The human population exploits and depends on many animal and plant species for food, mainly through agriculture, but also by exploiting wild populations, notably of marine fish. [10] [11] [12] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle, 1.2 billion sheep and 1 billion domestic pigs. [12 ...
Food biodiversity is defined as "the diversity of plants, animals and other organisms used for food, covering the genetic resources within species, between species and provided by ecosystems." [ 1 ] Food biodiversity can be considered from two main perspectives: production and consumption.
Global average human diet and protein composition and usage of crop-based products [11] (more statistics) Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. [12] Most human plant-based food calories come from maize, rice, and wheat. [13]
A 2023 review found that substituting animal-source with plant-based foods is associated with a lower risk of cardiovascular disease and all-cause mortality. [16] A 2024 review found that plant-based meat alternatives have the potential to be healthier than animal-source foods and have smaller environmental footprints. [17]
Food products produced by animals include milk produced by mammary glands, which in many cultures is drunk or processed into dairy products (cheese, butter, etc.). Eggs laid by birds and other animals are eaten and bees produce honey , a reduced nectar from flowers that is used as a popular sweetener in many cultures.
Pygmy hunter-gatherers in the Congo Basin in August 2014. A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, [1] [2] that is, by gathering food from local naturally occurring sources, especially wild edible plants but also insects, fungi, honey, bird eggs, or anything safe to eat ...
Ollie. If your dog is a picky eater and needs some crunch (aka, kibble), Ollie is a great alternative to processed dry food. Yes, they have excellent AAFCO-approved human-grade recipes, but you ...
Human intervention through artificial selection of animals with desirable characteristics further increased the differentiation among and uniformity within breeds. Examples of traits that have been deliberately selected by humans include growth rate, milk or egg production, coat color, meat quality, and age of maturity, among many others.
