Final answer:
In the 1990s, environmentalism strongly influenced fashion development, leading to an increase in the use of sustainable and eco-friendly materials by brands like Inditex (owner of Zara). This response was driven by consumer demands for environmental accountability and international efforts to combat global environmental challenges.
Step-by-step explanation:
In the 1990s, the fashion industry began to undergo significant changes in response to the rise of environmentalism and public demand for more sustainable practices. In particular, the increased interest in environmental conservation led to the emergence of fashion trends that favored sustainable and eco-friendly materials, leading to the use of sustainable or recycled materials by fashion brands.
Within this context, the environmental movement experienced significant attention increases, thanks in part to prominent incidents and scientific consensus building around issues like oil spills, deforestation, the discovery of the ozone layer hole, and the threat of global warming.
