Animals in Agriculture

Animals have been used for agriculture for a very long time and they have been used in agriculture for working the farmland and providing fertilizer for crops. They have also been used for meat and dairy for food production. 40% of global land is used for raising livestock (Heggie, 2019). The plant diet of livestock is about 86% of grass and leaves (Heggie, 2019). According to National Geographic, the average American eats about up to 222 pounds of meat every year (Heggie, 2019). 

Most degradation of the environment is occurring because of animal agriculture (Conzachi, 2024). 65% of the nitrous oxide in the world is produced from animal agriculture, and uses up to 70% of land for animal agriculture (Conzachi, 2024). in conclusion, I think that the use of animals in agriculture is not a very conducive main source of food for the main food supply of the planet and plants are more productive to use in agriculture than animals.

Animal Rights

 Animal rights are principles that say that animals should be able to live life freely without being subjected by the desires of humans (The Humane League, 2022). These principles argue that animals deserve respect and are intelligent beings that should be treated well by people (The Humane League, 2022). I think that animal rights are basically based on the same principles as human rights, and that animals do deserve better regulations on the rights of animals.  These perceptions say that animals have a purpose outside of being used by people (World Animal Protection, 2023). some examples of animal rights include not using animals for food, not hunting animals, and having the habitats of animals protected to allow animals to live the way they choose (The Humane League, 2022). In conclusion I think that the rights of animals needs to be considered more and that people should allow animals to have more of those rights.  The Humane League. (2022, July 8).  Animal Right...

Companion Animals & Sheltering

 I think that we kind of have taking compainion animals for granted and that many compainion animals have become stray animals likely due to people not wanting them anymore so they dump their pets out on the street so that the people don't have to bare the costs of keeping pets when they find out they can't afford to keep their pet anymore. For example in Massacuthess a big housing crisis had impacted animals such as horses and dogs as bigger animals cost more and have more restrictions then animals like cats (Gibson, 2024).  In New York City the city's biggest animal shelter has had to contend with 3,200 dogs that were abanndoned which from 2022 was up 41% (Gibson, 2024). In competitive housing markets stricter rules that ban or limit pets have been made by landlords, these rules have effected mostly both large dogs and certian breeds of dogs (Gibson, 2024). In the United States and Canada about 40% to 50% of animals in shelters get euthanized, and most of these animals ar...

Animals in Science

 I think that using animals in science is a mixed topic as it has helped in finding out if cures and medicinesare safe for people to use or not and making sure they work which is not always a very concerte way of finding out stuff like that in my opinion as some things may work in humans but not in animals or vise versa. The main reason why animals are used in science in the first place is because animals are biologically simialar to people and are also likely to get the same dieseases that people could get as well (American Physiological Society, n.d). Because there are genetic alteration technologies avalible it has led to an increase in using genetically altered animals (NC3Rs, n.d).  Scientists will use animals if it is unethical to test people and there are no other alternetives (American Physiological Society, n.d). The environment the animals are kept is is very important, there are many guidelines set in place to be met for a specific type of species used in a laborato...
