Aral Sea dried up
The Aral Sea in Central Asia has shrunk to half its former size due to unsustainable cotton cultivation and irrigation projects. In 1959, Soviet officials diverted river flows to irrigate farms that supplied the growing cotton industry, causing the lake’s level to drop as the cotton blossomed. By the 1960s, the Aral Sea had shrunk by half, and by 1987, its level was so low that it split into two bodies of water. The eastern basin of the Aral Sea is now completely dry, likely for the first time in 600 years .
The destruction of the Aral Sea is often described as the most staggering environmental disaster of the 20th century. The United Nations Development Program highlights the numerous consequences of this catastrophe, including land degradation, desertification, drinking water shortages, malnutrition, and deteriorating health conditions. The loss of the Aral Sea has also led to the disappearance of a once-thriving fishing industry and the spread of salt-laden dust, which negatively affects crops and human health .
Efforts to understand and mitigate the impact of the Aral Sea’s disappearance include research and experimental farming projects. Near the village of Karauzyak, Japanese researchers are cultivating atriplex, a salt-tolerant plant, to explore its potential as a viable crop for the region. This plant helps retain scarce moisture in the soil and can be grown without extensive fertilizer use. Such initiatives aim to create sustainable agricultural practices and possibly revive small-scale farming and dairy industries in the devastated region .

Leafy greens
If we look through the window with greenery all around us, we can see green plants far away, a beautiful lake, beautiful grass trees swaying in the wind and giving us peace of mind, we live in greenery. All the fruits and vegetables we eat are green. Have you ever thought that all green vegetables are good for our body? Green vegetables are indeed packed with essential nutrients that promote overall health.
They are rich in vitamins, minerals, and antioxidants, which help boost the immune system, improve digestion, and reduce the risk of chronic diseases. Leafy greens like spinach and kale are high in vitamins A, C, and K, as well as iron and calcium. Cruciferous vegetables such as broccoli and Brussels sprouts contain compounds that support detoxification and may have cancer-preventing properties. Including a variety of green vegetables in your diet can contribute significantly to maintaining a healthy and balanced lifestyle.
Despite their nutritional benefits, green vegetables are the most likely to make you sick according to a 20-year study of California’s contaminated produce. One of the most famous outbreaks occurred in 2006 when spinach contaminated with the bacteria E. coli hospitalized 200 people and caused 18 deaths. Just this past June, a listeria outbreak in leafy greens hospitalized 18 people.
These incidents highlight the importance of food safety when consuming green vegetables. Contaminated produce can harbor harmful bacteria, such as E. coli and listeria, which can lead to severe illness and even death. To reduce the risk, it is crucial to thoroughly wash all fruits and vegetables, handle them properly, and stay informed about any food safety advisories. Despite the risks, green vegetables remain a vital part of a healthy diet, provided they are prepared and consumed safely.

What is shrinking sea?
A shrinking sea refers to a body of water that is diminishing in size over time, often due to a variety of environmental factors. One prominent example of a shrinking sea is the Aral Sea in Central Asia, once one of the largest inland bodies of water in the world. However, due to extensive irrigation projects diverting water from its tributary rivers for agriculture, the Aral Sea has experienced significant shrinkage over the past several decades. As a result, vast stretches of its former shoreline have been left dry, leading to ecological devastation and social upheaval in the surrounding regions.
The phenomenon of a shrinking sea can have far-reaching consequences for both the environment and human communities dependent on it. As the water level recedes, ecosystems that rely on the sea for sustenance are disrupted, leading to the loss of biodiversity and habitat degradation. Additionally, shrinking seas can exacerbate environmental challenges such as desertification and soil salinization, further exacerbating the impacts on local communities’ livelihoods and well-being. In many cases, efforts to mitigate the effects of shrinking seas involve complex management strategies aimed at restoring water levels and promoting sustainable water use practices, highlighting the need for coordinated action at local, regional, and global levels to address this pressing environmental issue.
The village of Karauzyak in western Uzbekistan is a dusty place. Surrounded by an arid landscape of dry scrub grasses and salt-crusted soils, it’s hard to believe the village was once along the banks of a swollen river, just 30 miles from the shore of the world’s fourth-largest lake. Over the last 50 years, that lake, the Aral Sea, has dried up almost entirely in what is often called the “world’s worst environmental disaster.” Now, it’s hard to farm much of anything in Karauzyak—except for atriplex, or saltbush. On a 3.5-hectare plot of land near the village, a team of Japanese researchers is growing this salt-loving plant, known scientifically as a halophyte, to see if it can be a viable crop for farmers in the region and even nurture a small dairy industry. They’ve fed it to cows at a nearby farm and found that it helps lock scarce moisture into the thirsty soil and can be grown without extensive fertilizer use.

Ancient times – poison in arrow
The Scythians, legendary nomadic warriors of the Eurasian steppes, were renowned for their formidable prowess in battle and their innovative use of biological warfare. Archaeological evidence from excavations of Scythian burial sites reveals the sophisticated tactics employed by these warriors, particularly in the design and deployment of their arrows. Scythian archers utilized barbed arrows with wooden shafts intricately decorated to resemble venomous vipers, creating a terrifying spectacle on the battlefield. The psychological impact of facing a barrage of arrows painted to resemble flying snakes with lethal fangs would have been daunting enough, but the true horror lay in the poison applied to the arrowheads.
The potency of the Scythian warriors’ biological arsenal was further heightened by their use of a notorious poison known as scythicon. Ancient Greek sources describe this deadly concoction as a vile blend of snake venom, decomposed vipers’ bodies, human blood, and dung, underscoring the brutality of ancient warfare. The application of scythicon to their arrows transformed these projectiles into lethal instruments capable of inflicting excruciating pain and death upon their victims. The combination of innovative weaponry and deadly toxins illustrates the Scythians’ ruthless determination to secure victory on the battlefield, cementing their reputation as some of the most feared biological warriors of antiquity.
