Researchers in Singapore invented a novel device that may help the island nation illuminate its growing underground infrastructure.
Researchers find that the coffee pulp is valuable in its own right.
Their success is based on us adopting a plant-based diet, too.
Natural ecosystems, such as forests, grasslands and oceans, do a pretty good job of storing carbon and supporting biodiversity.
Global carbon sequestration potential for current diets, those recommended by National Dietary Guidelines and others.

For instance, the <a href="https://www.weforum.org/communities/gfc-on-nature-based-solutions" target="_blank" rel="noopener noreferrer">Global Future Council on Nature-Based Solutions</a> is building support to "unlock more finance and catalyse meaningful action to enable a nature-positive economy". The WWF <a href="https://globallandusechange.org/en/projects/global-grassland-dialoque-platform/why-a-global-grassland-dialog-platform/" target="_blank" rel="noopener noreferrer">Global Grasslands and Savannahs Initiative</a> is elevating the importance of these often overlooked biomes to ensure that the pursuit of NbS and other activities doesn't drive more loss of grassland ecosystems, while the <a href="https://www.1t.org/" target="_blank" rel="noopener noreferrer">1t.org</a> initiative aims to plant a trillion trees. These are but a few examples of important global efforts to implement NbS. However, these efforts must also be accompanied with a renewed emphasis on dietary change to ensure a significant reduction in overall demand for land for food production.</p><p>There is no magic 'fix' to widespread adoption of healthy and sustainable diets. It requires hard work, political will and resources. There are some lessons, however, that can be drawn from past global transformations.</p><p>The first lesson is that no single actor or breakthrough is likely to catalyse systems change. Systems change will require actors at all scales and sectors engaged and working toward a shared set of goals. Secondly, science and evidence-gathering are keys to change, but lack of evidence must not be an excuse to delay action. The third lesson is that the full range of policy levers will be needed. It won't be enough to rely mainly on soft policy approaches, such as education campaigns or behavioural change initiatives. This must also be accompanied by regulatory or fiscal measures to ensure widespread adoption of healthy and sustainable diets.</p>
By 2050, there may be more plastic than fish in the sea.
- 2050 is predicted to be a bleak milestone for the oceans - but it's not too late to avert disaster.
- Here are 10 actions the world can take to strengthen and preserve our oceans for generations to come.
In May 2018, the city of Paris set an ambition to be carbon-neutral by 2050.
- Countries, governments and companies are aligning on a need for net-zero - and this is an opportunity to rethink decarbonizing our cities.
- There is no "one-size-fits-all" solution – each city's needs must be at the heart of developing integrated energy solutions.
- A city can only decarbonize through collaboration between government, the private sector, and local communities.
