A potential remedy to the problem of some 鈥渇orever chemicals鈥� lies in two naturally occurring soil bacteria. Scientists at the University of California, Riverside found that the bacteria are able to cleave the strong carbon-chlorine bonds of a subgroup of per- and poly-fluoroalkyl substances, or PFAS, which then leads to further breakdown of the chemicals.

Since the 1940s, PFAS compounds have been used in consumer products for their resistance to water, heat, and lipids. Evidence of their negative health and environmental impacts has accumulated since.

In March the Environmental Protection Agency proposed its first national drinking-water standard to limit six specific PFAS. This past January, five European countries took the first step toward banning all PFAS, which if passed would be the largest ever substances ban in Europe.

While the two bacteria can鈥檛 address PFAS that don鈥檛 contain chlorine, 鈥渘ow, we know who they are,鈥� said Professor Yujie Men, a co-author of the paper. 鈥淲e can use the pure cultures to further understand the degradation mechanisms, which enzymes are involved, and whether we can manipulate or modify those to make them better.鈥�

2. Caribbean

After three court decisions across the Caribbean in the past year, only six countries in the Americas still criminalize same-sex relations. While the laws promising lengthy imprisonment are rarely enforced, advocates say that their persistence exposes LGBTQ+ people to discrimination and violence, and that the human right to privacy is violated by these laws. In December, Barbados became the latest country in the region to make reforms.

The United Kingdom had decriminalized sodomy by 1982, but its former colonies bore its earlier influence even after independence. Legal cases are pending in Dominica, Grenada, Jamaica, St. Lucia, and St. Vincent and the Grenadines. In the region, only Guyana has no LGBTQ+ rights challenge in progress. 聽

Nearly a decade ago, activists began working on the Caribbean鈥檚 anti-LGBTQ+ laws. In 2016, the Supreme Court in Belize ruled unconstitutional the criminal code against same-sex relations. 鈥淭hat created a starting point for the entire region,鈥� said T茅a Braun of Human Dignity Trust. 鈥淚t demonstrated that the courts are an effective vehicle for challenging this type of discriminatory law.鈥�

3. Spain

A village in Spain is adapting to climate change by fostering a culture of innovation. About 8,000 people live in La Almunia de Do帽a Godina, which was named a 鈥渃ity of science and innovation鈥� in 2022 by the Spanish government.

The village has its own public university focused on engineering and research. One recent graduate had designed a machine that could make wastewater treatment more efficient. He now works for the water plant. 鈥淟ife is better in a village if you are able to find a job with a high level of satisfaction,鈥� says Jes煤s Sancho.

A local startup converts methane from hen droppings into biomethane that could power farm vehicles. Hen droppings are also redistributed for use as fertilizer.

When electricity prices were driven up by the war in Ukraine, fruit farmers began installing solar-powered pumps to water their orchards. Inspired by the farmers, Mayor Gracia Blanco initiated a communal solar system atop municipal roofs so families lacking space to install their own panels could buy into a solar grid. And at the local preschool, the underfloor heating is solar powered. 鈥淭he children like to touch the floor and lie down,鈥� says teacher Mar铆a Jos茅 D铆az.

4. Indonesia

Indonesia鈥檚 Indigenous peoples and local communities (IPLCs) will get millions of dollars in funding to address climate change. The $3 million Nusantara Fund launched in May, with the goal of raising $20 million over the first five years to finance locally driven climate initiatives.

The fund is backed by international philanthropies, including the Ford Foundation. It will be managed in partnership with three organizations on the ground: AMAN, which represents 20 million Indonesians; KPA, the country鈥檚 largest agrarian reform organization; and WALHI, Indonesia鈥檚 largest environmental group. They will prioritize establishing education centers, mapping Indigenous land, registering land ownership rights, restoring degraded regions, and developing the economy based on sustainable use of natural resources.

In one of eight villages served by the fund鈥檚 pilot phase, coffee farmer Asep Rohimat has switched to organic fertilizers, boosted yields, and found higher prices for his arabica beans. 聽

The United Nations estimates 80% of the world鈥檚 biodiversity is managed and protected by IPLCs 鈥� yet they receive less than 1% of foreign aid to address climate change. Indonesia is one of 17 species-rich 鈥渕egadiverse鈥� countries, which are considered vital to protect.

World

Global suicide rates dropped by a third in the last three decades. Large declines occurred in India (15%) and China (over 60%) 鈥� the two most populous countries.

Experts attribute much of the decline to 鈥渕eans restriction鈥�: reduced access to suicide methods. In China, for instance, economic shifts meant large numbers of people moved into cities and away from rural communities, where pesticides 鈥� the leading method of death by suicide in China 鈥� were readily available. With pesticides no longer on hand, the suicide rate dropped.

Sri Lanka, which had the world鈥檚 highest rate of suicide in 1995, saw a 70% reduction when pesticides were restricted in that country.
In the United States, however, rates have jumped, up 35% from 2000 to 2018; over half of all suicides in the U.S. involve a firearm.
Reducing the suicide mortality rate is a U.N. Sustainable Development Goal, and suicide remains a major pubic health concern worldwide. Since economic disadvantage generally puts people at greater risk of suicide, some health policy experts recommend a focus on reducing socioeconomic inequalities, as well as addressing root causes for individuals.
