Do you think the relevance of the International Concept for Sustainable Development has remained (or has increased)? What environmental disasters that have occurred in different countries over the past decade do you know about?

In essence, the concept of sustainable development has become a qualitatively new approach to problems that were previously either not noticed, or were not recognized as important, or were considered not related to the sphere of economic science. The paradigm still dominant in economics is based on certain assumptions about the world, which, while very useful for efficiently allocating resources in the short term, are less accurate and useful in dealing with longer-term, wider and complex problems of sustainable development.
One of the environmental disasters is a significant loss of water in the Aral Sea, the level of which has dropped by 14 meters over 30 years. It divided into two bodies of water, and most of the marine animals, fish and plants became extinct. Part of the Aral Sea has dried up and covered with sand. There is a shortage of drinking water in this area. And although there are attempts to restore the water area, there is a high probability of the death of a huge ecosystem, which will be a loss of a planetary scale.
Another disaster occurred in 1999 at the Zelenchuk hydroelectric power station. In this area, there was a change in rivers, a transfer of water, and the amount of moisture significantly decreased, which contributed to a decrease in populations of flora and fauna, the Elburgan reserve was destroyed.
One of the most global catastrophes is the loss of molecular oxygen contained in water. Scientists have found that over the past half century, this indicator has fallen by more than 2%, which has an extremely negative effect on the state of the waters of the World Ocean. Due to the anthropogenic impact on the hydrosphere, a decrease in the oxygen level in the near-surface water column was observed.
Water pollution by plastic waste has a detrimental effect on the water area. Particles entering the water can change the natural environment of the ocean and have an extremely negative effect on marine life (animals mistake plastic for food and mistakenly swallow chemical elements). Some particles are so small that they cannot be seen. At the same time, they have a serious impact on the ecological state of waters, namely: they provoke a change in climatic conditions, accumulate in the organisms of marine inhabitants (many of which are consumed by humans), and reduce the resource of the ocean.
Environmental safety is the state of protection of the vital environmental interests of a person, first of all, his rights to a clean, healthy, favorable for life natural environment, which arises when a balanced coexistence of the natural environment and human economic activity is achieved, when the level of stress on the natural environment does not exceed its ability to self-healing.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
