Answer:
Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.
Human activities such as mining, pollution, minerals processing, landfills, etc have an effect on the flow pattern.
<h3>
Effect of pollution</h3>
It should be noted that pollution is usually difficult to control because it is often the result of human infrastructure around a river.
For example, sewage and effluent are discharged into rivers in some areas and this can lower the pH of the water, and hence affect the organisms.
Also, human activities such as mining, pollution, minerals processing, landfills, impact negatively on the quality of water and the flow pattern in the upper reaches of the blood river in Limpopo.

I’m pretty sure you just add AB to BC, since they are all points on a line, those two segments add together to get the value of AC. Therefore, 12+16= 28, so AC=28
