Chesapeake Bay is an estuary in the U.S. states of Maryland and Virginia. Efforts have been made in Chesapeake Bay to improve water quality, the Bay improved slightly in 2010, after an investment of about $ 15 million in cleanup. Long Island Sound also suffers from pollution and has had strategies to reduce the amount of nitrogen that enters, such as the state of New York and Connecticut.

Finally Puget Sound has received collaboration from different sectors using science and research thanks to the Department Ecology State of Washington.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
