Britain has one of the most advanced sewer systems in the world, but it is failing to keep pace with growth in population and industrialization. The result is that much of Britain’s wastewater is not treated and discharged into rivers, streams, or seas; instead, it ends up in the ocean where it causes damage to marine life, contaminates drinking water, and can even cause serious health problems for humans.

This situation is not unique to Britain either; almost all countries around the world have experienced similar problems with their sewer systems over the past century as urban areas have grown due to migration and industrialization. But while these problems are global in nature, they do not affect all countries equally. Because of both its size and its distance from major landmasses such as North America and Europe, Britain’s contribution to marine pollution has been relatively low compared to other large, industrialized nations such as France or Germany.


Causes of Sea Pollution in Britain

The main causes of this pollution are leaks in sewer systems and overflows of sewer systems that contain untreated wastewater due to a lack of proper maintenance or design flaws in sewage systems. These two factors are responsible for about 80% of all marine pollution caused by sewage systems. The other 20% comes from industrial effluents that are released into oceans through discharges from factories or other sources.

The main causes of sea pollution in Britain are:

  • Leaks in Sewer System: Leaks occur either due to poor maintenance or due to old pipes that have not been replaced in time. The latter can cause flooding during heavy rain or snowfall.
  • Overflow of Sewer System: Overflowing sewage can lead to floods that contaminate nearby waterways, as well as clog up drains leading to flooding downpours. Overflowing sewage can also pollute the air when it is released into the atmosphere through broken pipes or sewers.
  • Poorly Designed Sewer System: Poorly designed sewers often result in waste being dumped directly into rivers, lakes, and streams instead of being disposed of properly. This often leads to contamination of drinking water and other forms of pollution.


Effects of Sea Pollution in Britain

The effects on marine life include death from diseases that humans cannot contract such as cholera and diphtheria, which can be transmitted through.

1. Damage to Marine Life: The effects of sea pollution on marine life are well known. The damage is caused by the release of harmful chemicals from ships and oil spills. The most obvious effect is that fish, especially those that live near the surface, die as a result of exposure to these chemicals. In addition to this, other forms of pollution can also kill marine life such as plastics, pesticides and other chemicals. These are sometimes harmful to humans too as they can cause cancer or birth defects.

2. Contamination of Drinking Water: In addition to killing marine life, there are also many other serious effects on human health from sea pollution such as cancer, birth defects and kidney failure among other things. Drinking water can be contaminated by oil spills which then means people have no choice but to drink bottled water instead which has an effect on their health too since they are forced to drink bottled water instead of tap water which has been tested for contamination levels before it reaches your tap!

3. Health Risks to Humans: Sea pollution can cause serious health risks for humans. For example, oil spills and other marine debris damaged by ships and boats can carry harmful chemicals into the water, and birds and marine mammals may ingest these materials when they eat contaminated fish or squid. The resulting health problems can include cancer, skin rashes, respiratory problems, reproductive difficulties and even genetic damage (including mutations). Oil spills also affect marine environments by killing sea life and changing the structure of coral reefs. Pollution from fishing vessels also harms marine ecosystems because it leaves behind plastic waste that accumulates on beaches as well as toxic chemicals that accumulate in fish tissues or eggs.


Solutions to Reduce Sea Pollution in Britain

Sea pollution is a growing problem in Britain due to increased human activity over the past few decades. In recent years, there has been an alarming increase in marine litter which consists of plastic debris, sewage waste, oil spills, industrial chemical discharges, illegal dumping of hazardous materials, etc. Such pollutants not only damage marine environments but can also cause serious health problems for humans who come into contact with them or consume seafood contaminated with them. Therefore, it is important to take action against sea pollution in order to protect both ecosystems and human health.

In order to reduce sea pollution in Britain it is important to identify its sources and target them accordingly. The main sources of ocean contamination are human activities such as household waste disposal practices, agricultural run-off from farms, shipping industries, recreational boating etc. There are several methods that can be employed towards reducing this type of water contamination:

1) Increase Recycling and Waste Management: Increasing recycling rates would help reduce the amount of plastic entering the ocean through landfills or other waste disposal sites; introducing laws regarding proper disposal of hazardous materials; improving wastewater treatment systems; providing incentives for businesses who adopt eco-friendly practices; etc. This can all contribute towards reducing ocean contamination from land-based activities.

2) Implement Pollution Control Policies: Governments should enact stricter regulations concerning activities like shipping industries which often release oil into UK waters illegally; set limits on permissible levels of pollutants released by industries near coastal areas; introduce taxes/penalties for polluting companies etc.

3) Invest in Clean Energy Sources: Replacing fossil fuels with renewable energy sources such as solar power or wind turbines would significantly reduce air pollutants entering our oceans via atmosphere deposition thus decreasing overall water contamination levels. Additionally this could help create jobs related to green energy technologies while also helping mitigate climate change caused by burning fossil fuels which negatively affects marine life as well.

4) Promote Education and Awareness: Public education campaigns about the dangers posed by untreated sewage discharge or improper disposal practices can help decrease these types of activities thus lowering overall sea contamination levels; raising awareness among individuals about how their actions affect our oceans can also be beneficial since they may then consider more eco-friendly alternatives when engaging in recreational water sports such as boating.



In conclusion it is clear that tackling sea pollution requires collective effort from governments, businesses as well as individual citizens if we wish to make a significant impact on this global issue. Strategies such as increasing recycling rates; enforcing stricter laws against polluting companies; investing more resources into clean energy projects; and promoting public education about environmental protection measures have all been shown to be effective at reducing ocean contaminants resulting from human activities. It is hoped that further research will continue being conducted so that we may develop better solutions for protecting our oceans from degradation caused by irresponsible behaviour.
