Human actions are endangering the well-being of the world’s oceans. Over 80% of marine pollution happens to come through land-based projects. From sea-level rise to coral bleaching, the complete marine ecosystem is swiftly changing.
Needless to talk about Global warming goes on to cause changes in the ocean chemistry and several oceanic means, and it’s threatening various species of those marine animals that can’t cope with the rising temperatures. Keeping all things in mind it is high time that people recognize the challenges ahead and look for the solutions. Thus, here’s presenting 5 of the most significant challenges the oceans face:
- The change in Climate
Climate change is arguably one of the greatest threats to the health of the ocean. It’s turning oceans hotter and sultrier, promoting acidification, besides making it difficult to breathe inside by reducing the dissolved levels of oxygen.
- Plastic pollution
Over 5-trillion pouches of plastic pollution happens to afloat in oceans. Resulting in the growth of Garbage Patch in the Great Pacific. For each pound of the tuna they are taking out, people are putting a couple of pounds of the plastic bags back in.
Nearly one-third of the worldwide fish stock is overfished. The distinct fishes that are once upon a time remarkably abundant, with the likes of bluefin tuna and many others are now getting increasingly endangered. Unreported, unregulated, and illegal fishing may cost the worldwide economy (market) up to 23 billion dollars annually.
- Marine protected regions
Today, just 2 percent of the global ocean is included in fully protected and shielded marine parks. Experts and Scientists suspect that people may be required to protect about 30 percent of oceans to simply provide for the upcoming future of ocean health & ocean wildlife.
- Fisheries subsidies
Each year, governments go on to spend about 35 billion dollars on fisheries subsidies and the large portion of which immediately accelerates harmful overfishing.
- Global warming causes a rise in sea levels, threatening the coastal community centers.
- Several nutrients and pesticides used in agriculture happen to end up in the coastal waters, ending in the depletion of oxygen that goes on to kill shellfish and marine plants.
- Industrial plants and factories release sewage and additional drainage into oceans.
- Air pollution too is liable for almost 1/3rd of nutrients and toxic contaminants that enter oceans and coastal areas.
- Invasive species with the likes of poisonous algae, countless animals, plants, and cholera have gone on to enter harbor waters, disrupted the balance of living organisms.
- Establishing marine parks in large numbers to preserve biodiversity.
- Reducing the practices of destructive fishing like trawling.
- Minimizing the usage of military sonar which may kill or harm whales and several other mammals.
- Installing measures to lessen the no. of fishes caught accidentally.
- Helping fishers to sustain their livelihood via incorporating the conservation efforts.
