Biodiversity is important in maintaining a healthy ecosystem. There are also economic, recreational, and health reasons for promoting biodiversity. What might happen if a certain type of fish dies out of a lake ecosystem? these are the answer choices
* The fish's prey would die out since there are fewer fish to eat them.
* The ecosystem would get stronger since there's less stress on the environment.
*More fishermen would come to the lake to catch the larger fish.
*The fish's predators would be left without a food source and might die out also.

Biodiversity -- the essential variety of life forms on Earth -- continues to decline in every region of the world, significantly reducing nature's capacity to contribute to people's well-being. This alarming trend endangers economies, livelihoods, food security and the quality of life of people everywhere, according to four landmark science reports released today, written by more than 550 leading experts, from over 100 countries.

The result of three years of work, the four regional assessments of biodiversity and ecosystem services cover the Americas, Asia and the Pacific, Africa, as well as Europe and Central Asia -- the entire planet except the poles and the open oceans. The assessment reports were approved by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), in Medellín, Colombia, at the 6th session of its Plenary. IPBES has 129 State Members.

"Biodiversity and nature's contributions to people sound, to many people, academic and far removed from our daily lives," said the Chair of IPBES, Sir Robert Watson, "Nothing could be further from the truth -- they are the bedrock of our food, clean water and energy. They are at the heart not only of our survival, but of our cultures, identities and enjoyment of life. The best available evidence, gathered by the world's leading experts, points us now to a single conclusion: we must act to halt and reverse the unsustainable use of nature -- or risk not only the future we want, but even the lives we currently lead. Fortunately, the evidence also shows that we know how to protect and partially restore our vital natural assets."

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
