Farm animals and crop plants play a pivotal role in agricultural systems, contributing to food production, livelihoods, and environmental sustainability. However, tensions often arise when considering the natural behaviors and well-being of farm animals and crop plants against their utility value for human consumption. This essay explores the complex interplay between natural and utility purposes, addressing the challenges of reconciling the needs and interests of both stakeholders. by examining the ethical, ecological, and economic aspects of this issue, we can identify potential strategies to strike a balance that promotes both the well-being of farm animals and crop plants, as well as sustainable food production.

The beef industry plays a crucial role in Argentina's economy, and the central semi-arid rangelands of the country are a significant production area. However, beef production is associated with greenhouse gas (GHG) emissions, which contribute to climate change. Understanding the dynamics of GHG emissions in beef grazing systems is essential for implementing sustainable practices and mitigating their environmental impact. This article explores the factors influencing GHG emissions in beef grazing systems in central Argentina's semi-arid rangelands and discusses potential strategies to reduce emissions. Enteric fermentation, primarily carried out by rumen microbes in cattle, is a significant source of GHG emissions. Ruminants produce methane (CH₄), a potent greenhouse gas, during the digestion process. Central Argentina's semi-arid rangelands are characterized by extensive grazing systems, where cattle primarily feed on natural pastures. The quality of forage and grazing management practices can influence enteric methane emissions.

Actigraphy is a non-invasive method for monitoring and recording movement patterns in animals. This technology is commonly used in the field of sleep research, particularly in studies involving rats. In a rat behavioural sleep study, actigraphy can be used to collect data on sleep and wake patterns, which can provide insights into the mechanisms that regulate sleep and the effects of different interventions on sleep. This article will discuss the use of actigraphy for a rat behavioural sleep study in more detail, including the advantages and limitations of this method and the factors that need to be considered when using actigraphy to study sleep in rats. Actigraphy is a technique for measuring and recording movement patterns in animals. This technology uses an actigraph device, which is typically a small, lightweight device that is worn on the animal's body. The device contains an accelerometer, which detects movement and converts it into an electrical signal. This signal is then recorded and analyzed to determine the animal's activity levels over time.

Fish and seafood are important components of a healthy diet, providing a rich source of protein, omega-3 fatty acids, and various other essential nutrients. However, overfishing and unsustainable fishing practices have led to declining fish populations in many regions of the world, making it increasingly difficult to meet the growing demand for fish and seafood. As a result, there has been a growing interest in plant-based fish substitutes as a sustainable and ethical alternative. This paper provides an analysis of plant-based fish substitutes, examining their nutritional value, sensory characteristics, environmental impact, and market potential .Fish and seafood are known for their high protein content, as well as their omega-3 fatty acid profile. Omega-3 fatty acids are essential fatty acids that play a crucial role in brain function and cardiovascular health. However, plantbased fish substitutes vary in their nutritional content, with some products being more nutritious than others.
