America's entry into the World War II led President Roosevelt to pass the “Executive order of 9346” to end Racial Segregation and Discrimination. This order led to the recruitment of skilled labor from America to increase the production of Airplanes. This caused an increase in demand for Engineers, Mathematicians, Craftsmen and Skilled Tradesmen. Therefore they employed Dorothy Johnson Vaughan ( African-American) as the Mathematician in the Newport News, Virginia. She had to face hard conditions during her stay in the New port. There was a separate section for Women Mathematicians at NASA center who performed all the complex calculations. The white society's mind saw the Colored unfit to work at such respectful institutions. Vaughan faced the discrimination in using the dining and the restroom facilities as prohibited by the Jim Crow's law.

Explanation:
The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms. These practices can lead to local extinctions of species and cause other species to migrate to new areas.
We also pollute the air and water, leading to many effects on ecosystems. One major effect of air pollution is the accumulation of greenhouse gases in the atmosphere. These gases trap heat in Earth's atmosphere, warming the planet and causing global climate change.
Introducing species into a new ecosystem can have serious consequences. For example, invasive clam species are dramatically changing the San Francisco bay as they outcompete local populations and enjoy a population explosion without any predators.
Overexploitation reduces population sizes, affecting interactions within an ecosystem. Humans overexploit species by overhunting, overfishing, unsustainable logging, and unregulated pet trade (see image below).
