“The CO2 problem” has traditionally been understood as the fact that excessive CO2 produces global warming. But near the end of the 20th century, scientists started talking about a second CO2 problem, “ocean acidification”. Ocean acidification results from the fact that about 30 percent of our CO2 emissions have been absorbed by the ocean. This absorption keeps down the warming of the atmosphere that would otherwise be produced by these emissions. Ocean acidification involves the ocean’s pH, changes in which make the water become either more alkaline or more acidic. Tests have shown that “for more than 600,000 years the … Continue reading →
The sheer volume of plastic waste generated coupled with energy and material resources required for production, as well as emissions resulting from these processes paint a grim picture of the environmental havoc created by plastic bags. Single-use plastic bags are a huge threat to the environment as an estimated 1 trillion such bags are consumed worldwide every year. Plastic bags are notorious for their interference in natural ecosystems and for causing the death of aquatic organisms, animals and birds. In 2006, The United Nations Environment Programme estimated that there are 46,000 pieces of plastic litter floating in every square mile … Continue reading →
Ecosystems are permanently challenged with the abundant release of toxic compounds into the environment due to a wide range of anthropogenic activities. Apparently, contamination with oil spills and oily waste disposal are a major global concern since it’s extensively damaging the biodiversity, threatening the public health and has severe ecological and socioeconomic consequences. For example, in 1989, thousands metric tons spell of crude oil in Alaska, led to a massive loss in the marine life as well as several long-term environmental impact. Minor oil spills and non-point oil contamination are no less threats to public health, biodiversity and environment. Awareness of … Continue reading →
Desalination is a water treatment process that separates salts from saline water to produce potable water. The desalination process uses large amount of energy to produce pure water from salt water source. Salt water is fed into the process, and the result is an output stream of pure water and another stream of waster with high salt concentration. Desalination techniques are mainly classified into two types: Processes based on physical change in the state of the water, and Processes using a membrane that employ the concept of filtration. There are more than 15,000 industrial-scale desalination units worldwide, with combined capacity exceeding … Continue reading →
With the advent of December, many festivities, celebrations and seasonal parties are planned globally. These events require feverish shopping leading to usage and wastage of more resources. In addition, December is also famous for the shopping mania that grips people from all walks of life. ‘Shopping’ is certainly one of the most famous ‘indoor sport’ being practiced equally by people of developed and developing countries depending on their life style and budget and is mainy being done by the female gender. ‘Going green’ is a way forward for all of us as it is a life style change including improving our … Continue reading →
Our environment is more than trees, water, land, and air. It is a sense of peace, an understanding of our place in our society. It sustains our satisfaction in life and our interest in caring for the life around us. Recognizing the sustaining forces that make up our environment sometimes requires a time of deep introspection. Few practices in the human repertoire can guide us to deep introspection like the profound practice of fasting in the holy month of Ramadan. For one full month in every year, fasting is required for Muslims all over the world. The day-long fasting process in … Continue reading →
With rising awareness of global warming and effects of emissions on the environment, corporates and individuals alike are rising to tackle environmental issues. Carbon footprinting, the first step to reduce carbon emissions, is the total set of greenhouse gas emissions caused directly or indirectly by an individual, organization, event or product. The main reason for calculating a carbon footprint is to inform decisions on how to reduce the climate change impact of a company, service or product. Carbon footprints are measured by undertaking a greenhouse gas assessment. Once the size of a carbon footprint is known, a strategy can be … Continue reading →
Eidul Adha, like other religious festivals, often has a major impact on the environmental resources. Extra food, drinks and clothes are made, used and consumed which results in a major environmental footprint. The celebrations and festivity are often extravagant and cause pollution of different forms. The day starts with the special prayers whereby men, women and children gather to offer prayers. The site of praying after the ritual is often plagued by litter, rubbish and waste scattered all over the place and even blowing in the air and migrating to nearby safe heavens for unaesthetic and unhygienic accumulations. Muslims on Eid … Continue reading →
The current state of environmental custodianship in Qatar leaves much to be desired from the national government and other institutions that publicly endorse initiatives with much fan-fare but do not commit to sustained action. My previous piece titled “Environmental Initiatives in Middle East – Challenges and Remedies” illuminated some of these gaps, but did not provide a detailed description of what underpins this trend and possible solutions might look like. Thus, this article seeks to delve deeper into how state institutions and civil society in Qatar may be able to work cooperatively in staving off further environmental degradation, especially with … Continue reading →
Wetlands are wonderful for numerous reasons but these wonders weren’t always known to man and it was often common to overlook the importance of this distinct ecosystem. The mention of a wetland used to bring to mind images of murky, mosquito-riddled swamps or unused lands that needed to be developed into a space which would be more useful to humankind. Wetlands were grossly undervalued which led to loss of many and provoked the Convention on Wetlands to be signed in Ramsar, Iran in 1971. The Ramsar Convention still serves as an international wetland conservation movement and currently holds over 160 nation … Continue reading →
Environment is a global public good and a prerequisite for the enjoyment of human rights. Environment has no respect for international boundaries and borders, and belongs to all countries and peoples. However the capacity of environment is limited and a common issue for the entire mankind is to conserve this limited global environment so that all people on earth (and coming generations) can enjoy a healthy life. Right to Healthy Environment The right to a healthy and sustainable environment is getting increasing importance in the light of climate change concerns. With fast-changing geo-political situations and ever-increasing conflicts, conservation of the … Continue reading →
The rapid deployment of 3D printing is one of the most exciting developments since the appearance of the smart phone. This is technology with some serious potential to change how and where goods are manufactured, transforming supply chains. The New Scientist has gone so far as to herald 3D printing, also known as additive manufacturing, as ushering in a second industrial revolution. But is anyone thinking about how what this new development means for the waste sector? Whilst the technology is already being put to some dubious uses, the ability to manufacture pretty much anything wherever and whenever it’s needed is certainly appealing. Interest isn’t … Continue reading →
