Answer:
Rising ocean temperatures will influence reef species to move to another area that has cooler areas.
Pollution will create dead zones where there are little to no wildlife. Material pollution like plastic will also kill marine life.
Human interference can affect the ecosystems by polluting, overfishing, and destroying coral.
Explanation:
Some marine life are not suitable to warm temperatures, and this will cause them to move to cooler ones, disrupting the normal balance the ecosystem once had.
Pollution from fertilizer runoff and others can deplete the oxygen in the water, and animals like turtles believe plastic is food and will kill them by destroying internal organs and blocking intestines.
Humans pollute and overfish, and this throws the ecosystems off balance because it will create dead zones and will significantly decrease the amount of wildlife there. Humans also destroy coral, which will make reefs die and destroy habitats for wildlife.

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.
