### More than [1 million species](https://www.ipbes.net/news/Media-Release-Global-Assessment) of plants and animals are at risk of extinction.
That is [25% of the planet's species](https://phys.org/news/2019-04-million-species-extinction-due-humans.html), based on the best estimates. In [Massachusetts alone](https://www.wwlp.com/news/local-news/more-than-300-species-endangered-threatened-in-massachusetts/), there are 432 species that are either considered endangered, threatened or special concern.
While it may seem unimportant if we lose a species here and there, it matters because each species, including humans, plays an important role and relies on other species to survive. The ecosystems become less stable as species go extinct until it eventually collapses. Extinction is irreversible and humans are part of the Earth's web of life. Human land use, particularly for agriculture, is the primary driver of [biodiversity loss](https://www.un.org/en/climatechange/science/climate-issues/biodiversity) wile the climate crisis is increasingly exacerbating the problem. Besides loss of species, loss of animal populations (without them going extinct) is a huge problem, too. In just over 40 years [wildlife populations plummeted by 69%](https://livingplanet.panda.org/en-US/).
##### What Can You Do?
1. Raise awareness to the ecological emergency, e.g. hang ["Lost Animal" Posters](https://drive.google.com/drive/folders/1gH_UnuUdfWkhhSkZ-MBWu4CSuF6CcbpB?usp=share_link) in your neighborhood.
2. Call on your state representative to protect 30% of land and sea by 2030, the international "30x30" target.
3. Protest to stop local habitat loss in your community.

##### Rusty Patched Bumble Bee

The Rusty Patched Bumble Bee was once common in New England and
throughout much of North America. It was an excellent pollinator of
wildflowers, cranberries and fruit trees. Primarily due to introduced
pathogens, this species has lost 87% of its historic range and is now extinct in Massachusetts. Native bees are important pollinators of 75% of native plant species. Causes of native bee population decline also include climate change, pesticides and destruction of habitat.

##### North Atlantic Right Whale
[image:55 align:right size:medium]
The North Atlantic right whale is critically endangered, with less than 450 animals left. Without intervention, they are expected to go extinct by 2040. Whales are threatened by fishing gear entanglement, commercial whaling, seismic testing, and climate change, which shifts their food sources and migration routes.
Whales play a vital role in the health of the oceans by circulating essential nutrients throughout, helping to lock massive amounts of carbon from the atmosphere and provide up to 50% of our oxygen.

##### Black-capped Chickadees
[image:53 align:right size:medium]
The Black-capped Chickadee is the Massachusetts state bird. Even though the Black-capped Chickadee is one of the most common and widespread bird species in the state, they are projected to go extinct in the state by 2050. Because of the effects of the climate crisis on its food source and the collapse of its habitat, their numbers are expected to decline and their distribution shift.
The chickadee is one of the most important pest exterminators of the orchard or forest, because they eat large quantities of insects. The bird also pollinates plants and distributes seeds.

Only about 3,900 tigers remain in the wild, which is 7% of their historical population and less animals than hold captive in the US alone. Tigers are endangered because of hunting, illegal wildlife trade, and habitat loss attributed to climate change. They have lost an estimated 95% of their historical range. As a large predator, tigers play a key role in maintaining the harmony of the ecosystem. By preying on herbivores, tigers help to keep the balance between the prey animals and the forest vegetation which they feed upon.
##### Loggerhead Sea Turtle
[image:56 align:right size:medium]
Sea turtles are endangered because of over-exploitation, habitat loss, and plastic pollution. Climate change harms turtle nesting sites: changes in sand temperatures causes an imbalance in sex distribution and dooms turtles’ ability to mate.
The Loggerhead sea turtle diet helps keep our ocean floor in balance, which contributes to overall ocean health. They are also hosts to an abundance of life: As many as 100 species of animals and plants have been recorded living on one single loggerhead turtle!

##### Monarch butterflies
[image:54 align:right size:medium]
In 20 years, 85% of monarch butterflies have disappeared due to rampant use of pesticides, deforestation leading to habitat loss, and climate change, which causes a disruption of their migration patterns. Monarch butterflies travel every year across Canada, the United States, and Mexico, and spend their lives pollinating our flowers and edible plants like squash supplying one out of three bites that every American eats. Losing the Monarch butterfly and other pollinators means loss of our food supply across North America.

##### Marbled Salamanders
In the eastern United States, there are more salamanders than anywhere else in the world. However, diseases caused by wildlife imports, as well as climate change, droughts and toxins threaten these delicate creatures.
When salamanders die, we know the planet's health is in trouble and that humans are next. Salamanders also protect human life by eating mosquitos and other insects that cause diseases like zika, dengue and malaria.

##### Bald Eagle
[image:58 align:right size:medium]
The bald eagle is an American symbol, the national bird since 1782 and the largest nesting bird of prey in Massachusetts.
Bald eagles were pushed to the brink of extinction due to deforestation, hunting and poisoning with pesticides.
Since the 1980s, MassWildlife and other conservationists, protected and restored the population, so that Bald eagles are no longer on the Federal Endangered Species List. However, they are still species of special concern protected by the Massachusetts Endangered Species Act and the avian flu threatens bald eagle recovery.

##### Polar Bear
[image:59 align:right size:medium]
The loss of sea ice habitat from climate change is the biggest threat to the survival of polar bears. They rely heavily on sea ice for traveling, hunting, resting and mating.
Temperature in the artic are rising twice at fast as anywhere and melting the sea ice. This leaves hungry polar bears with less hunting grounds. Polar bears are already 10% thinner than 30 years ago. Without polar bears to control the seals' population, the number of seals will subsequently increase, threatening the population of crustaceans and fish in the region.
