We, humans, have been following a basic pattern of consumption since decades across the globe. This was justified, because earlier there was no requirement to change the way we eat. We also never felt the need to even ponder on the impacts of our eating habits. However, times are now changing and we need to think of what and how we are eating on a daily basis. As we are all aware, protein is one of the major key nutrients in our balanced diet. These building blocks of our body are required in adequate quantity to maintain a healthy living. Milk, meat, dairy products, eggs, meat or even all animal-derived products are often considered to be the best source of protein. Under this impression, people have been consuming them for decades to fulfill their protein requirement.. But you must be wondering why shall we change and eat something different from what we currently are? Why not just stick to our ongoing eating habits? Little do we know, that these protein sources are unsustainable and cause a major ecological imbalance. Well….. you must know the cost we are paying due to this increasing reliance on animal-derived protein . More requirement of land, water and feed which could be utilized. Increasing emissions of greenhouse gasses Transportation in feeding and more…… I strongly believe that switching to sustainable protein sources be it coming from meat, eggs, fih or dairy will play a key role in protecting our climate. Also, the proconcieved notion that total protein can only be obtained from animal sources is gradually dimishing owing to the advancemnt in science and technology. With this in mind, even a single switch can lead to a greener future.
