The illegal wildlife trade is the illegal trading of plants and wildlife. This illegal trading is worth an estimate of 7-23 billion [30] and an annual trade of around 100 million plants and animals. [31] In 2021 it was found that this trade has caused a 60% decline in species abundance, and 80% for endangered species. [31]
Loss of biodiversity also means that humans are losing animals that could have served as biological-control agents and plants that could potentially provide higher-yielding crop varieties, pharmaceutical drugs to cure existing or future diseases (such as cancer), and new resistant crop-varieties for agricultural species susceptible to pesticide ...
Other scientists have criticized the assertion that population growth is a key driver for biodiversity loss. [13] They argue that the main driver is the loss of habitat, caused by "the growth of commodities for export, particularly soybean and oil-palm, primarily for livestock feed or biofuel consumption in higher income economies."
A 2021 report in Frontiers in Conservation Science proposed that population size and growth are significant factors in biodiversity loss, soil degradation and pollution. [38] [39] Some scientists and environmentalists, including Pentti Linkola, [40] Jared Diamond and E. O. Wilson, posit that human population growth is devastating to biodiversity.
An important aspect of energy use in livestock production is the energy consumption that the animals contribute. Feed Conversion Ratio is an animal's ability to convert feed into meat. The Feed Conversion Ratio (FCR) is calculated by taking the energy, protein, or mass input of the feed divided by the output of meat provided by the animal.
A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.

Bioturbation is thought to have been an important co-factor of the Cambrian Explosion, during which most major animal phyla appeared in the fossil record over a short time. [2] Predation arose during this time and promoted the development of hard skeletons, for example bristles, spines, and shells, as a form of armored protection. [ 2 ]
There are carnivorous plants as well as herbivores and carnivores that consume plants and animals, respectively. Due to the extremely low nutritional content of the soil in which they grow and extra nitrogen is needed by the plants, therefore carnivorous plants eat insects. By photosynthesis, these plants continue to receive energy from the sun ...
