In the vast oceans of the world, marine ecosystems have borne witness to a growing menace: water pollution. This study focuses on two of the main contributors to this environmental crisis: plastic pollution and overfishing. These interrelated issues have led to a series of devastating effects on marine ecosystems, raising global concerns.

Animals become entangled in them and mistake the smallest fragments for food, which can lead to poisoning and death.

Humans, due to the food chain, also ingest this material, although the consequences for their health have not yet been determined.

In addition, marine litter causes economic losses in sea-dependent sectors and in production in general: only about 5% of the value of plastic packaging remains in the economy. The rest ends up as litter, confirming the need to move towards a more circular approach.]]> 2023-08-19 22:45:51 UTC https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505087 johanyt507 https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505262 The impacts of sewage pollution have been associated with human health, but the detrimental effects of sewage pollution on marine life, and the indirect impacts it has on people, cannot be overlooked. Sewage carries pathogens, nutrients, pollutants and solids into the ocean that can cause coral bleaching and disease and mortality for corals, fish and shellfish. Sewage pollution can also alter ocean temperature, pH, salinity and oxygen levels, disrupting biological processes and physical environments essential to marine life.]]> 2023-08-19 22:47:21 UTC https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505262 johanyt507 https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505482 Catching too many fish can abruptly break the food chain and have multiple effects. Some species may decline in the face of the loss of their food source and others may multiply out of control. Thus, the entire ecosystem must readjust, sometimes with unpredictable consequences. For example, overfishing of bluefin tuna may be one of the reasons why squid populations are increasing, just as it may be contributing to intoxicating algal blooms.]]> 2023-08-19 22:49:14 UTC https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505482 johanyt507 https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505719 Among the main causes of marine pollution are plastic, fertilisers, pesticides and agrochemicals in general.

- Plastic: current estimate is 5.1 mg of polymers.
- Agrochemicals: are the second most important pollutants, including pesticides, herbicides and fertilisers.
- Detergents
- Oils and fats: these are chemicals that are difficult to dissolve in water.
- Organic waste
- Petroleum and petroleum derivatives
- Heavy metals]]> 2023-08-19 22:50:39 UTC https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666505719 johanyt507 https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666506115 Marine Pollution results in a significant decline of marine biodiversity especially in coastal areas in the medium term.

Decrease of biodiversity
Many animals die constantly from poisoning or suffocation.

Eutrophication
This is a very common chemical process in coastal areas, some rivers or aquatic environments highly exposed to pollution by detergents, pesticides, chemical residues, etc.

Diseases
some freshwater sources are the cause of various diseases, sometimes very serious, caused by direct contact with contaminated water or beaches and by the consumption of contaminated fish and molluscs.

Economic impact
 The economic impact can have a significant economic impact on those populations involved in the fishing economy or tourism.]]> 2023-08-19 22:54:14 UTC https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666506115 johanyt507 https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666507461 In conclusion, it is evident that water pollution has a profound impact on marine ecosystems, as examined in this study on plastic pollution and overfishing. The oceans, vital to life on our planet, face significant challenges due to these irresponsible human activities. The ubiquitous presence of plastics in our seas threatens the health of marine life, while overfishing depletes essential fish populations crucial to ecological balance. However, it is heartening to see that awareness about these issues is growing, and steps are being taken to address them. The pursuit of sustainable solutions, such as reducing single-use plastics and promoting responsible fishing practices, is essential to preserving the richness and diversity of marine ecosystems. Through collaboration and commitment, we can reverse the detrimental effects of water pollution and ensure a healthier, more balanced future for our waters and the creatures that inhabit them.]]> 2023-08-19 23:05:20 UTC https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666507461 johanyt507 https://padlet.com/johanyt507/vorofrpeb5s5bfe9/wish/2666508002
