In the next decade or so, the sea will inundate some of the bottom coasts, and in a few decades, including most of the Netherlands, Manhattan and other areas will be submerged.
Further Material: 1: On Global Environmental Issues:
1.Global environmental problems, also known as international environmental problems or global environmental problems, refer to global environmental pollution and ecological balance destruction that transcend the national boundaries and jurisdictions of sovereign states. Its meaning is:
First, there are some environmental problems that are prevalent on the planet. Environmental problems in different countries and regions are universal and common in nature, such as climate change, ozone layer depletion, water shortage, and biodiversity loss. Second, although it is an environmental problem in some countries and regions, its impacts and harms have transnational and trans-regional consequences, such as acid rain, marine pollution, transboundary movement of toxic chemicals and hazardous wastes, etc. At present, the environmental problems that have attracted global attention mainly include:
Global climate change, acid rain pollution, ozone layer depletion, transboundary movement and spread of toxic and harmful chemicals and wastes, sharp decline in biodiversity, marine pollution, etc. There are also common ecological and environmental problems in developing countries, such as water pollution and water shortage, land degradation, desertification, soil erosion, and forest reduction.
2.Although global environmental problems are the continuation and development of environmental problems in various countries and regions, they are not the sum of environmental problems in various countries or regions, so they show their unique characteristics as a whole
2. Although environmental problems occurred all over the world in the past, the scope of their impact, the objects of harm or the consequences were mainly concentrated near the pollution source or in the specific ecological environment, and the space for their impact was limited and the scope of global environmental problems was expanded to the whole world. This is because:
1. Some environmental pollution has transnational and cross-regional mobility: for example, some international rivers, pollution caused by upstream countries may endanger downstream countries; Acid rain caused by air pollution in some countries may fall to other countries.
2. Some contemporary environmental problems, such as climate warming and the hole in the ozone layer, have a global impact, and their consequences are also global.
3. Many contemporary environmental problems involve high-altitude and oceanic and even outer space, and the scale of their impact is far from being comparable to that of agricultural societies and general environmental problems in the early stage of industrialization, and has the characteristics of large-scale and global.

Anonymous users2024-02-14How has the global environment changed in recent years, and what will happen in the future?
Pro, changes in the environment in recent years: environmental problems around the world have become more and more serious. For example, the air polluted by cars affects people's breathing, factories release polluting gases, trees are cut down in the mountains, and sewage is constantly discharged into rivers.
In addition, no matter where we go, we can see garbage thrown away everywhere. In fact, pollution is threatening our very existence. The human environment is getting worse and worse, the resources and energy resources are in short supply, climate change is becoming more and more abnormal, geological disasters are becoming more frequent, and the earth is warming year by year.
What will happen in the future: a hole in the ozone layer over Antarctica, a warming climate, an increase in average temperatures, and melting ice at the poles, causing sea levels to rise. In the next decade or so, the sea will inundate some of the bottom coasts, and in a few decades, slow seepage will include most of the Netherlands, Manhattan and other areas will be submerged.
In general, environmental pollution can be the result of human activities, natural activities, or a combination of both. For example, volcanic eruptions emit a large amount of dust and sulfur dioxide and other harmful gases into the atmosphere, which also causes pollution of the atmospheric environment. But usually, environmental pollution is more caused by human activities, especially socio-economic activities. >>>More

My father, an old doctor, has worked at the grassroots level for decades, and his work is outstanding, and my medical career has been greatly influenced by my father. My father said that he could see any kind of disease, but he was afraid of midwifery, and he couldn't handle obstetrics, so I studied maternal and child medicine and became a midwife. >>>More
