The ocean flow in the world is an indispensable force in the earth's ocean, and they carry endless energy and life's rhythm. However, with the advancement of industrialization and modernization, the harmful substances released by human activities have begun to be brought to the world by the world, bringing great danger to our environment and ecosystem. This article will explore the danger of bringing harmful substances around the world and calling on people to take action to protect our ocean and earth.

First of all, as a way of movement in nature, Yangliu is an important part of the earth's ecosystem. They form a complex circular system in different oceans, and distribute energy and material balance globally. However, due to the interference of human activities, we discharged a large number of harmful substances such as industrial wastewater, agricultural pollutants and plastic garbage. These substances were brought to all parts of the world by foreign flow, destroying the balance of marine ecosystems.

A typical example is the problem of plastic garbage. According to statistics, about 8 million tons of plastics enter the ocean each year, and the current flows bring these plastic garbage to the surface and bottom of the ocean. These plastic garbage directly threatened to marine life, and many birds, turtles, whales, and dolphins were mistakenly eaten or wrapped in plastic and died. In addition, plastic waste will be decomposed into tiny particles and entering the marine food chain, which eventually affects human health.

In addition to plastic garbage, industrial and agricultural wastewater is also one of the harmful substances brought to the world. A large number of toxic chemicals, heavy metals and pesticides flow into the ocean through the river, and are quickly spread to all over the world by the ocean flow. These harmful substances not only cause direct damage to marine life, but also accumulate in the organism, which will affect the entire food chain. As part of the food chain, humans ingesting polluting marine life will also face health risks.

In addition, climate change has also affected the movement and distribution of foreign flow, and further exacerbated the spread of harmful substances. Global warming has led to the melting of glaciers and rising sea level, which has changed the marine circulation model and accelerated the speed and intensity of foreign flow. This change makes harmful substances more quickly dispersed to wider sea areas, which in turn affects more biological communities. In addition, climate change has also led to marine acidification, which exacerbates the harm of harmful substances to marine life.

Faced with the danger of bringing harmful substances around the world, we must take positive actions to protect our ocean and earth. First of all, the international community should strengthen cooperation to jointly formulate and implement strict environmental regulations and standards to restrict and reduce the emissions of harmful substances. Government and enterprises should invest in clean technology research and innovation, promote the sustainable development and circular economy, and reduce the negative impact on the environment.

In addition, personal behavior is also crucial. Each of us can start from the small things around us, reduce plastic use, properly handle waste, and participate in the cleaning activities of beaches and rivers. Education and improving public awareness are also the key. People need to understand the harm of harmful substances and the way of motion of foreign flow in order to better protect the ocean and the earth.

Finally, scientific research and monitoring are also an important means to protect the ocean. We need to strengthen the research on foreign flow and marine ecosystems, in -depth understanding of the impact of foreign flow on the spread of harmful substances, and provide scientific basis for formulating more effective protection measures. At the same time, establish a global monitoring network, regularly monitor and evaluate marine pollution, and take measures to respond in time.

In short, it is a serious problem to bring harmful substances to the world, which has a huge threat to marine ecosystems and human health. We must be aware of the impact of our behavior on the environment and take action to protect our ocean and earth. Only through global cooperation and personal efforts can we achieve the goal of sustainable development and ensure that our descendants can continue to enjoy beautiful blue planets.
