This century, greenhouse gas emissions such as carbon dioxide, methane and nitrogen oxides must be significantly reduced. Greenhouse gases absorb and emit infrared radiation that contributes to global warming, which can lead to irreversible negative consequences for humans and the environment. Greenhouse gases are caused by the burning of fossil fuels such as crude oil, coal, and natural gas, but livestock farming, and agriculture are also to blame. In addition, deforestation contributes to more greenhouse gases. Of the natural greenhouse gases, water vapor is the main cause of the greenhouse effect, accounting for 90%. The remaining 10% is caused from high to low by carbon dioxide, methane, nitrogen oxides, chlorofluorocarbons, and ozone. In addition, there are industrial greenhouse gases such as fluorinated hydrocarbons, sulphurhexafluoride and nitrogen trifluoride that contribute to the greenhouse effect too. Greenhouse gases are a major cause of climate change, with far-reaching consequences for the welfare of humans and animals. In some regions, extreme weather events like rainfall are more common, while others are associated with more extreme heat waves and droughts. Sea level rise caused by melting ice and an increase in forest fires are undesirable effects of climate change. Countries in low lying areas fear that sea level rise will force their populations to move to the higher lying areas. Climate change is affecting the entire world. An estimated 30-40% o f the carbon dioxide released by the combustion of fossil fuels dissolves into the surface water resulting in an increased concentration of hydrogen ions. This causes the seawater to become more acidic, resulting in a decreasing of carbonate ions. Carbonate ions are an important building block for forming and maintaining calcium carbonate structures of organisms such as oysters, mussels, sea urchins, shallow water corals, deep sea corals and calcareous plankton.

This is a case study which discusses the journey of a successful Ethiopian dairy entrepreneur. It turned out that the inclusiveness of the small holder farmer into the chain with fair incentive sharing mechainsms and guarenteed market access made her chain more efficient, reliable and profitable.

This article aims to supplement the three “golden rules” of rewilding – or three Cs – the Cores, Carnivores, and Corridors – by a fourth C – Compassion, in discussing the case of Oostvaardeplassen in The Netherlands. The cores refer to large, strictly protected ecologically intact areas, carnivores refer to natural predators, and corridors connect passages for fauna movements. We propose a fourth requirement: Compassion. This fourth C would ensure that any active (re)introduction must be in the interests of the individual animals involved. This article briefly explains the history of the Oostvaardeplassen project and leads into a discussion of the scientific (biological requirements of the species, area, and species fit, etc. ) and ethical (animal welfare, ecocentrism, etc.) constraints and opportunities for rewilding. All four Cs, we argue, are absent from Oostvaardeplassen, which can be considered an example of how rewilding should not be undertaken. Against this background, we propose an alternative way forward. https://www.ecos.org.uk/ecos-406-the-golden-rules-of-rewilding-examining-the-case-of-oostvaardersplassen/ LinkedIn: https://www.linkedin.com/in/helenkopnina/
