Before humans inserted themselves into the aquatic food chain, sharks were at the top maintaining balance and playing a crucial role on this earth. For hundreds of millions of years (even before the dinosaurs!) sharks have been shaping our underwater ecosystem and creating a foundation for life in all parts of the sea. Now with 95% of shark populations decreasing everywhere our health and the planet's health is at major risk. Shark livers contain an oil so hydrating and rich all cosmetic that companies want to get their hands on it. This simple substance, also known as squalene, is found all around the world in the form of cosmetics (lotions, anti-wrinkle creams, sunscreen, foundations) and daily off the shelf supplements. With the serious lack of education about what’s in our cosmetics, it makes it scary to think that almost all of us have been absentmindedly plastering on prehistoric predators on our body in the name of beauty.

Biomagnification influences the movement of environmental contaminants and relates to food chains and the transfer of matter in ecosystems, concepts that are found in the Next Generation Science Standards. Consequently, we developed a hands-on, discussion-based activity for the middle school science classroom to demonstrate biomagnification and connect it to food webs and trophic pyramids. Each student represents an aquatic organism, and together students simulate the consumption and excretion processes in an aquatic food chain. This simulation demonstrates how certain environmental contaminants accumulate within organisms and ultimately become concentrated in predators at the top of the food chain.

Diverse Cultures

Globalisation is one of the most powerful worldwide forces transforming society. It dominates today’s world as a major driver of change. Globalisation has brought about an agglomeration of cultures, where diverse cultures not only interact but also sometimes clash. It permeates through all spheres of life including the environment, politics, economy, prosperity, culture, religion, education, and human well-being in societies across the globe. The present “villagization” of the world has greatly affected many African countries in almost all aspects of life. It has done so in both positive and negative ways. With the emergence of a global society, social, cultural, economic, political, technological and environmental events in one part of the world quickly come to be significant for people in other parts of the world. This theoretical paper assesses the impact of globalisation for Africa and its implications to education.

New Framework

Human livelihoods and well-being in almost all regions of the world depend on taxa which are alien. Such taxa also, however, threaten human health, sustainable development, and biodiversity. Since it is not feasible or desirable to control all alien taxa, decision-makers increasingly rely on risk analyses to formalise the best available evidence of the threats posed and whether and how they can be managed. There are a variety of schemes available that consider the risks of alien taxa, but we argue a new framework is needed: 1) given major recent developments in international frameworks dealing with biological invasions (including the scoring of impacts); 2) so that decisions can be made consistently across taxa, regions and realms; 3) to explicitly set out uncertainties; and 4) to provide decision-makers with information both on the risks posed and on what can be done to mitigate or prevent impacts. Any such scheme must also be flexible enough to deal with constraints in capacity and information. Here we present a framework to address these points – the Risk Analysis for Alien Taxa (RAAT). It outlines a series of questions related to an alien taxon’s likelihood of invasion, realised and potential impacts, and options for management. The framework provides a structure for collating relevant data from the published literature to support a robust, transparent process to list alien taxa under legislative and regulatory requirements, with the aim that it can be completed by a trained science graduate within a few days. The framework also provides a defensible process for developing recommendations for the management of assessed taxa. We trialled the framework in South Africa and outline the process followed and some of the taxa assessed to date.
