Global wildlife populations have decreased by 68% since 1970 as a result of human activity, particularly overconsumption, population growth and intensive farming, according to a 2020 World Wildlife Fund’s Living Planet Report and its Living Planet Index measure, which is further evidence that humans have unleashed a sixth mass extinction event.

In November 2008, almost 900 plucked and ”oven-ready” owls and other protected wildlife species were confiscated by the Department of Wildlife and National Parks in Malaysia, according to TRAFFIC. The animals were believed to be bound for China, to be sold in wild meat restaurants. Most are listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora which prohibits or restricts such trade.

A November 2008 report from biologist and author Sally Kneidel, PhD, documented numerous wildlife species for sale in informal markets along the Amazon River, including wild-caught marmosets sold for as little as $1.60. Many Amazon species, including peccaries, agoutis, turtles, turtle eggs, anacondas, armadillos are sold primarily as food.

Others in these informal markets, such as monkeys and parrots, are destined for the pet trade, often smuggled into the United States. Still other Amazon species are popular ingredients in traditional medicines sold in local markets. The medicinal value of animal parts is based largely on superstition.

Many animal species have spiritual significance in different cultures around the world, and they and their products may be used as sacred objects in religious rituals. For example, eagles, hawks and their feathers have great cultural and spiritual value to Native Americans as religious objects. In Hinduism the cow is regarded sacred.

Animals living in the wild experience many harms due to causes which are either completely or partially natural, such as starvation, dehydration, parasitism, predation, disease, injury and extreme weather conditions.

This subsection focuses on anthropogenic forms of wildlife destruction. The loss of animals from ecological communities is also known as defaunation.

Exploitation of wild populations has been a characteristic of modern man since our exodus from Africa 130,000 – 70,000 years ago. The rate of extinctions of entire species of plants and animals across the planet has been so high in the last few hundred years it is widely believed that we are in the sixth great extinction event on this planet; the Holocene Mass Extinction.

A dominant tigress they called Padmini killed a 250 kg / 550 lb male nilgai – a very large antelope. They found her at the kill just after dawn with her three 14-month-old cubs, and they watched uninterrupted for the next ten hours. During this period the family was joined by two adult females and one adult male, all offspring from Padmini’s previous litters, and by two unrelated tigers, one female the other unidentified. By three o’clock there were no fewer than nine tigers round the kill.

With smaller prey, such as monkeys and hares, the tiger bites the nape, often breaking the spinal cord, piercing the windpipe, or severing the jugular vein or common carotid artery.

In the 1990s, a new approach to tiger conservation was developed: Tiger Conservation Units (TCUs), which are blocks of habitat that have the potential to host tiger populations in 15 habitat types within five bioregions. Altogether 143 TCUs were identified and prioritized based on size and integrity of habitat, poaching pressure and population status. They range in size from 33 to 155,829 km2 (13 to 60,166 sq mi).

In 2016, an estimate of a global wild tiger population of approximately 3,890 individuals was presented during the Third Asia Ministerial Conference on Tiger Conservation.

Dairy farms generally sell male calves for veal meat, as dairy breeds are not normally satisfactory for commercial beef production. Many dairy farms also grow their own feed, typically including corn, alfalfa, and hay. This is fed directly to the cows, or stored as silage for use during the winter season. Additional dietary supplements are added to the feed to improve milk production.

In some societies, collective farming is the norm, with either government ownership of the land or common ownership by a local group. Especially in societies without widespread industrialized farming, tenant farming and sharecropping are common; farmers either pay landowners for the right to use farmland or give up a portion of the crops.

The land and buildings of a farm are called the ”farmstead”. Enterprises where livestock are raised on rangeland are called ranches. Where livestock are raised in confinement on feed produced elsewhere, the term feedlot is usually used.

In 1910 there were 6,406,000 farms and 10,174,000 family workers; In 2000 there were only 2,172,000 farms and 2,062,300 family workers.

In the United States, there are over three million migrant and seasonal farmworkers, 72% are foreign-born, 78% are male, they have an average age of 36 and average education of 8 years. which is significantly below the 2005 U.S. poverty level of $19,874 for a family of four.

In 2007, corn acres are expected to increase by 15% because of the high demand for ethanol, both in and outside of the U.S. Producers are expecting to plant 90.5 million acres of corn, making it the largest corn crop since 1944.

According to the World Bank, ”most empirical evidence indicates that land productivity on large farms in Pakistan is lower than that of small farms, holding other factors constant.” Small farmers have ”higher net returns per hectare” than large farms, according to farm
household income data.

Nepal is an agricultural country and about 80% of the total population are engaged in farming. Rice is mainly produced in Nepal along with fruits like apples. Dairy farming and poultry farming are also growing in Nepal.

According to the UN, ”green agriculture directs a greater share of total farming input expenditures towards the purchase of locally sourced input. A local multiplier effect is expected to kick in. Overall, green farming practices tend to require more labour inputs than conventional farming (FAO 2007 and European Commission 2010), creating jobs in rural areas and a higher return on labour inputs.”

The majority of minerals and organic molecules crystallize easily, and the resulting crystals are generally of good quality, i.e. without visible defects. However, larger biochemical particles, like proteins, are often difficult to crystallize. The ease with which molecules will crystallize strongly depends on the intensity of either atomic forces in the case of mineral substances, intermolecular forces organic and biochemical substances or intramolecular forces biochemical substances.

Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallization occurs in a crystallizer. Crystallization is therefore related to precipitation, although the result is not amorphous or disordered, but a crystal.

when a saturated solid – liquid solution is cooled slowly, solid Solute settles down with a extremely regular arrangement of its constituent particles atoms, molecules or ions.

The crystal growth is the subsequent size increase of the nuclei that succeed in achieving the critical cluster size. Crystal growth is a dynamic process occurring in equilibrium where solute molecules or atoms precipitate out of solution, and dissolve back into solution. Supersaturation is one of the driving forces of crystallization, as the solubility of a species is an equilibrium process quantified by Ksp. Depending upon the conditions, either nucleation or growth may be predominant over the other, dictating crystal size.
