Climate change is widely recognized as the defining issue of our time, and we find ourselves at a critical juncture in addressing its repercussions. The effects of climatic changes permeate various aspects of life on Earth, including increasing occurrences of floods, landslides, droughts, storms, sea-level rise, and other natural disasters. With the notion of \"global boiling,\" we aim to intensify awareness and prompt more radical actions to mitigate the worst consequences of climate change. It is designed to sound the alarm and trigger more radical action to stave off the worst of climate change. The escalating global warming, driven by human emissions of heat-trapping greenhouse gases, is already significantly altering the Earth's climate and leaving a profound impact on the environment. The melting of glaciers and ice sheets, earlier breakup of lake and river ice, shifts in plant and animal ranges, and earlier blooming of plants and trees are some of the observable manifestations. Furthermore, climate change has emerged as a critical factor in exacerbating the risk and severity of wildfires worldwide, with key influences stemming from temperature variations, soil moisture, and the presence of potential fuel sources such as trees and shrubs. These interconnected factors underscore the direct and indirect ties between climate variability","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135807488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"An Investigation of Cutting Down of Trees as Human Rights Abuse in the Global World","authors":"M. Rusetuka","doi":"10.47604/ijes.1959","DOIUrl":"https://doi.org/10.47604/ijes.1959","url":null,"abstract":"Purpose: To investigate the current cutting down of trees as a human rights abuse in the global world. \u0000Methodology: The study employed a documentary review secondary data collection method.  Documentary review is a data collection technique in which data is gathered from reports, journals, Magazines, Newspapers, and articles that have data linked to the research being undertaken (Creswell, 2014). A documentary review was employed to investigate the current cutting down of trees as a human rights abuse in the global world by examining the causes, impacts, and how it’s an abuse of human rights. \u0000Findings: It was found out that cutting down trees in the forest is deforestation. The direct causes are caused by people who clear land for crops, and animal grazing and obtain wood for fuel, manufacturing, and construction. The study found that deforestation affects many species that are so specialized to microhabitats within the forest that they can only be found in small areas. Their specialization makes them vulnerable to extinction. In addition to the species lost when an area is totally deforested, the plants and animals in the fragments of forest that remain also become increasingly vulnerable, sometimes even committed, to extinction. The edges of the fragments dry out and are buffeted by hot winds; mature rainforest trees often die standing at the margins. Cascading changes in the types of trees, plants, and insects that can survive in the fragments rapidly reduce biodiversity in the forest that remains. The study further found that deforestation is a human rights abuse because it denies people the right to life. Trees reduce the amount of stormwater runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding but when they are cut they cause flooding which erodes people’s houses and cause losing lives which is a human rights abuse against the declaration of human rights 1948 (Everyone born in this world has human rights that must be protected by the law). \u0000Unique Contribution to Theory, Practice and Policy: the governments of the global world should work as the team to fight this devise by ending deforestation and thwarting pandemics to address six of the United Nations’ 17 Sustainable Development Goals: the guarantee of healthy lives, zero hunger, gender equality, responsible consumption and production, sustainably managed land, and climate action (intact tropical forests absorb carbon dioxide, whereas burning them sends more CO2 into the atmosphere).","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"4 3 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79952030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, changes in the surrounding temperature may have an effect on the chemicals' toxicity to mosquitoes. The goal of the current study was to determine how temperature affected Culex pipiens' reactions to Commiphora molmol resin, Mirazid, crystalline (CASA), and acetylsalicylic acid in pharmaceutical form (PASA). Bioassay tests were carried out on the 3 rd instar larvae under laboratory conditions, and the LC 50 of each compound was determined. The LC 50 of the four compounds were used to study the temperature-toxicity relationship, while the LC 50 of Mirazid and (PASA), as the most toxic compounds, were used for further biochemical studies. Results indicated that, Mirazid was the most toxic compound, with LC 50 of 28.3 ppm followed by C. molmol resin with LC 50 of 41.6 ppm while the CASA was the least toxic compound with LC 50 of 799.7 ppm. The temperature has a considerable impact on Cx. pipiens larval susceptibility to the tested compounds. High temperature (36 ̊C) resulted in high mortality rate (72.88, 78.20, 58.8 and 62.12 % for of C. molmol resin, Mirazid, CASA and PASA, respectively. Moreover, there were significant changes in α-esterase, β–esterase and glutathione -S-transferase levels as well as the total protein content in the treated larvae due to the change in temperature. The efficacy of Mirazid and C. molmol resin under wide range of temperatures made these compounds suitable candidates for controlling Cx. pipiens .","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"10 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81693836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rice cultivars with considerable salt tolerant capabilities have been developed and improving their performance in the salt-affected lands is crucial. Herein, the effects of humic acid (100 mg/l) as a stress-alleviator and a biostimulant on the germination, vegetative growth, and yield of Giza 179 rice cultivar under increased salinity (0.55, 3.40, 6.77, 8.00 mS/cm) were investigated. The humic acid-induced effects were also validated in salt-affected field. Salinity retarded Giza 179 germination-related traits which were associated with a significant decline in Gibberellic acid (GA 3 ) content and α-amylase activity. Also, salinity reduced the Giza 179 vegetative growth which was correlated with accumulation of shoot Na + , proline, and total soluble proteins (TSP), induction of membrane injury, and reduction of photosynthetic pigments. Humic acid significantly decreased most of the salinity-induced injury; however, it increased the salinity-induced synthesis of proline and TSP. The deteriorative effects of salinity during germination and vegetative stages were translated into significant reduction in grain yield and quality whereas the ameliorative effects of humic acid against salinity were reflected in better overall growth and yield. These results indicate the efficacy of humic acid in maintaining vigorous germination, growth, and yield in salt-affected lands.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"12 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79567701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
