Yes, pollution and development go together. The principal concern is the development but with pollution abatement.
Yes, there is a conflict between economic growth and environmental protection.
Look at my blog post emphasizing the acceptance of Green Hydrogen, which seems to be influenced by economic growth rather than environmental protection.
The relationships between pollution and economic development are complex with several possible feedback loops that are predicated on drivers and consequences of economic growth, ecosystem resilience and the ultimate reliance of financial capital on nature. There is a close relationship between the environment and development: The environment is the locality and the object of development, while development is the cause of environmental changes. This is because the aggravation of environmental pollution can not only reduce people's subjective well-being, affecting their quality of daily life, but also indirectly reduce employees' work efficiency, which has a negative impact on the creation of economic value. Deforestation resulting from economic development damages soil and makes areas more prone to drought and loss of biodiversity. Economic growth leads to resource depletion and loss of biodiversity. This could harm future 'carrying capacity of ecological systems' for the economy. The struggle between development and environmental conservation stems from nations' ambition to become industrialized and secure their place as economically developed nations. It is evident that development and environmental protection are inextricably linked, and that one is the natural polar opposite of the other. Pollution stunts economic growth, exacerbates poverty and inequality in both urban and rural areas, and significantly contributes to climate change. Poor people, who cannot afford to protect themselves from the negative impacts of pollution, end up suffering the most. The environmental impact of economic growth includes the increased consumption of non-renewable resources, higher levels of pollution, global warming and the potential loss of environmental habitats. However, not all forms of economic growth cause damage to the environment. Pollution level would increase during the early stages of economic development and will reach the maximum. The maximum level of pollution is referred to as the turning point after which it begins to decline as the country gains adequate resources to tackle the pollution problem.There is a constant conflict between economics and the environment includes large-scale problems like climate change, overpopulation, resource depletion, and pollution. The solution is to find a balance between these two fields of knowledge.
