Renewable energy sources can help combat climate change, but dietary choices also play a significant role. Opting for plant-based diets or lab-grown food can reduce greenhouse gas emissions from the food system. We highlight the potential of dietary changes and the importance of providing choices instead of mandates （命令）.

Research shows that a global shift towards vegetarian（素食的） diets could cut emissions from food system by over half. Even small changes towards plant-based diets can have a meaningful impact. Substituting conventional food with lab-grown alternatives could prevent 1 degree of future warming. These findings demonstrate the power of dietary changes in addressing climate challenges.

Dietary choices are influenced by factors like culture, religion, and economics. It is unrealistic to expect everyone to become vegetarian immediately. Respecting individual choices is crucial in promoting sustainable diets. By offering information and raising awareness, individuals can make choices according to their needs and values while contributing to collective efforts.

Transforming industrial food production is necessary, but individual choices are still vital. Education and awareness campaigns can inform people about the environmental impact of different dietary choices and empower them to make informed decisions. Combining individual actions with systematic changes can create a powerful force for human health and the planet. Rather than expecting immediate vegetarianism, acknowledging the impact of small changes is important. Gradual shifts towards more sustainable dietary choices, like reducing animal product consumption and increasing vegetable intake, can result in significant environmental benefits when multiplied across populations.

In conclusion, addressing climate change requires multiple approaches, with dietary choices playing a crucial role. Offering choices while recognizing the challenges associated with dietary shifts is essential. By combining personal dietary changes with broader efforts to reshape the food system, we can make substantial progress towards a healthier planet while respecting individual preferences.

T. O. Fuller State Park in Memphis, Tennessee, has been loved for generations and has always been a ground where community has come first. Back in 1938, it was the first park east of the Mississippi river to open for African American visitors. Over 80 years later, the park is continuing its forward-thinking tradition, this time, through a pioneering sustainability project.

A new walking and biking trail has been built through this historic park. Illegally dumped (被丢弃的) tires are not only unpleasant to see, but they’re a dangerous addition to the environment. Rubber, like plastic, is a material that won’t naturally break down. In a place as hot as Tennessee, these dumped tires often begin to melt and release these harmful gasses into the air. Fortunately, the old tires were sent to Patriot Tire Recycling in Bristol, TN, the only facility in the area that can break down tires in an environmentally sound way. There, the collected tires were safely broken down into the crumble(碎屑) rubber that was eventually used to pave the new trail.

TN State Parks explained how the trail’s construction, which has been in development since 2019, was a joint effort. Officials from the Tennessee Department of Environment and Conservation, the Tennessee Department of Transportation, the City of Memphis, Shelby County, and Memphis City Beautiful were all involved in funding this recycling project.

These officials named their initiative the “Tires to Trails” project. Workers from these departments, alongside some 450 volunteers, came together to collect over 24, 000 tires that had been illegally dumped in the area around the park to be recycled.

“This is a perfect example of recycling in full circle, collecting dumped material, then converting it into positive use,” David, a leader of the project, said in a statement.

Tropical rainforests are disappearing at an alarming rate, and according to a new report by Rainforest Foundation Norway, humans are to blame. The world's dependence on coal, farming. soy. palm oil and mining has resulted in two-thirds of Earth's tropical rainforests being completely destroyed, and the remaining ecosystems being put closer to a tipping point.

Tropical rainforests once covered 14.5 million square kilometers of Earth's surface, but now, just one-third of that remains intact. Of the original area tropical rainforests once occupied, 34% is completely gone and 30%is suffering from degradation. All that remains is roughly 9.5 million square kilometers, and45% of that is in a degraded state, the report says.

Researchers blame human consumption for the loss. While agriculture has always been a driving factor of rainforest loss, the report said that energy consumption, international trade and the production of soy and palm oil, logging and mining have been the largest threats over the past century. A significant number of U. S. commodities rely on resources from tropical rainforests. The country heavily relies on palm oil, rubber and cocoa, all of which come from forests around the world. Oftentimes, these resources are harvested from illegally deforested lands.

Tropical rainforests are home to more than half of the Earth's biodiversity and have more carbon in living organisms than any other ecosystem. Along with supporting significant animal life, tropical rainforests are also essential to slowing down global warming. “These highly specialized ecosystems are suffering from constant abuse, through our bottomless appetite for land and resources,” said Anders Krogh, who authored the report. “We expect that upcoming UN climate and biodiversity summits provide specific targets and measures to protect intact tropical rainforests.”

The rescarchers also believe that the loss of tropical rainforests puts the whole world at risk of future pandemics. “Massive deforestation is violating nature's natural virus protection systems.” Krogh said. “The aftermath of COVID-19 should bring rainforest protection to the top of the agenda of all policy makers and world leaders concerned about preventing the outbreak of new pandemics.”
