We as Marine Scientists, we deal with marine pollution

Water is Work

 “No water no jobs” is the sentence we can read in the UN World Water Day campaign. This year’s purpose is to highlight the links between water, jobs and sustainable developments. Indeed, water  is essential for life,  but it is also essential for jobs.

 One and a half billion people (half of the world’s workers) work in water related sectors.   According to the report released on the 22th of march, the population in Earth  will grow a 33% between 2011 and 2050 (from 7 billion to 9,3 billion). Due to increasing population,one of  the main issues will be the global food security.


Food security: When all people at all times have access to sufficient safe, nutritious food to maintain a healthy and active life.


One of the main threats to freshwater is global warming. In fact, for every degree gain in temperature, almost 7% of the population is exposed to a reduction of freshwater. The main sectors threatened by global warming  are the energy and agricultural sectors. This is due to an increase in population which will derive in an increase in demand.

We as Marine Scientists, we deal with marine pollution


The common and general  idea for a long time now, has been :no matter how much trash and chemicals humans dump into the ocean, the effects will be negligible. Yet

marine pollution is a big issue, one of the most difficult matter to address and to resolve, hard to solve that problem.

Says Els Vermeulen, post-doctoral fellow at the university of Pretoria and Co-founder of Sea Search Africa.

Pollution can be described as the introduction of harmful contaminants outside the norm for a given ecosystem. Thus, pollution refers to pesticides, herbicides, chemical fertilizers, detergents, oil sewage, plastics and other solids. Marine pollution affects not only the marine environment and our health (pollutants collected at the ocean’s depths are consumed by small marine organism then introduced into the global food chain) but also the working conditions of marine scientists.

Els Vermeulen stated

If you have bad water quality, it can also affect your job and the results obtained  on the research

We asked her if her job would be threatened in the case there was even a bigger change in water quality due to pollution. And she replied that the job would not necessarily change but the kind of conservation focus would. 3

Furthemore, pollution is not always visible as noise pollution is also a big issue in water. The Sea Search group is currently conducting several studies on the impact of noise on dolphins and whales in southern Africa.
