Growing Greenhouse Gas Emissions From The Livestock & Poultry Industries Driving The Need For Alternative Protein Sources

Currently, most of the protein produced worldwide comes from livestock meat. Approximately 70% of agricultural land and 30% of the total land on earth is used to raise livestock to meet the world’s protein needs. Thus, it is neither feasible nor sustainable to dedicate more land to livestock production. Moreover, the global livestock industry has already taken an enormous toll on the environment through the high use of land and water. The livestock industry emits more greenhouse gases than planes, trains, and automobiles combined. Considering people’s current eating habits, the adoption of high-quality alternative protein sources, such as edible insects, has become imperative in order to reduce pollution, habitat destruction, and the abuse of natural resources.
According to the Population Reference Bureau (PRB), the global human population is expected to grow by 75 million annually (1.1% per year). By 2050, the world population is expected to reach 9.9 billion, increasing by 25.3% compared to ~7.9 billion in 2021. This population growth is expected to burden the production and supply of food. Hence, considering the world’s growing population and the increasing demand for traditional meat products, edible insects could be an effective solution to many of these problems, as insects are full of protein and rich in essential micronutrients, such as iron and zinc.
Moreover, an increasing number of health-conscious consumers are demanding environmentally safe and chemical-residue-free meat, encouraging meat producers to adopt insect-derived feed, such as BSFL protein meal. Furthermore, insects are a cheaper alternative protein source for animal feed compared to fish and soy meal. Hence, insects contribute to the production of high-quality and low-priced feed for livestock, poultry, and fish. Breeding insects has environmental advantages, such as lowering greenhouse gas emissions, water pollution, and land use. Crickets need 12x less feed, 15x less land, 2000x less water, and produce 100x lower greenhouse gas emissions compared to cattle to produce the same amount of protein. Crickets can be fed food waste, like banana peels or rice bran.
Thus, edible insects have emerged as an important alternative source of protein for livestock production and human consumption, driving demand and boosting the growth of the edible insects market. Meticulous Research,® in its latest publication on the ‘Edible Insects Market,’ states that the edible insects market is projected to reach $17.9 billion by 2033, at a CAGR of 28.6% during the forecast period of 2024 to 2033, while in terms of volume, the market is expected to reach 4.7 million tons b y 2033, at a CAGR of 36.3% from 2024 to 2033.
