical appliances that are available in the market produce 2.3 billion tons of carbon dioxide, which pollutes the air severely. Today there are LED bulbs available in the market that are eco-friendly and also save energy. Using such energy-efficient appliances reduces up to 30% of the annual electricity bill.

Many people go through life only thinking about their own well-being and that of those around them. In reality, the well-being of the environment is just as important in certain ways. Without a healthy and sustainable environment, their own health and ability to leave behind a sustainable planet to those who live after them is negatively affected. Therefore, two main environmental benefits can be realised with greener living.

Firstly, people can conserve natural resources. The natural resources that man has been enjoying are beginning to disappear. Due to population growth, it is estimated that the use of natural resources has more than tripled since 1970. At that rate, it is not difficult to see how these same resources will eventually become depleted. It is important to conserve those precious resources so that others after this generation can enjoy the same quality of living on this planet.

Secondly, people can reduce the harmful effects of climate change. Primarily due to human’s reliance on fossil fuels over the years, climate change is a real concern. People continue to release carbon dioxide into the atmosphere, further polluting the air. This is leading to dramatic changes in temperatures that need to be stopped. Greener living aims to do exactly that. For every person who makes an effort to reduce his or her carbon footprint in the world, climate change can begin to become less of a concern over time.

Festivals come with many traditions that bring happiness and joy. However, some of these customs may not be environmentally friendly and may need to be changed for a sustainable future. Below are three of them.

Balloons and sky lanterns: In countries such as China, India, and Japan, releasing balloons or sky lanterns provides a spectacular sight. They are also flown to bring good luck and send wishes to the sky. However, the litter left behind by the balloons and lanterns is hard to decompose. The frames of the lanterns can harm wild animals, and many animals mistake the balloons for food. Lanterns also caused wildfires in the past.

Fireworks: In Australia, the US, and many other countries, there are fascinating fireworks displays that people won't want to miss. However, fireworks actually release a lot of harmful chemicals into the air. Like sky lanterns, they can also cause fires.

Christmas trees: Real or fake Christmas trees are often displayed in almost every house, office, and shop during the festive season. When Christmas is over and the real trees go to landfills, they produce methane and carbon dioxide, which are two harmful greenhouse gases. Fake trees can be reused for many years, but during their production, harmful pollutants are released into the air. And when they end up in landfills, they will take hundreds of years to decompose.
