But now, it\u2019s imperiled by forces the monarchs themselves cannot control. The reduction in the area of forest they occupied this year \u2013most probably due to the high mortality caused by storms and cold weather last year\u2014 is a clear reminder for the three countries that they must step up actions to protect breeding, feeding and migratory habitat.&#8221; Mr. Vidal continued, &#8220;We\u00a0cannot control the climate, but we can do much better in eradicating illegal logging in the reserve and tackling habitat loss in the U.S. and Canada. But, even if Mexico&#8217;s overwintering sites never lose another tree, without food and habitat along the migration routes the forests will soon bid farewell to their final orange and black-winged tenant.&#8221;<\/p>\n<p>Monarch butterflies are one of many important pollinator species that have experienced drastic declines in recent years. Along with threats from glyphosate use and habitat loss, the <a href=\"http:\/\/beyondpesticides.org\/dailynewsblog\/2015\/02\/new-research-links-bee-killing-insecticide-to-monarch-butterfly-deaths\/\">use of neonoicotinoid pesticides<\/a> has also been linked to monarch declines. In addition to monarch butterflies, honey bees and wild bees have also been experiencing a drastic <a href=\"https:\/\/www.beyondpesticides.org\/pollinators\/nolongeraBIGmystery.pdf\"><strong>decline in numbers<\/strong><\/a>\u00a0\u00a0that has been linked to the prevalent use of neonicotinoids. A <a href=\"https:\/\/www.beyondpesticides.org\/dailynewsblog\/?p=9151\">recent report<\/a> issued by the European Food Safety Authority (EFSA) states that certain neonicotinoid insecticides pose an unacceptable hazard to honey bees. The EFSA report concludes that systemic contamination of neonicotinoid-treated crops, neonicotinoid dust exposure, and contaminated nectar and pollen contributes to declines in honey bees and weakens their hives. With one in three bites of food reliant on bees and other insects for pollination, the decline of honey bees and other pollinators due to pesticides and other man-made causes demands immediate action. Beyond Pesticides has <a href=\"https:\/\/org2.salsalabs.com\/o\/7106\/p\/dia\/action3\/common\/public\/index.sjs?action_KEY=20676\">petitioned<\/a> the U.S. Environmental Protection Agency (EPA) to suspend the use of bee toxic chemicals pending a full review of their effects on pollinators.<\/p>\n<p>Critical to the survival of monarchs, other pollinators, and organisms essential to ecological balance is the large-scale\u00a0adoption of organic farming practices. Beyond Pesticides supports\u00a0<a href=\"https:\/\/www.beyondpesticides.org\/organicfood\/index.php\"><strong>organic agriculture<\/strong><\/a>\u00a0\u00a0as effecting good land stewardship and a reduction in hazardous chemical exposures for workers on the farm. The pesticide reform movement, citing pesticide problems associated with chemical agriculture, from groundwater contamination and runoff to drift, views organic as the solution to a serious public health and environmental threat.<\/p>\n<p>On a personal level, <a href=\"https:\/\/www.beyondpesticides.org\/pollinators\/protect\/steps.php\"><strong>several steps<\/strong><\/a>\u00a0may be taken to attract beneficial insects like monarchs and protect backyard habitats.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides. Beyond Pesticides believes that people must have a voice in decisions which affect them directly.","sameAs":["https:\/\/www.beyondpesticides.org","https:\/\/www.facebook.com\/beyondpesticides\/","https:\/\/www.instagram.com\/beyondpesticides\/","https:\/\/www.linkedin.com\/company\/beyond-pesticides\/","https:\/\/x.com\/ByondPesticides","https:\/\/www.youtube.com\/user\/bpncamp\/"],"url":"https:\/\/beyondpesticides.org\/dailynewsblog\/author\/beyond-pesticides\/"}]}},"_links":{"self":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19995","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/comments?post=19995"}],"version-history":[{"count":4,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19995\/revisions"}],"predecessor-version":[{"id":20000,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/19995\/revisions\/20000"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=19995"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=19995"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=19995"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
