Soil conservation is essential in enabling tree plantations to restore soil fertility, prevent soil erosion, and enable biodiversity. Soil vigor and ecological balance are supported by organic farming, water conservation, and community participation. Besides, afforestation improves air quality, mitigates climate change, and restores ecosystems. They save natural resources for a greener tomorrow. Each planting conservation project gives future generations more hope for life.

Soil degradation is one of the challenges to sustainable tree plantations that have effects on tree growth, biodiversity, and overall ecosystem stability. The other factors affecting soil deterioration reduce soil productivity and consequently disrupt the ecosystem balance.

Deforestation: Abandoning any tree for the sake of agriculture or urbanization causes structural problems in soils and degrades organic matter. This ruins the whole purpose of a tree plantation because trees are very significant in ensuring soil stability and fertility.

Erosion: The deep topsoil, rich in nutrient content, is blown away by wind and washed away by water and difficult for plants to grow. More evidence of tree plantation is void of soil loss when trees take root-they hold the soil and prevent erosion.

Agrochemical Pollution: Excessive use of pesticides and synthetic fertilizers can reduce soil nutrient content. More importantly, they kill beneficial microorganisms. Hence, such degraded soil fetches low production from agricultural activities and drastically disrupts ecosystems, compelling the need for tree plantation in life.

Soil Compaction: Heavy machinery and overgrazing compact the soil, impeding aeration and infiltration. The resulting poor soil conditions hamper the growth of trees, derailing the purpose of tree plantations-aids in improving greenery and the environment.

Population, in human biology, the whole number of inhabitants occupying an area (such as a country or the world) and continually being modified by increases (births and immigrations) and losses (deaths and emigrations). As with any biological population, the size of a human population is limited by the supply of food, the effect of diseases, and other environmental factors. Human populations are further affected by social customs governing reproduction and by the technological developments, especially in medicine and public health, that have reduced mortality and extended the life span

Cereal farming, growing of cereal crops for human food and livestock feed as well as for other uses, including industrial starch and biofuel. Cereals, or grains, are members of the grass family (Poaceae) cultivated primarily for their starchy dry fruits. Wheat, rice, corn (maize), rye, oats, barley, sorghum, and some of the millets are common cereals.

Biology, the study of living things and their vital processes. The field deals with all the physicochemical aspects of life. The modern tendency toward cross-disciplinary research and the unification of scientific knowledge and investigation from different fields has resulted in a significant overlap of the field of biology with other scientific disciplines. Modern principles of other fields—chemistry, medicine, and physics, for example—are integrated with those of biology in areas such as biochemistry, biomedicine, and biophysics.

a neoclerodane diterpenoid, isolated from the Mexican hallucinogenic plant Salvia divinorum, is a potent kappa-opioid receptor agonist. Its biosynthetic route was studied by NMR and HR-ESI-MS analysis of the products of the incorporation of [1-13C]-glucose, [Me-13C]-methionine, and [1-13C; 3,4-2H2]-1-deoxy-d-xylulose into its structure. While the use of cuttings and direct-stem injection were unsuccessful, incorporation of 13C into salvinorin A was achieved using in vitro sterile culture of microshoots. NMR spectroscopic analysis of salvinorin A (2.7 mg) isolated from 200 microshoots grown in the presence of [1-13C]-glucose established that this pharmacologically important diterpene is biosynthesized via the 1-deoxy-d-xylulose-5-phosphate pathway, instead of the classic mevalonic acid pathway. This was confirmed further in plants grown in the presence of [1-13C; 3,4-2H2]-1-deoxy-d-xylulose. In addition, analysis of salvinorin A produced by plants grown in the presence of [Me-13C]-methionine indicates that methylation of the C-4 carboxyl group is catalyzed by a type III S-adenosyl-l-methionine-dependent O-methyltransferase.

In 2017, while red-flagging the concern of biological warfare at an international security conference, philanthropist businessman Bill Gates underlined how a respiratory-spread pathogen could kill 30 million people in less than a year. Coronavirus has not emanated from a terrorist module, but it seems to have the potential to become exactly the global epidemic Gates was warning against. Within three months of its outbreak, coronavirus has already claimed over 3,200 lives and has spread to over 93,000 cases across 70 countries. Outside China which has borne most of the disease brunt, Iran has reported 92 deaths while Italy has reported 79. With WHO declaring it a public health emergency of international concern, the disease has also made its way to the US amid much criticism of the Trump administration’s initial handling of the health threat.

Space research is scientific study carried out in outer space, and by studying outer space. From the use of space technology to the observable universe, space research is a wide research field. Earth science, materials science, biology, medicine, and physics all apply to the space research environment. The term includes scientific payloads at any altitude from deep space to low Earth orbit, extended to include sounding rocket research in the upper atmosphere, and high-altitude balloons.
