Give reason why Environmental problems are just as real, just as controversial and just as in need of intelligent solutions which is possible through educated and dedicated environmentalists. ​

Answers

Answer:

Answer:

Environmentalism or environmental rights is a broad philosophy, ideology, and social movement regarding concerns for environmental protection and improvement of the health of the environment, particularly as the measure for this health seeks to incorporate the impact of changes to the environment on humans, animals, plants and non-living matter. While environmentalism focuses more on the environmental and nature-related aspects of green ideology and politics, ecology combines the ideology of social ecology and environmentalism.

Environmentalism advocates the preservation, restoration and improvement of the natural environment and critical earth system elements or processes such as the climate, and may be referred to as a movement to control pollution or protect plant and animal diversity.[1] For this reason, concepts such as a land ethic, environmental ethics, biodiversity, ecology, and the biophilia hypothesis figure predominantly.

At its crux, environmentalism is an attempt to balance relations between humans and the various natural systems on which they depend in such a way that all the components are accorded a proper degree of sustainability. The exact measures and outcomes of this balance is controversial and there are many different ways for environmental concerns to be expressed in practice. Environmentalism and environmental concerns are often represented by the colour green,[2] but this association has been appropriated by the marketing industries for the tactic known as greenwashing.

Environmentalism is opposed by anti-environmentalism, which says that the Earth is less fragile than some environmentalists maintain, and portrays environmentalism as overreacting to the human contribution to climate change or opposing human advancement.

Thank you dear for marking me as brainlist.

Environmental problems are indeed just as real, controversial, and in need of intelligent solutions as any other societal issue. Here are several reasons why:

Global Impact: Environmental problems have far-reaching consequences that transcend borders and affect the entire planet. Interconnectedness: The environment is interconnected with various aspects of human life, including social, economic, and cultural factors. Controversy and Conflicting Interests: Environmental problems often involve conflicting interests, such as economic development versus conservation, corporate interests versus public health, or short-term gains versus long-term sustainability.
