Animal welfare can increase livestock productivity, and the impact on the environment. With the bio-tech advancements of ability to detect, treat and prevent diseases. What equipment is used to maintain the aseptic technique for a tissue culture facility? Maintaining PPE, transfer hood, filtered tips, and sterilized media. What are the negative and positive effects of agricultural practices on the environment? The environment can positively be affected by giving a positive effect to the organisms that follow; birds and predatory insect; and earthworms and flora. Negatively affecting the environment by increasing the amount of trapped green house gasses, decreasing the amount of biodiversity, and the accumulation of pesticides. Methods for bio-treatment of biological and chemical wastes? When discarding biological waste bacterium and other microorganisms are used to break down the organic material. When disposing of chemicals, they must be disposed of through the EHS Hazardous waste program. What are the negative aspects of the technologies used to create bio-fuels from biomass? A negative aspect to the use of biomass pertains to the amount of space that is needed for the technological conversion of organic material to an energy source. What are the positive aspects of the technologies used to create bio-fuels from biomass?
