⚡ 1. AI's Energy Consumption Projected to Surpass Bitcoin by End of 2025

Source: The Verge

A recent study by researcher Alex de Vries-Gao from Vrije Universiteit Amsterdam indicates that Artificial Intelligence (AI) is on track to consume more electricity than Bitcoin mining by the end of 2025. The surge in energy demand is attributed to the rapid expansion of large, resource-intensive AI models and the proliferation of data centers, particularly in the U.S. This trend raises significant environmental concerns, emphasizing the need for greater transparency in AI energy usage and a shift towards more sustainable AI development practices.

🧱 2. MIT Develops AI Framework to Enhance Sustainable Concrete Production

Researchers at MIT have introduced an Artificial Intelligence (AI) framework designed to identify alternative materials for concrete production, aiming to reduce the environmental impact of cement manufacturing. By analyzing over a million rock samples and scientific literature, the AI system suggests incorporating materials like ceramics, mining byproducts, and demolished construction waste into concrete mixes. This approach not only promotes a circular economy but also offers a practical solution to lower carbon emissions in the construction industry.

🌊 3. Global Leaders to Address Ocean Emergency at UN Conference

In May 2025, the United Nations announced the upcoming Third U.N. Ocean Conference, set to take place in Nice, France, from June 9 to 13. Co-hosted by France and Costa Rica, the conference aims to tackle what the UN describes as a global emergency affecting the world's oceans, including rising temperatures, plastic pollution, and overexploitation of marine resources. Over 60 world leaders, 4,000 government officials, and 6,000 civil society participants are expected to attend. Key goals include accelerating action to sustainably use and protect ocean resources, securing $100 billion in commitments, and promoting the ratification of the 2023 high seas biodiversity treaty. The conference will adopt a declaration recognizing the oceans' crucial role in sustaining life and emphasizing the slow progress on climate change, biodiversity loss, and pollution. Notably, the draft avoids the contentious issue of deep-sea mining, which lacks international consensus and faces criticism from environmentalists. The event's outcomes will be summarized in the Nice Ocean Action Plan, aiming for "zero rhetoric" and "maximum results" in ocean conservation.

🌡️ 4. Summer 2025 Forecast: Record Heat on the Way

NOAA has issued a warning that the summer of 2025 may be one of the hottest on record. Forecast models show above-average heat likely across most of the U.S., Europe, and parts of Asia.

Expected impacts include:

• Severe heat waves in urban centers
• Drought conditions in agricultural zones
• Increased pressure on energy systems and public health resources

The rising temperatures are largely attributed to long-term climate change trends, exacerbated by El Niño effects.

📦 5. Edible Packaging Innovation: Kodo Millet-Based Cups

In 2025, researchers from the Indian Institute of Technology (IIT) Roorkee developed edible cups made from Kodo millet, guar gum, and hibiscus powder. This sustainable packaging alternative aims to reduce plastic waste by offering a biodegradable and consumable option for food and beverage containers. The combination of natural ingredients enhances the structural integrity and moisture resistance of the cups, making them viable for real-world applications. This innovation represents a significant step toward environmentally friendly packaging solutions in the food industry.

💡 Final Thoughts

🌱 The push for sustainability is happening across sectors—from legislation and ocean cleanups to AI and consumer habits.

🍃 Whether it’s switching to eco-friendly packaging, supporting clean tech, or staying aware of climate risks, small steps contribute to a much bigger picture.
