Human activities, particularly the release of ozone depleting substances (ODS), have led to the thinning of this protective layer over recent decades. Simultaneously, illegal trade has emerged as a global challenge, giving rise to economic issues, losses of tax revenue, heightened criminal activities, health risks, and environmental hazards. The depletion of the ozone layer, a critical shield protecting the Earth from harmful ultraviolet (UV) radiation, has become a global environmental concern. This paper delves into the legal dimensions surrounding ozone-depleting substances (ODS), their impact on the ozone layer, and the subsequent risk of skin cancer. As countries navigate international agreements, domestic regulations, and enforcement mechanisms, the intricate interplay between legal frameworks and the health implications of ozone layer depletion comes to the forefront. The paper highlights particular instances of illegal trade in ozone depleting substances, drawing from data reported by the parties to the Montreal Protocol. Notably, China stands out as a significant source of contraband ODS, with other countries such as Bulgaria, Lithuania, Poland, and France reporting numerous cases. Analyzing these case instances offers insights into the efficacy of legal frameworks and enforcement measures. The paper offers a comprehensive set of recommendations to strengthen global control and enforcement against the illegal trade of ozone depleting substances. These recommendations span diverse aspects such as production monitoring, customs collaboration, mutual verification, cross-border agreements, public-private partnerships, international cooperation, detection equipment, global regulatory standards, resource allocation, public awareness campaigns, alternative substance development, and controlling the trade at its source. By applying these recommendations and enhancing enforcement measures, we aim to protect the ozone layer and create a healthier and safer world for future generations and achieve sustainable development goals.展开更多

However, most of these resources are illegally obtained and traded in different places within and outside the Ruaha landscape. Due to its illegal nature, most of the important information regarding the trade is poorly documented. Therefore, the current study aimed first, to explore the origin and destination of wildlife products;second, to assess the relationship between hunters and buyers or customers;third, to assess the means used to transport wildlife products;and lastly, to assess who influences people to engage in illegal hunting and trade activities. In addition, we assess the materials used in the exchange of wildlife products. Semi-structured questionnaires and face-to-face interviews were used to collect information from 123 respondents. Social network analysis was used to indicate the origin and destination of wildlife products. The findings show that 70% of wildlife products originate from the Ruaha National Park and MBOMIPA wildlife management areas, with the remaining 30% originating from villages. The majority of respondents (65%) reported transporting wildlife products by foot and bicycle as the primary modes of transportation. Suppliers of wildlife products are reported to have close and long-term relationships with their customers and traders, with most of whom being friends and relatives. We found most poachers to be influenced by their friends and relatives in terms making decision to engage in illegal wildlife trade. In addition, crops like maize and rice were the most popular products used to exchange with wildlife products in the Ruaha landscape. Therefore, in order to combat illegal trade in wildlife products at the local level, alternative income-generating activities need to be promoted accompanied by not only well-funded anti-poaching programmes but also more effective surveillance plans. These should entail the use of advanced techniques and skills, such as wildlife forensics.展开更多

It has brought the negative effects to the sustainable development on global society, economy and ecology, which is also one of the main objectives of international cooperation to combat with. At present, subjects of international law play a decisive role in combating illegal logging and related trade. The subjects of international law generally refer to states, intergovernmental organizations (IGOs) and part of non-governmental organizations (NGOs), which can have an independent international legal personality, enjoy rights and assume obligations of international law. As a responsible big country of the international community and state member of intergovernmental organizations and international treaties of forest resources protection, China ought to fully perform the obligations of international law. In face of illegal logging and related trade around the world, China should rationally tackle with it, resolutely crack down on it, and finally choose the sustainable development strategy based on rule of law.展开更多

Some computational tools were recently developed by researchers based on molecular databases for taxonomy support, forensic identification and conservation purposes. In this study, the DNA Surveillance platform was used to build an online database tool for molecular identification of Brazilian Psittacids using DNA sequences of six mitochondrial genes. To illustrate possible taxonomic issues of the online tool due to interspecific hybridization or unresolved taxonomy, we focused on Amazona aestiva that is considered as one of the most common parrots in Brazil, commonly bred as pets, and considered to be part of a species complex with Amazona ochrocephala from South America. We provide three curated sequence databases, which allow the species identification of individuals or tissue samples of birds of the Psittacidae family using mitochondrial DNA markers, and a comprehensive description of a taxonomic issue involving the A. ochrocephala complex. The results obtained corroborate previous studies suggesting that these species are not reciprocally monophyletic, due to either an ancient hybridization in central Brazil, or, they maybe just are morpho-varieties of the same species. Alternatively, if A. aestiva and A. ochrocephala were considered as sister species, the data could be interpreted either as a result of secondary contact or incipient speciation. Beyond the use of mtDNA for species identification, the high mtDNA haplotype diversity observed in A. aestiva indicates its potential use in discrimination of lineages that could be an important auxiliary tool to certify the captive origin of legally commercialized parrots.展开更多
