London . The food we eat has a widespread effect on our planet. About half of the living land on Earth is to Agriculture and there is a quarter emission of greenhouse gas emissions in the world. Meat and dairy especially have about 14.5 percent of Greenhouse Gas Emissions. Therefore, changing what we eat can help reduce carbon emissions and promote sustainable farming. But “climate -friendly” are many diets. Perfectly plant -based vegetarian diets are more prevalent, and eggs and dairy diet are also considered involved in it. There are also “flexitarian” diets, where three-fourth of meat and dairy diets are replaced by plant-based food.

“Flexitarian” diet is a form of food that is mostly preferred by plant -based foods, while meat and other animal products are allowed. It can be considered a semi-vegetarian diet. Climate (climate (climate) diet. A form that was created by the non-profit organization 'Climate Network' and is considered healthy, climate friendly and nature friendly. The diet still allows you to eat meat and other high emitted foods such as pork, poultry, fish, dairy products and eggs. So this is a new form of “climate - non -vegetarian diet”. However, the diet encourages you to overthrow the food wastage, avoiding food waste and selecting local foods.

Water and land use
To save our planet, we should also consider the use of both water and land. For example, beef requires about 15,000 liters of water per kg. Some vegetarian foods such as avocado and almonds also have a very high water content, but in total, a standard meat-based diet consumes about half of the water-based diet. The low requirement of agricultural land will help prevent deforestation and protect biodiversity. Land can also be used to re -revive large areas which will become a natural reserves of carbon dioxide.

A plant -based diet is also usually healthy. Meat, especially highly processed meat, high blood pressure, heart disease and cancer is associated with major health issues. However, meat, dairy and fish are the main sources of some essential vitamins and minerals such as calcium, zinc, iodine and vitamin B12. What is the ideal global diet to reduce greenhouse gas emissions, protect the housing from destroying and live longer live? By the way, I suggest being a “ultra-flexiterian”-diet of most plants based foods, but one that allows meat and dairy products to excessive amounts, but red and processed meat is completely restricted.
