In today's increasingly serious environmental problems, it has become an important task for China to solve environmental problems and realize the sustainable development of human, nature and society. Social development is no longer simply pursuing economic growth, but pursuing the harmonious development between man and nature. This urges people to think and explore how to find solutions to environmental problems. In this process of thinking, people began to study the knowledge related to the environment in the history of human thought, explore the roots of environmental pollution and ecological destruction, and thus seek ways and countermeasures to protect and manage the environment.

Marxism contains rich environmental philosophy. Studying Marxist environmental thought is of great guiding significance for us to solve environmental problems. This paper analyzes the causes of environmental problems and some problems faced by environmental protection in China from the viewpoint of Marxist environmental thought: adhere to the principle of subjectivity and correctly treat the relationship between man and nature from the viewpoint of materialist dialectics.

Nowadays, the modernization of cities and the continuous improvement of people's living standards are the results of human beings transforming the natural and objective world through labor practice. China's backwardness from poverty in the early days of the founding of the People's Republic of China to a well-off life today is also the result of the labor practice of all the people in China. Marxism tells us that practice is actually that we actively transform the world, while animals can only passively adapt to the environment. In this process, Marx thinks that man is the subject and nature is the object. The rapid development of China is bound to be accompanied by the transformation of nature and the occupation of natural resources. In this process, China did not correctly understand the relationship between man and nature at first, but continued to develop the economy, meet people's material and cultural needs, get people out of poverty, and finally achieve * * * and prosperity, but ignored the responsibility of protecting nature while transforming nature and occupying natural resources. It has caused serious environmental problems and seriously restricted China's economic and social development. Therefore, we should protect nature, protect the ecological environment and protect our human living environment.

Scientific Outlook on Development summed up the successful experience of China's reform, opening up and modernization in the past 20 years, absorbed the experience and lessons of other countries in the development process, revealed the objective laws of economic and social development, and embodied our party's new understanding of development issues. The establishment and implementation of Scientific Outlook on Development is closely related to the protection of ecological environment. At present, how to protect the ecological environment in Scientific Outlook on Development is a very important and urgent problem.

First, the relationship between environmental protection and economic growth.

First of all, a good ecological environment and sufficient natural resources are the basis and conditions for economic growth.

Secondly, insufficient economic growth or improper growth mode is an important cause of environmental pollution, resource depletion and ecological destruction.

Third, economic development should be sustainable. We should consider not only the development needs of contemporary people, but also future generations.

It is our historical responsibility to meet the needs of development and leave good environmental conditions for future generations.

Fourth, environmental problems are brought about by development and can only be solved through development. Without necessary economic growth and lack of environmental improvement conditions and financial support, it is difficult to protect the environment.

In a word, protecting and improving the environment should be one of the purposes of economic development. The solution to today's environmental problems is not whether to develop, but what is the purpose of development and how to develop it.

Second, the current major environmental problems in China and their impact on development

Serious environmental pollution and ecological destruction have negative effects on economic and social development. The first is huge economic losses.

Secondly, environmental pollution affects people's health and has become a social problem that people pay more and more attention to.

Third, environmental problems affect social stability.

Third, strengthen ecological environment protection and strive to achieve sustainable development.

1. To solve environmental problems, we should start with economic development.

2. Adhere to the people-oriented principle and safeguard the people's environmental rights and interests.

3. Relying on scientific and technological progress to realize the leap-forward development of environmental protection.

4. Do a good job in corporate environmental protection.

5. Increase government investment in environmental protection.

6. International cooperation promotes global sustainable development.

In a word, the contradiction between economic development and environmental protection is both antagonistic and unified. Contradictions are not only universal but also objective. Adult contradictions are universal and objective, dare to admit and expose contradictions, insist on analyzing and solving problems in two ways, and insist on dichotomy and dualism. Establish the concept of coordinated development of economy, population, resources and environment, seize the development opportunity, and realize the comprehensive unity of economic, social and environmental benefits.
