How can we help the tide of biodiversity loss?
We can all do something to help stem the tide of biodiversity loss. We can build birdhouses and bat boxes to attract these high-flying animals. We can plant native flowers and trees in our gardens. Bumblebees are dying off at a terrific rate. We can plant flowers that attract them, giving them a place to pollinate and to rest. Governments can enact legislation keeping bio-sensitive areas off limits or putting caps on greenhouse gas emissions, which fuel global warming [source: Midlothian ].
Why is it important to have a healthy ecosystem?

Why is land development detrimental to the population?
The growing human population and the land development that comes with population growth can be especially detrimental because land conversion and subsequent loss of habitats can affect the stability or continued existence of species.
Why is biodiversity important?
Biodiversity is essential for the sustainable functioning of the agricultural, forest, and natural ecosystems on which humans depend, but human activities, especially the development of natural lands, are causing a species extinction rate of 1,000 to 10,000 times the natural rate.
How do species help the ecosystem?
These roles include capturing and storing energy, providing food, predation, decomposing organic matter, cycling water and nutrients, controlling erosion, controlling pests and climate regulation. Species support biological production and regulation throughout the food chain in a variety of ways, such as adding to soil fertility, pollination, plant growth, predation and waste decomposition. The more diverse an ecosystem is, the more stable it is, the more productive it tends to be, and the better it is able to withstand environmental stress. Biodiversity is essential for sustaining the natural ecosystems on which humans, and all life, depend.

How does human health affect biodiversity?
Scientists have learned a great deal about the regulating services of biodiversity by studying the human health impacts of ecosystem alteration and degradation (Myers et al. 2013). Human-made dams and irrigation projects have been linked to increases in vector-borne diseases such as malaria, leishmaniasis, and schistosomiasis (see Myers et al. 2013 for review). Deforestation and human encroachment into wildlife habitat have been associated with the emergence of several zoonotic diseases, including HIV and ebola (Hahn et al. 2000; Ostfeld 2009). Direct correlations between increased incidence of several infectious diseases, including Lyme, Chagas’, West Nile virus, and hantavirus, and decreasing mammalian or avian species diversity also demonstrate the pro tective, regulating service of biodiversity (see Ostfeld and Keesing 2012 for review).
