The Truth About Serious Marine Pollution | Let's think about what we can do.

The ocean, which occupies about 70% of the earth, is one of the most important natural resources on earth.つです。

You may also be enjoying the benefits of the sea in many ways, such as eating seafood and going swimming in the summer.ょう。

but by our handsて、Did you know that such pollution of the sea is aggravating at an astonishing rate?うか？

This time, I tried to think about what kind of actual harm is caused by human beings' accelerating marine pollution, and what we can do.ました。

Marine pollution is getting worse

like when you go to the beach、Have you ever seen a large amount of plastic garbage washed up with the waves?？
Mountains of organic waste, floating plastic bags, empty PET bottles, etc., that have flowed in from abroad.いるはず。

But ocean pollution is happening on a much larger scale than just plastic pollution. Here's what we need to know.おくべき、『I listed the facts of marine pollution for each case.た。

ocean plastic waste problem

Most of the garbage that is thrown into the sea and has become a problem is plastic garbageす。
The reason is plastic bags, plastic bottle straws and other plastic containers.など、It is said that unlike other garbage, plastic garbage continues to stay in the sea without being decomposed.す。

Only a small portion of the litter is dumped directly into the sea, and about 80 marine litter gradually flows out of the land through sewers and other routes.流出します。

 

Damage to organisms caused by plastic waste害

Plastic waste drifting in the ocean or washing up on beaches、Swallowed by fish, marine mammals and seabirds, causing serious and life-threatening health hazardsます。

In addition, the swallowed garbage does not decompose naturally, so it will continue to stay in the environment for thousands of years.ります。

ocean acidification

Exhaust fumes from cars, smoke from factory chimneys, etc.、When fossil fuels are burned, sulfur oxides, carbon monoxide, and carbon dioxide are emitted, polluting the atmosphere.れます。

This air pollution is serious in its own way.、Did you know that as the air becomes more polluted, so does the ocean?。

In fact, the ocean absorbs about a quarter of the man-made carbon emitted into the atmosphere, causing ocean acidification.す。
If the pollution continues as it is, the surface water of the ocean after 100 years will beは、It is estimated that the acid concentration will be 1.5 times higher than today. This gives an idea of the seriousness of the problem.ね。

 

As acidification progresses？

As the acidification of the surface water of the sea progresses, the collapse of the marine ecosystem begins、At the same time, it affects the economy of marine seafood.。

Specifically, the survival of bivalves such as oyster clams, which are composed of calcium, is threatened, and the fish and marine mammals that eat these bivalves are exposed to danger.れます。
At the same time, it is speculated that the high acid concentration accelerates the bleaching of coral reefs and affects the organisms that make coral their territory.ます。

sea noise ocean noiseノイズ）

According to one theory, there are about 60,000 commercial ships and container ships that are constantly sailing on the sea.そのCauses sea noise damage due to engine sound and sound wave searchします。

The environment is far from the calm seas that were once ideal for the survival of marine life, and the impact on ecosystems is becoming more serious.いるのです。

 

Ocean noise damage害

Many marine mammals, such as whales and dolphins, as well as fish and other marine animals, primarily use sound to communicate, and use sound to find food and mates.出します。
Sound waves emitted by ships can alarm marine life, preventing them from mating and hunting and feeding, thus threatening their habitat.かします。

This growing problem has begun to attract attention worldwide, and we are working to understand the living conditions of living things and the timing of behavioral breeding and birth migration, and are taking countermeasures such as reviewing the implementation timing of sound wave search.を行なっています。

offshore drilling

Offshore drilling carried out in oil and natural gas exploration and development projects releases countless amounts of gas oil into the seaを放出。
at the same time、The noise generated during excavation also reduces the habitat of marine organisms.小 also causes damage 。

Health damage to organisms

The released gas oil stays in the ocean for decadesけ、Irreversible impacts on delicate marine ecosystems。
The damage caused by offshore drilling is also a global problem because only a small portion of gas and oil can be removed even by advanced sea cleanup work.問題に。

In addition, US President Trump recentlyが、Offshore drilling permits for oil and gas launched on all coastsた This issue has received renewed attention because ofす。

what we can do？

The fate of our oceans requires major measures by the country and government industry units, but not only that, but the daily actions and awareness of each and every one of us are also important.要です。
I summarized what we can do from today to protect the clean and healthy sea.た。

Rethinking household wastewater

There are many things that can be considered in terms of household drainage, but the measures that can be easily started today and have great effects are as follows.通り。

• Do not throw away the tempura oil directly
• Wipe off large oil stains before washing
• Do not throw kitchen waste directly into the drain using a net.い
• Do not overuse shampoo and conditionerい
• Use leftover bath water for washing and cleaningる

Also, depending on the local government, there are some areas that are trying to use used cooking oil as a recovery resource, so let's check the waste oil recovery method of each local government.しょう。

Reduce outflow of plastic waste

Reducing plastic waste is one of the ecological activities that we must be most aware of, as restrictions are becoming stronger not only on an individual basis but also on a company-by-company basis.つです。

Please refer to the following and try from what you can startい。

• Do not pick up shopping bags at supermarket convenience storesい
• Use My Bag Eco Bagる
• Use your own bottles instead of plastic bottlesる
• Use your own bottle and straw at cafes, etc.する
• Food wrap uses reusable wrapる
• don't eat convenience store bento

In particular, the use and significance of disposable straws are becoming a concern, and plastic straws are being abolished one after another in countries around the world.ます。

Why not take this opportunity to reconsider the impact your actions have on the environment?か。

summary

This time, I tried to introduce the worsening damage and what we can do with the theme of marine pollution.した。
The first step in what we can do for the environment is 、Knowing the facts about the environment that are difficult to broadcast in the mediaこと、 And I think that the first thing to do is to practice one by one from what you can do.ます。
