Want to do something good for the environment? Ditch animal products, go vegan!
A vegan diet includes reduced consumption of animal products, which have a higher environmental impact than plant-based products.
Vegan diets, which are rich in plant-based organic foods, may be better for the planet than one high in animal products, a study has found. The study, published in the journal Frontiers in Nutrition, is the first to investigate the environmental impacts of both dietary patterns and farm production systems. It is also the first to investigate the environmental impact of organic food consumption using observed diets rather than models, researchers said.
According to hindustantimes.com, many organizations, including the UN’S Food and Agriculture Organization, advocate the urgent adoption of more sustainable diets at a global level. Such diets include reduced consumption of animal products, which have a higher environmental impact than plant-based products. This is mainly due to the high energy requirements of livestock farming as well as the very large contribution of livestock to greenhouse gas emissions. Intensive livestock production is also responsible for significant biodiversity loss due to conversion of natural habitats to grass and feed crops.
The method of food production may also influence sustainable diets, researchers said. Organic agriculture is generally considered more environmentally friendly than other modern production techniques. However, while many studies have investigated environmentally sustainable diets, these have rarely considered both dietary choices and the production method of the foods consumed.
“We wanted to provide a more comprehensive picture of how different diets impact the environment,” said Louise Seconda from the French Agence de l’environnement et de la Maitrise de l’energie and the Nutritional Epidemiology Research Unit.
“In particular, it is of considerable interest to consider the impacts of both plant-based foods and organic foods,” said Seconda.
To do this, researchers obtained information on food intake and organic food consumption from more than 34,000 French adults. They used what is called a ‘provegetarian’ score to determine preferences for plant-based or animal-based food products.
The researchers also conducted production life cycle environmental impact assessments at the farm level against three environmental indicators: Greenhouse gas emissions, cumulative energy demand and land occupation.
“Combining consumption and farm production data we found that across the board, diet-related environmental impacts were reduced with a plant-based diet — particularly greenhouse gas emissions,” said Seconda.
“The consumption of organic food added even more environmental benefits for a plantbased diet. In contrast, consumption of organic food did not add significant benefits to diets with high contribution from animal products and only moderate contribution from plant products,” she said.
However the researchers caution that the environmental effects of production systems are not uniform and can be impacted by climate, soil types and farm management. South Korea will push to build the country’s largest floating solar farm on the western coast to expand power generation from ecofriendly energy sources, state-run company Korea Hydro and Nuclear Power (KHNP) said.
KHNP said it has signed a memorandum of understanding with Hwaseong Solar Energy, a local renewable energy firm, to develop the floating 100 megawatt-capacity solar power plant in Hwaseong, 70 kilometers southwest of Seoul, Yonhap wrote.
The project aims to place an array of photovoltaic panels on a structure that floats on Hwaseong Lake, a manmade lake on the western coast.
The state utility firm said it has signed a long-term lease with the provincial government to use 861,000 square meters of the lake, or 8.3 percent of the site.
The 220 billion won ($202 million) project is part of KHNP’S plan to invest 10 trillion won by 2030 to expand renewable energy sources, including solar and wind power.
The government plans to increase the ratio of renewable energy from the current seven percent to 20 percent by 2030. The increase will allow renewable energy output to reach a capacity of 63.8 gigawatts.
