Are bioplastics better for the environment than conventional plastics?

Despite advancements in technology in most sectors of life leading to an increase to access of information about practically anything, little is still known about the ocean and its behavioral patterns. Liquid Robotics – a Silicon Valley-based company – is trying to change that. Engineers here have created the "Wave Glider," which essentially acts as a router within the ocean powered by wave energy and solar panels. This invention can transmit data on tectonic activity that has the potential to predict tsunamis.

Two organizations in Pakistan are working to tackle the country’s waste problem. Saaf Suthra Sheher in Islamabad set up partnerships with offices and schools to process their dry waste like plastics and glass. TrashIt, a Karachi-based group, collects organic waste from vegetable sellers and restaurants and then processes and sells it as compost. Although the two organizations can only process so much of the waste produced in cities, they argue that until an effective municipal waste collection system is implemented, they can educate individuals and businesses about how to recycle properly.

After being known as a polluted mining town, politicians, scientists, industry officials, and residents of Sudbury, Ontario, were able to come together to restore its land. After 40 years and $33.5 million, they are about halfway through recovering about 200,000 acres of land. So far, they’ve been successful at restoring air quality, neutralizing soil to allow for replanting, and restocking lakes with fish. While some locals think the mining companies should have done more, the collaborative spirit could be a model for other communities looking to improve the environment.

As a way to combat climate change, scientists are experimenting with genetically modified trees as a way to draw carbon dioxide out of the atmosphere to store in its leaves, roots, and trunk. The startup Living Carbon has genetically modified poplar and pine seeds in the ground and expect them to be ready by the end of the year. Some scientists are worried about how these trees can impact forest ecosystems, but they grow faster than normal trees, allowing them to study and assess the risks quicker.

The state of Pennsylvania set to plant 86,000 hectares of riparian buffers, the practice of planting trees and shrubs along a river or stream to filter water. Other benefits of riparian buffers include things like restoring the soil and cooling the water. In order to meet their goal, the state scientists used a bottom approach, enlisting the help of local farmers by offering them grants to plant trees and showing farmers how they can profit off of riparian buffers. While the state is behind its goal, the state is planting about 1,000 to 2,000 hectares a year.

In 2020, a devastating explosion in Beirut that came from a warehouse released 800,000 and one million tons of construction and demolition waste and 20,000 tons of shattered glass into the city. The waste was being thrown into landfills. However, landfills are notoriously bad for the environment. Out of that rubble an idea was created; disposing waste sustainably. Rubble Mountains was created specifically to do this. They've been able to restore four quarries, use materials to create public amenities, and diverting up to 50 tons of demolition waste from landfills.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

The Nevada Irrigation District is restoring meadows, and therefore their carbon-sequestering abilities, in the Sierra Nevada mountains that were degraded by humans through things like building dams and mining.

Amidst water scarcity and increased waterborne diseases, community members are using sand dams, an innovative water management system, to conserve rainwater for daily use. Sand dams offer extended water storage capabilities, lasting up to a year, ensuring community members have consistent access to clean water for farming, cooking and general hygiene. There are currently six sand dams in the community serving 600 households.

Ramp Ring, una estructura poco convencional formada por seis grandes sacos de geotextil de alta resistencia, ayuda a regenerar las playas rápidamente y, con el tiempo, crear una base firme para nuevas tierras. Aprovecha el movimiento natural de la arena para proteger archipiélagos frente a la erosión y el aumento del nivel del mar.
