When discussing with people climate change, there are often discussions about, whether or not this is really happening. To answer this, there is this great tweet:
Every year, 90 billion tonnes of primary materials on average are extracted and used globally, with less than 10% being recycled. This is commercially unsustainable and it can cause significant detrimental impacts on the environment. The circular economy of waste supports the development of new industries and jobs, reduces emissions, and can increase the efficient use of natural resources including energy, water, and other materials.
Fisheries contribute to food security, livelihoods, and human health across the globe. Regrettably, the history of fisheries management worldwide is dotted with more failures than successes (Sarkar et al., 2018). Literature on fisheries management points out case examples of many inefficiencies than successful escapades.
Wetlands are natural regulators of the quantity and quality of water. The common wetlands across the globe include flood plains, freshwater swamps, open coasts, swamp forests, lakes, and peatlands. According to Wu et al. (2018), wetlands are the most diverse and productive ecosystems on the earth; thus, sources of diverse biological communities of invertebrates, birds, and other vertebrates.
The ocean ecosystem is an enormous economic asset and source of livelihood for many people across the globe. Hundreds of millions of people work in mariculture ports, tourism, shipping, offshore energy, and cosmetics, among many other sub-economies supported by the ocean (Stuchtey et al., 2020). Data shows that 90% of the world’s goods are traded across the ocean (Sumaila et al., 2020).
Climate change is caused by human activities that result in the release of carbon dioxide into the atmosphere. Thus, climate change is caused by greenhouse gas accumulation (Hornsey & Fielding, 2020). Although the most cited cause of climate change includes human activities involving burning fossil fuels and deforestation, waste adversely impacts climate change.
One of the most significant tests currently facing humanity is environmental degradation, including desertification, deforestation, climate change, and pollution. Environmental degradation is a serious concern since it contributes to resource scarcity and increases societies’ vulnerability to adverse climate changes. Consequently, it is a major factor fueling human-wildlife conflict and tensions in various communities. According to Choudhary et al. (2015), environmental degradation is the undesirable disturbance to the environment leading to the decline of environmental resources such as soil, air, and water, the ruining of ecosystems, and the extinction of wildlife.
Climate change is the permanent change of weather and temperature in the atmosphere of a place. Human activities contribute the most drivers to climate change such as environmental degradation, burning fossil fuels, and coal. The burning of these materials releases greenhouse gases into the atmosphere leading to climate changes. This text will help understand the worst cases scenario in climate change.
The year 2010 was declared the International Year of Biodiversity by the UN. However, before the declaration, varied media outlets and sources of information had disclosed that most individuals are not aware of what biodiversity entails (Roe, 2019). A recent report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has indicated that more than one million species are facing extinction.
The material recirculation and a move towards recycling with high quality are critical to developing a circular economy; systemic adjustments along value chains are also considered necessary, fundamentally altering production and consumption patterns (Laouar et al., 2019).
