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.
